             string c = lbl1filename.Text.ToString();

             //string extension = System.IO.Path.GetExtension(upload.FileName);

             string nfilepath;
             nfilepath = "D:\\saravana\\Spatiotemporal Approach\\SourceMain\\source_uploadfiles\\" + c;
             try
             {
                 upload.SaveAs("D:\\saravana\\Spatiotemporal Approach\\SourceMain\\source_uploadfiles\\" + c);

             SqlCommand cmd = new SqlCommand();
             cmd.Connection = con;
             cmd.CommandType = CommandType.Text;
             cmd.CommandText = "insert into filedetails(filename,filetype,filepath) values('" + lbl1filename.Text + "','" + nfilepath + "')";
             if (con.State == ConnectionState.Closed)

推荐答案

尝试通过代码进行调试.
请注意您在哪里得到错误.

检查文件是否存在于硬编码的文件路径中.

Try debugging through the code.
Note where you get the error.

Check if the file exists at the hardcoded file path.

if (FileUploadControl.HasFile)
               {
                   try
                   {
                       filename = Path.GetFileName(FileUploadControl.FileName);
                       FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
                       objInwardLetter.strPath = "~/" + filename;

}
赶上
{}
}

}
catch
{}
}
