C#中的序列化而不使用文件系统

Serialization in C# without using file system

提问by Nathan DeWitt

I have a simple 2D array of strings and I would like to stuff it into an SPFieldMultiLineText in MOSS. This maps to an ntext database field.

我有一个简单的 2D 字符串数组，我想将它填充到 MOSS 中的 SPFieldMultiLineText 中。这映射到 ntext 数据库字段。

I know I can serialize to XML and store to the file system, but I would like to serialize without touching the filesystem.

我知道我可以序列化为 XML 并存储到文件系统，但我想在不接触文件系统的情况下进行序列化。

public override void ItemAdding(SPItemEventProperties properties)
{
    // build the array
    List<List<string>> matrix = new List<List<string>>();
    /*
    * populating the array is snipped, works fine
    */
    // now stick this matrix into the field in my list item
    properties.AfterProperties["myNoteField"] = matrix; // throws an error
}

Looks like I should be able to do something like this:

看起来我应该能够做这样的事情：

XmlSerializer s = new XmlSerializer(typeof(List<List<string>>));
properties.AfterProperties["myNoteField"] = s.Serialize.ToString();

but that doesn't work. All the examples I've found demonstrate writing to a text file.

但这不起作用。我发现的所有示例都演示了写入文本文件。

StringWriter outStream = new StringWriter();
XmlSerializer s = new XmlSerializer(typeof(List<List<string>>));
s.Serialize(outStream, myObj);
properties.AfterProperties["myNoteField"] = outStream.ToString();

IN VB.NET

在 VB.NET 中

Public Shared Function SerializeToByteArray(ByVal object2Serialize As Object) As Byte()
    Using stream As New MemoryStream
        Dim xmlSerializer As New XmlSerializer(object2Serialize.GetType())
        xmlSerializer.Serialize(stream, object2Serialize)
        Return stream.ToArray()
    End Using
End Function

Public Shared Function SerializeToString(ByVal object2Serialize As Object) As String
    Dim bytes As Bytes() = SerializeToByteArray(object2Serialize)
    Return Text.UTF8Encoding.GetString(bytes)
End Function

IN C#

在 C# 中

public byte[] SerializeToByteArray(object object2Serialize) {
       using(MemoryStream stream = new MemoryStream()) {
          XmlSerializer xmlSerializer = new XmlSerializer(object2Serialize.GetType());
          xmlSerializer.Serialize(stream, object2Serialize);
          return stream.ToArray();
       }
}

public string SerializeToString(object object2Serialize) {
   byte[] bytes = SerializeToByteArray(object2Serialize);
   return Text.UTF8Encoding.GetString(bytes);
}

Use the TextWriter and TextReader classes with the StringWriter.

将 TextWriter 和 TextReader 类与 StringWriter 一起使用。

To Wit:

以机智：

XmlSerializer s = new XmlSerializer(typeof(whatever));
TextWriter w = new StringWriter();
s.Serialize(w, whatever);
yourstring = w.ToString();

Here's a Generic serializer (C#):

这是一个通用序列化程序（C#）：

    public string SerializeObject<T>(T objectToSerialize)
    {
        BinaryFormatter bf = new BinaryFormatter();
        MemoryStream memStr = new MemoryStream();

        try
        {
            bf.Serialize(memStr, objectToSerialize);
            memStr.Position = 0;

            return Convert.ToBase64String(memStr.ToArray());
        }
        finally
        {
            memStr.Close();
        }
    }

In your case you could call with:

在您的情况下，您可以致电：

    SerializeObject<List<string>>(matrix);
