Question

private static void runantc_OutputDataReceived(object sendingProcess, DataReceivedEventArgs outLine)  
        {
            // Collect the sort command output.
            if (!String.IsNullOrEmpty(outLine.Data))
            {
                ProcoutputTextBlock.Dispatcher.BeginInvoke(new Action(() => { ProcoutputTextBlock.Text += outLine.Data; }, null));
            }
        }

Hi, in the above code i am having errors @ProcoutputTextBlock Error 1 An object reference is required for the non-static field, method, or property ‘WpfApplication1.Window1.ProcoutputTextBlock’

and @ () => { ProcoutputTextBlock.Text += outLine.Data; }, null
Error 2 Method name expected

can anybody enlighten me?

Answer 1

ProcoutputTextBlock is an instance property. You are accessing instance property from static method runantc_OutputDataReceived.

To resolve this remove static from runantc_OutputDataReceived declaration.

To fix the second issue, remove the second argument null. Like this:

ProcoutputTextBlock.Dispatcher.BeginInvoke(new Action(() => { ProcoutputTextBlock.Text += outLine.Data; }));

or

ProcoutputTextBlock.Dispatcher.BeginInvoke((Action)(() => { ProcoutputTextBlock.Text += outLine.Data; }));
