在C＃Windows窗体中重定向schtasks输出

Question

I have an issue that I can not figure out. I have a Windows form with a Text Box, Button, and List Box. I want to type an IP into the text box, push the button, and redirect the schtasks output to my list box. However, I never get anything more than the first line. Also, my code works fine when redirecting to a text file. Below is my code.

        string machineName = textBox1.Text;

        Process process = new Process();
        process.StartInfo.FileName = "schtasks";
        process.StartInfo.Arguments = " /query /s " + machineName;
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.RedirectStandardOutput = true;
        process.StartInfo.CreateNoWindow = true;
        process.Start();

        string output = process.StandardOutput.ReadToEnd();
        process.WaitForExit();

        lstOutput.Items.Add(output);

My code to write to text file was the same except at the end, instead of writing to the listbox, I created a text writer and gave it a location for the file. Can anyone figure out what I have done wrong?

I think you need to parse the output more to massage it into the list box. I ran your example with a textbox and got all of the output, just like at a command line. I think the list box is just adding all of the output as one item maybe?

Try something like this:

    string[] lines = output.Split('\n');
    foreach (string s in lines)
    {
        lbResult.Items.Add(s);
    }
