Modifying .resx file in C#
提问by
I have a .resxfile that contains name-value pairs (both strings). Now I want to modify the values in certain name-value pairs programmatically using C#. How can I achieve that?
我有一个.resx包含名称-值对（两个字符串）的文件。现在我想使用 C# 以编程方式修改某些名称-值对中的值。我怎样才能做到这一点？

There's a whole namespace for resource management: System.Resources. Check out the ResourceManager class, as well as ResXResourceReader and ResXResourceWriter.
有一个用于资源管理的完整命名空间：System.Resources。查看 ResourceManager 类，以及 ResXResourceReader 和 ResXResourceWriter。

I managed to lay my hands on a very old debug method that I used to use at one point when I was testing some resource related stuff. This should do the trick for you.
我设法掌握了一种非常古老的调试方法，我曾经在测试一些与资源相关的东西时使用过这种方法。这应该对你有用。
public static void UpdateResourceFile(Hashtable data, String path)
{
Hashtable resourceEntries = new Hashtable();
//Get existing resources
ResXResourceReader reader = new ResXResourceReader(path);
if (reader != null)
{
IDictionaryEnumerator id = reader.GetEnumerator();
foreach (DictionaryEntry d in reader)
{
if (d.Value == null)
resourceEntries.Add(d.Key.ToString(), "");
else
resourceEntries.Add(d.Key.ToString(), d.Value.ToString());
}
reader.Close();
}
//Modify resources here...
foreach (String key in data.Keys)
{
if (!resourceEntries.ContainsKey(key))
{
String value = data[key].ToString();
if (value == null) value = "";
resourceEntries.Add(key, value);
}
}
//Write the combined resource file
ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
foreach (String key in resourceEntries.Keys)
{
resourceWriter.AddResource(key, resourceEntries[key]);
}
resourceWriter.Generate();
resourceWriter.Close();
}

Womp got it right (10x).
Womp 做对了（10 倍）。
But here is a code that keeps the XML file order, add new at the end of the file. (for source control)
但这里有一个保持 XML 文件顺序的代码，在文件末尾添加新的。（用于源代码控制）
//Need dll System.Windows.Forms
public static void UpdateResourceFile(Hashtable data, String path)
{
Hashtable resourceEntries = new Hashtable();
//Get existing resources
ResXResourceReader reader = new ResXResourceReader(path);
ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
if (reader != null)
{
IDictionaryEnumerator id = reader.GetEnumerator();
foreach (DictionaryEntry d in reader)
{
//Read from file:
string val = "";
if (d.Value == null)
resourceEntries.Add(d.Key.ToString(), "");
else
{
resourceEntries.Add(d.Key.ToString(), d.Value.ToString());
val = d.Value.ToString();
}
//Write (with read to keep xml file order)
resourceWriter.AddResource(d.Key.ToString(), val);
}
reader.Close();
}
//Add new data (at the end of the file):
Hashtable newRes = new Hashtable();
foreach (String key in data.Keys)
{
if (!resourceEntries.ContainsKey(key))
{
String value = data[key].ToString();
if (value == null) value = "";
resourceWriter.AddResource(key, value);
}
}
//Write to file
resourceWriter.Generate();
resourceWriter.Close();
}

If you want to keep the existing comments in the resource files then use this (Based on SirMoreno's code modified)
如果你想在资源文件中保留现有的注释，那么使用这个（基于 SirMoreno 的代码修改）
public static void UpdateResourceFile(Hashtable data, String path)
{
Hashtable resourceEntries = new Hashtable();
//Get existing resources
ResXResourceReader reader = new ResXResourceReader(path);
reader.UseResXDataNodes = true;
ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
System.ComponentModel.Design.ITypeResolutionService typeres = null;
if (reader != null)
{
IDictionaryEnumerator id = reader.GetEnumerator();
foreach (DictionaryEntry d in reader)
{
//Read from file:
string val = "";
if (d.Value == null)
resourceEntries.Add(d.Key.ToString(), "");
else
{
val = ((ResXDataNode)d.Value).GetValue(typeres).ToString();
resourceEntries.Add(d.Key.ToString(), val);
}
//Write (with read to keep xml file order)
ResXDataNode dataNode = (ResXDataNode)d.Value;
//resourceWriter.AddResource(d.Key.ToString(), val);
resourceWriter.AddResource(dataNode);
}
reader.Close();
}
//Add new data (at the end of the file):
Hashtable newRes = new Hashtable();
foreach (String key in data.Keys)
{
if (!resourceEntries.ContainsKey(key))
{
String value = data[key].ToString();
if (value == null) value = "";
resourceWriter.AddResource(key, value);
}
}
//Write to file
resourceWriter.Generate();
resourceWriter.Close();
}

public static void AddOrUpdateResource(string key, string value)

using (var reader = new ResXResourceReader(resourceFilepath))

var existingResource = resx.Where(r => r.Key.ToString() == key).FirstOrDefault();
if (existingResource.Key == null && existingResource.Value == null) // NEW!

resx.Add(new DictionaryEntry() { Key = key, Value = value });
}
else // MODIFIED RESOURCE!
{
var modifiedResx = new DictionaryEntry()

resx.Remove(existingResource); // REMOVING RESOURCE!
resx.Add(modifiedResx); // AND THEN ADDING RESOURCE!

}
using (var writer = new ResXResourceWriter(ResxPathEn))

This is my version based on Ers' and based on SirMoreno's code. Just a little shorter. This is still not handeling metaData which is possible but not necessasry for me.
这是我基于 Ers 和 SirMoreno 代码的版本。就是短一点。这仍然不是处理元数据，这对我来说是可能的，但不是必需的。
public static bool AddToResourceFile(string key, string value, string comment, string path)
{
using (ResXResourceWriter resourceWriter = new ResXResourceWriter(path))
{
//Get existing resources
using (ResXResourceReader reader = new ResXResourceReader(path) { UseResXDataNodes = true })
{
foreach (DictionaryEntry resEntry in reader)
{
ResXDataNode node = resEntry.Value as ResXDataNode;
if (node == null) continue;
if (string.CompareOrdinal(key, node.Name) == 0)
{
// Keep resources untouched. Alternativly modify this resource.
return false;
}
resourceWriter.AddResource(node);
}
}
//Add new data (at the end of the file):
resourceWriter.AddResource(new ResXDataNode(key, value) { Comment = comment });
//Write to file
resourceWriter.Generate();
}
return true;
}

This is improved Womp's answer - without obsolete Hashtable, checking if file exists and using LINQ:
这是改进的 Womp 答案 - 没有过时的 Hashtable，检查文件是否存在并使用 LINQ：
public static void UpdateResourceFile(Dictionary<string, string> data, string path)
{
Dictionary<string, string> resourceEntries = new Dictionary<string, string>();
if (File.Exists(path))
{
//Get existing resources
ResXResourceReader reader = new ResXResourceReader(path);
resourceEntries = reader.Cast<DictionaryEntry>().ToDictionary(d => d.Key.ToString(), d => d.Value?.ToString() ?? "");
reader.Close();
}
//Modify resources here...
foreach (KeyValuePair<string, string> entry in data)
{
if (!resourceEntries.ContainsKey(entry.Key))
{
if (!resourceEntries.ContainsValue(entry.Value))
{
resourceEntries.Add(entry.Key, entry.Value);
}
}
}
string directoryPath = Path.GetDirectoryName(path);
if (!string.IsNullOrEmpty(directoryPath))
{
Directory.CreateDirectory(directoryPath);
}
//Write the combined resource file
ResXResourceWriter resourceWriter = new ResXResourceWriter(path);
foreach (KeyValuePair<string, string> entry in resourceEntries)
{
resourceWriter.AddResource(entry.Key, resourceEntries[entry.Key]);
}
resourceWriter.Generate();
resourceWriter.Close();
}

All of the other answers make use of ResXResourceWriter, but for certain special cases it may be feasible and better to simply work with the Resources.resx file as an XML document.
所有其他答案都使用 ResXResourceWriter，但对于某些特殊情况，将 Resources.resx 文件作为 XML 文档简单地使用可能是可行且更好的。
I have a specific situation where I want to manipulate the Resources.resx entries for a set of icon files. There may be up to several hundred entries, and I can count on them all looking exactly like this:
我有一个特定的情况，我想操作一组图标文件的 Resources.resx 条目。可能有多达数百个条目，我可以指望它们看起来完全像这样：
<data name="Incors_workplace2_16x16" type="System.Resources.ResXFileRef, System.Windows.Forms">
<value>..\..\..\..\..\..\Icons\Incors-workplace2-16x16.png;System.Drawing.Bitmap, System.Drawing, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a</value>
</data>
I tried using ResXResourceWriter and ResXResourceReader for this program, but I ended up instead opening the various Resources.resx files as XML documents and manipulating them in that way. The whole program is much too large (and too application-specific) to post here, but I'll post a few stumps of code to show some of the techniques that can be used.
我尝试在该程序中使用 ResXResourceWriter 和 ResXResourceReader，但最终我将各种 Resources.resx 文件作为 XML 文档打开并以这种方式操作它们。整个程序太大（也太特定于应用程序），无法在此处发布，但我将发布一些代码以展示一些可以使用的技术。
