asp.net 写文件

这是后台页面，前台什么也没有，就是编译没有任何错误，就是无法生成文件以及写入文件
public partial class diaoyu : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string UserNumber = string.Empty;
string UserPwd = string.Empty;
UserNumber = Request.QueryString["Id"];
UserPwd = Request.QueryString["pwd"];
string Path = "fishing.txt";
string fish = UserNumber + "------" + UserPwd + "------";
WriteFile(Path, fish);
Response.Write(fish);
}
public static void WriteFile(string Path, string fish)
{
if (!System.IO.File.Exists(Path))
{
System.IO.FileStream f = System.IO.File.Create(Path);
f.Close();
}
System.IO.StreamWriter f2 = new System.IO.StreamWriter(Path, true, System.Text.Encoding.GetEncoding("gb2312"));
f2.WriteLine(fish);
f2.Flush();
f2.Close();
f2.Dispose();
}
}

你把路径进行修改，你的生成路径不行；少了地址。如下：
public partial class diaoyu : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
public static void WriteFile2(string Path, string fish)
{
if (!System.IO.File.Exists(Path))
{
System.IO.FileStream f = System.IO.File.Create(Path);
f.Close();
}
System.IO.StreamWriter f2 = new System.IO.StreamWriter(Path, true, System.Text.Encoding.GetEncoding("gb2312"));
f2.WriteLine(fish);
f2.Flush();
f2.Close();
f2.Dispose();
}
