用FileStream打开的文本文件,用StreamReader读取的字符串中汉字无法正确的显示

[xhan2000]

StreamReader sr=new StreamReader("c:\\x.txt",System.Text.Encoding.Default);

string x=sr.ReadToEnd();
sr.Close();

using System.IO;


StreamReader sr = new StreamReader("YourFileName", System.Text.Encoding.GetEncoding("GB2312"));

String s = sr.ReadToEnd();

sr.Close();
