How to Effectively Capture Child Process STDOUT in .NET?

Efficiently Capturing Child Process Output in .NET

This article examines methods for launching a console application as a child process and retrieving its output within a .NET environment. While event handlers and redirection are common approaches, they can sometimes prove unreliable.

A straightforward solution involves directly reading the child process's standard output stream:

<code class="language-csharp">return p.StandardOutput.ReadToEnd();</code>

This concise method reads the entire output and returns it as a string.

Alternatively, for more granular control, event handling offers a line-by-line approach:

<code class="language-csharp">process.OutputDataReceived += (sender, args) => Console.WriteLine("received output: {0}", args.Data);</code>

This method processes output incrementally, enabling real-time handling. The choice between these techniques depends on the application's specific needs and whether immediate or complete output retrieval is preferred.
