I have a program that frequently uses an external program and reads its outputs.
It works pretty well using your usual process redirect output, but one specific argument for some reason hangs when I try to read it, no error message - no exception, it just &#39;stops&#39; when it reaches that line.
I of course use a centralized function to call and read output from the program, which is this:

    public string ADBShell(string adbInput)
    {
        try
        {
            //Create Empty values
            string result = string.Empty;
            string error = string.Empty;
            string output = string.Empty;
            System.Diagnostics.ProcessStartInfo procStartInfo 
                = new System.Diagnostics.ProcessStartInfo(toolPath + &quot;adb.exe&quot;);

            procStartInfo.Arguments = adbInput;
            procStartInfo.RedirectStandardOutput = true;
            procStartInfo.RedirectStandardError = true;
            procStartInfo.UseShellExecute = false;
            procStartInfo.CreateNoWindow = true;
            procStartInfo.WorkingDirectory = toolPath;
            System.Diagnostics.Process proc = new System.Diagnostics.Process();
            proc.StartInfo = procStartInfo;
            proc.Start();
            // Get the output into a string
            proc.WaitForExit();
            result = proc.StandardOutput.ReadToEnd();
            error = proc.StandardError.ReadToEnd();  //Some ADB outputs use this
            if (result.Length &gt; 1)
            {
                output += result;
            }
            if (error.Length &gt; 1)
            {
                output += error;
            }
            Return output;
        }
        catch (Exception objException)
        {
            throw objException;
        }
    }
The line that hangs is `result = proc.StandardOutput.ReadToEnd();`, but again, not every time, only when sent a specific argument (&quot;start-server&quot;). All other arguments work just fine - it reads the value and returns it.
It&#39;s also strange the way it hangs. It doesn&#39;t freeze or give an error or anything, it just stops processing. As if it was a &#39;return&#39; command, except it doesn&#39;t even return to the calling function, it just stops everything with the interface still up and running.
Anyone experienced this before? Anyone have any idea what I should try? I&#39;m assuming it&#39;s something unexpected within the stream itself, but is there a way I can handle/ignore this so that it reads it anyway?
