以下是一段asp.net读取excel的源代码：

1.读

System.IO.StreamReader my = new System.IO.StreamReader("F:\\my.txt", System.Text.Encoding.Default);
string line;
while((line=my.ReadLine())!=null)
{
Response.Write(line+"<br />");
}
my.Close();

2.写

System.IO.StreamWriter myWrite = new System.IO.StreamWriter("F:\\mymy.txt", true, System.Text.Encoding.Default);
myWrite.WriteLine("哈哈");
myWrite.WriteLine("我很好");
myWrite.Flush();
myWrite.Close();
