file copy progress bar

good day all

i know how can make progress bar copying file.

i not sure if should use buffer or copy bytes copied , forth.

thank you

just move code posted button click event , source , destination textboxes:

    private void button1_click(object sender, eventargs e)     {       webclient wc = new webclient();       wc.downloadprogresschanged += downloadprogress;       wc.downloadfileasync(new uri(sourcetextbox.text), destinationtextbox.text);     }     void downloadprogress(object sender, downloadprogresschangedeventargs e)     {       progressbar1.value = e.progresspercentage;     }

code runs asynchronously keeping ui responsive.
