How to access a string from another method












0














How would I access the string filename from a different method?



    protected void AjaxFileUpload1_UploadComplete(object sender, AjaxControlToolkit.AjaxFileUploadEventArgs e)
{
filename = Server.MapPath("images/") + e.FileName.ToString();
AjaxFileUpload1.SaveAs(filename);
}


I have tried declaring filename in the scope of the class like this:



private string filename = String.Empty;


But when trying to access from another method like this:



public void GetFilename() 
{
lblResults.Text = filename;
}


The string is empty. What am I missing?

          It depends from the order you call your methods, if your call GetFilename() before AjaxFileUpload1_UploadComplete(...) has been called at least once. Your filename member will be empty, because you initialise it empty.



          As you are dealing with asynchronous, you should make sure to wait for filename to be set by your function.
