Trying to get StandardOutput after running a console process

I can run a console process using the following C# code. The goal is also to collect all the output from such process:

System.Diagnostics.Process proc = new System.Diagnostics.Process();

proc.StartInfo.Arguments = commandLine;
proc.StartInfo.FileName = "signtool.exe";
proc.StartInfo.RedirectStandardOutput = true;

proc.StartInfo.UseShellExecute = false;

proc.Start();

if (proc.WaitForExit(10000))
{
    Debug.WriteLine(proc.StandardOutput.ReadToEnd());
}

What I receive is this:

"Done Adding Additional Store\r\n"

But when I do the same from a Windows command line I get this:

Done Adding Additional Store
SignTool Error: File not found: C:\SomeBadFile.exe

Why am I getting only the first line of output with my code?

Have you tried redirecting and watching StandardError too? It seem likley that this is output to the error stream.

Seeing as the line you are missing seems like an error message, should you not be looking at Process.StandardError Property

When a Process writes text to its standard error stream, that text is normally displayed on the console. By redirecting the StandardError stream, you can manipulate or suppress the error output of a process. For example, you can filter the text, format it differently, or write the output to both the console and a designated log file.
