从MemoryStream返回包含xml内容的字符串

Question

为什么我的返回内容始终为空;

  using (MemoryStream ms = new MemoryStream()) 
      { 
       StreamWriter sw = new StreamWriter(ms, System.Text.Encoding.GetEncoding(1252)); 
       XDocument xdoc = new XDocument(root); 
       xdoc.Save(sw); 

       using (StreamReader sr = new StreamReader(ms, System.Text.Encoding.GetEncoding(1252), true)) 
       { 
        string content = sr.ReadToEnd(); 
        return content; 
       } 
      } 

Answer 1

您应该使用

sw.Flush(); 
ms.Position = 0; 

你流的起点复位，以阅读agian。
