Answer 1

StreamReader sr = new StreamReader(@"E:\银狐\朋友.txt", Encoding.GetEncoding("gb2312"));

Answer 2

string FileName = @"E:\银狐\朋友.txt";
               if (File.Exists(FileName))
                {
                   //读取指定的文本文件,并支持中文编码字符  
                   StreamReader objReader =
                   new StreamReader(FileName, System.Text.Encoding.GetEncoding("gb2312"));
                    string aa = objReader.ReadToEnd();
                   objReader.Close();//关闭流
