I have a project where I have multiple instances of an app running, each of which was started with different command line arguments. I'd like to have a way to click a button from one of those instances which then shuts down all of the instances and starts them back up again with the same command line arguments.

I can get the processes themselves easily enough through Process.GetProcessesByName(), but whenever I do, the StartInfo.Arguments property is always an empty string. It looks like maybe that property is only valid before starting a process.

This question had some suggestions, but they're all in native code, and I'd like to do this directly from .NET. Any suggestions?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
