为什么文件读出来的中文字符是乱码？

[lxxlily]

if (System.IO.File.Exists(Hfile_SelectFile.Value))
{
System.IO.StreamReader m_fs = System.IO.File.OpenText(Hfile_SelectFile.Value);
m_fs.ReadLine();
while(m_fs.Peek()!=-1)
{
m_arrFileText.Add(m_fs.ReadLine());
}
m_fs.Close();
......

StreamReader sr =
new StreamReader(@"c:\test\Uncode_fan.txt",Encoding.GetEncoding("Gb2312"));
string aaa = sr.ReadToEnd();

[yungboy]

<globalization
requestEncoding="gb2312"
responseEncoding="gb2312"
/>

或者

<META http-equiv="content-type" content="text/html; charset=gb2312">

指定编码：
help://MS.VSCC.2003/MS.MSDNQTR.2003FEB.2052/cpref/html/frlrfSystemIOStreamWriterClassEncodingTopic.htm
eg;
StreamWriter.Encoding = System.Text.Encoding.Default(utf-8)

[Tony8002003]

在HTML里加：
<META http-equiv="content-type" content="text/html; charset=gb2312">

[fmj1980]

System.IO.StreamReader m_fs = System.IO.File.OpenText(Hfile_SelectFile.Value);
改为
System.IO.StreamReader m_fs = new System.IO.StreamReader(Hfile_SelectFile.Value,System.Text.Encoding.GetEncoding("gb2312"));

在Web.config文件中有个关于编码的选项，改为GB2312就支持中文了
