How to check whether File-Upload control contains any file or not?

Answer:

With the help of HasFile property of File-Upload control,we can check whether File-Upload control contains any file or not.

It returns true if File-Upload control contains any file(s) otherwise returns false.

For Example:-

if(fld_upload.HasFile)

{

   //it contains file

}

else

{

    //it does not contain any file

}

Where,fld_upload is our Asp.Net File upload control.
