Check that the upload file is not empty

string FullName = MyFile.PostedFile.FileName;
Get the related attributes of this file: file name, file type, file size
This.fname.Text = MyFile.PostedFile.FileName;
This.fenc.Text = MyFile.PostedFile.ContentType;
This.fsize.Text = myFile.PostedFile.ContentLength.ToString () + "bytes";
Gets the index of the last "\" in the filename (enclosing path)
Int J = fullname.lastindexof ("\ \");
Get file name
String simplename = Fullname.substring (j);
Save the file to the directory you want, this is the Uploadnote directory under the IIS root directory. You can change.
Use Server.MapPath () to take the absolute directory of the current file. In asp.net, "\" is an escape character and must be replaced with "\"
String FilePath = Server.MapPath ("\\UpLoadNote");
MyFile.PostedFile.SaveAs ("D:\\test\\aa.doc");
MyFile.PostedFile.SaveAs (FilePath + simplename);
Response.Write (Server.machinename);
}

{
Labelerror.text = "Please select the file to upload!" ";
