如何編碼memorystream對象字符串在Windows 8中使用C＃？

Question

如何將memorystream對象編碼爲使用c＃在Windows 8中的字符串？

代碼段：

DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType()); 
     using (MemoryStream ms = new MemoryStream()) 
     { 
      serializer.WriteObject(ms, obj); 

      //return Encoding.Default.GetString(ms.ToArray()); //problem in this line 
     } 

Answer 1

閱讀Unicode and .NET和使用

Encoding.UTF8.GetString(ms.ToArray()); 

Answer 2

ms.Seek(0, SeekOrigin.Begin); 
StreamReader reader = new StreamReader(ms); // or whatever encoding 
return reader.ReadToEnd();
