Property Value
A Byte array that contains the contents of the specified file.The FileUpload control does not automatically read the file from the client. You must explicitly provide a control or mechanism to allow the user to submit the specified file. For example, you can provide a button that the user can click to upload the file. The code that you write to save the specified file could call the FileBytes property, which returns the contents of the file.
Before calling the FileBytes property, you should use the HasFile property to verify that the FileUpload control contains a file to upload. If the HasFile returns true, call the FileBytes property. If it returns false, display a message to the user indicating that the control does not contain a file. If you do not provide error-handling code to verify that a file exists, an attempt to save a nonexistent file throws an HttpException exception.
