推荐答案

正如KR在评论中提到的那样，Server.MapPath需要一个虚拟路径。所以你不会一遍又一遍地在同一个字符串上调用它。

As KR mentioned in comments, Server.MapPath expects a virtual path. So you would not keep calling it over and over on the same string.

string FileName = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
string Fp = "~/images/" + FileName; // ~ means you'll get a virtual path starting at the root of the application.  This is good.
string FilePath = Server.MapPath(Fp);  // this will give you something like "c:\inetpub\wwwroot\website1\images\filename
FileUpload1.SaveAs(FilePath);

试试这个。您使用过 MapPath 两次，实际上并不需要。

Try this. You have used MapPath twice, which is not needed actually.

FileUpload1.SaveAs(Server.MapPath(@"~/images/" + filename));

protected void btnUpload_Click(object sender, EventArgs e)
    {
        if (FileUpload1.HasFile)
        {
            string FileName = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
            string Fp = @"~/images/" + FileName;
            string FilePath = Server.MapPath(Fp); 
            FileUpload1.SaveAs(FilePath);
            RichTextBox.Text += string.Format("<img src = '{0}' alt = '{1}' />", Fp, FileName);
        }
    }
