获取任意可序列化对象的Xml字符串，方便在日志中查看任一所感兴趣的对象。

代码：

public static string GetLoggingString(this object obj)

{

    using (var stream = new MemoryStream())

    {

        new XmlSerializer(obj.GetType()).Serialize(stream, obj);

        stream.Position = 0;

        var buffer = new byte[stream.Length];

        stream.ReadAsync(buffer, 0, buffer.Length);

        stream.FlushAsync();

        return Encoding.UTF8.GetString(buffer);

    }

} 

用法：

var list = new List<string> { "abs", "sdf", "srer" };

var d = list.GetLoggingString();

结果：

<?xml version="1.0"?>

<ArrayOfString xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  <string>abs</string>

  <string>sdf</string>

  <string>srer</string>

</ArrayOfString>
