c#如何来读入中文内容的txt文件

[school0911]

我想把中文内容的txt文件里的内容读到程序里的字符串中，读到的内容都是乱码，请问如何才能读入正确的中文内容？

StreamWriter sw = File.CreateText(@"d:\a.txt");
sw.Write("hello");
sw.WriteLine("hello");
sw.Close()

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

[bitsbird]

StreamReader sw = File.OpenText(@"d:\a.txt");
string str;
while((str =sw.ReadLine()) != null)
{
textBox2.Text = str;
}

using System.IO
StreamReader str=new StreamReader(@"c:\t.txt",System.Text.Encoding.Default);
str.WriteLine("xxxx");

System.Text.Encoding.Default是关键
