重命名文件夹c#中的文件

Renaming files in folder c#

提问by Jason Paddle

I have over 1000 files in a folder with names like abc_1, abc_2 ... abc_n

我在一个文件夹中有 1000 多个文件，名称类似于 abc_1、abc_2 ... abc_n

I want to delete this prefix 'abc_' from all the files. Any chance to not doing this manually because there are over 1000, and it will be a pain.

我想从所有文件中删除这个前缀“abc_”。任何不手动执行此操作的机会，因为有 1000 多个，这将是一种痛苦。

How can do this with c# ?

如何用 c# 做到这一点？

You can try with this code

您可以尝试使用此代码

DirectoryInfo d = new DirectoryInfo(@"C:\DirectoryToAccess");
FileInfo[] infos = d.GetFiles();
foreach(FileInfo f in infos)
{
    File.Move(f.FullName, f.FullName.Replace("abc_",""));
}

you can use a foreach iteration along with the File class from the System.IO namespace.

您可以将 foreach 迭代与 System.IO 命名空间中的 File 类一起使用。

You can enumerate the file.

您可以枚举文件。

using System.IO;

string[] filePaths = Directory.GetFiles(@"c:\MyDir\");

Then, ForEach the string[] and create a new instance of the IO.Fileobject.

然后，ForEach 字符串[] 并创建IO.File对象的新实例。

Once you get a handle on a File, just call the Move method and pass in String.Replace("abc_", String.Empty).

一旦获得文件的句柄，只需调用 Move 方法并传入 String.Replace("abc_", String.Empty)。

I said Move because there is no direct Rename method in IO.File.

我说Move是因为IO.File中没有直接的Rename方法。

File.Move(oldFileName, newFileName);

File.Move(oldFileName, newFileName);

Be mindful of the extension.

请注意扩展名。

Total Commanderhas the possibility to rename multiple files(You don't need to program a tool on your own for each little task).

Total Commander可以重命名多个文件（您不需要为每个小任务自己编写一个工具）。

You can use File.Moveand String.Substring(index):

您可以使用File.Move和String.Substring(index)：

var prefix = "abc_";
var rootDir = @"C:\Temp";
var fileNames = Directory.EnumerateFiles(rootDir, prefix + "*", SearchOption.AllDirectories);
foreach(String path in fileNames)
{
    var dir = Path.GetDirectoryName(path);
    var fileName = Path.GetFileName(path);
    var newPath = Path.Combine(dir, fileName.Substring(prefix.Length));
    File.Move(path, newPath);
}

Note: Directory.EnumerateFiles(rootDir, prefix + "*", SearchOption.AllDirectories);will search also subfolders from your root directory. If this is not intended use SearchOption.TopDirectoryOnly.

注意：Directory.EnumerateFiles(rootDir, prefix + "*", SearchOption.AllDirectories);还将搜索根目录中的子文件夹。如果这不是预期用途SearchOption.TopDirectoryOnly。

You should have a look at the DirectoryInfoclass and GetFiles() Method. And have a look at the Fileclass which provides the Move() Method.

您应该查看DirectoryInfo类和 GetFiles() 方法。并查看提供 Move() 方法的File类。

File.Move(oldFileName, newFileName);

string path = @"C:\NewFolder\";    
string[] filesInDirectpry = Directory.GetFiles(path, "abc*");
forearch(string file in filesInDirectory)
{
    FileInfo fileInfo = new FileInfo(file);
    fileInfo.MoveTo(path + "NewUniqueFileNamHere");
}

Following code will work, not tested though,

以下代码将起作用，但未经测试，

 public class FileNameFixer
    {
        public FileNameFixer()
        {
            StringToRemove = "_";
            StringReplacement = "";


        }
        public void FixAll(string directory)
        {
            IEnumerable<string> files = Directory.EnumerateFiles(directory);
            foreach (string file in files)
            {
                try
                {
                    FileInfo info = new FileInfo(file);
                    if (!info.IsReadOnly && !info.Attributes.HasFlag(FileAttributes.System))
                    {
                        string destFileName = GetNewFile(file);
                        info.MoveTo(destFileName);
                    }
                }
                catch (Exception ex)
                {
                    Debug.Write(ex.Message);
                }
            }
        }

        private string GetNewFile(string file)
        {
            string nameWithoutExtension = Path.GetFileNameWithoutExtension(file);
            if (nameWithoutExtension != null && nameWithoutExtension.Length > 1)
            {
                return Path.Combine(Path.GetDirectoryName(file),
                    file.Replace(StringToRemove, StringReplacement) + Path.GetExtension(file));
            }
            return file;
        }

        public string StringToRemove { get; set; }

        public string StringReplacement { get; set; }
    }

you can use this class as,

你可以使用这个类，

  FileNameFixer fixer=new FileNameFixer();
        fixer.StringReplacement = String.Empty;
        fixer.StringToRemove = "@@";
        fixer.FixAll("C:\temp");

This command would do the trick, using renamer:

这个命令可以解决这个问题，使用renamer：

I like the simplicity of the answer with the most up-votes, but I didn't want the file path to get modified so I changed the code slightly ...

我喜欢答案的简单性和最多的投票，但我不想修改文件路径，所以我稍微更改了代码......

string searchString = "_abc_";
string replaceString = "_123_";
string searchDirectory = @"\unc\path\with\slashes\";
int counter = 0;
DirectoryInfo d = new DirectoryInfo(searchDirectory);
FileInfo[] infos = d.GetFiles();
foreach(FileInfo f in infos)
{
    if (f.Name.Contains(searchString)) 
    {
        File.Move(searchDirectory+f.Name, searchDirectory+ f.Name.Replace(searchString, replaceString));
        counter++;
    }
}
Debug.Print("Files renamed" + counter);
