We can use a C# typeof keyword when we want to get Type instance

  • 0

We can use a C# typeof keyword when we want to get Type instance for specified type. But what can I use if I want to get MethodInfo of a method by it’s reference?

For example I have a simple console app. It contains Program.Main method. I want to get MethodInfo by using something like methodinfoof(Program.Main). I have this problem because the method names might change, so I cannot just use Type.GetMethodInfo(string MethodName) for that.

I have about 10 000 methods for which I would like to get MethodInfo, so adding any custom attributes or anything else to my methods is not a solution.

    Slight adaptation of a previously posted answer, but this blog post seems to achieve what you’re asking for; http://blog.functionalfun.net/2009/10/getting-methodinfo-of-generic-method.html

    Sample usage would be as follows;

    var methodInfo = SymbolExtensions.GetMethodInfo(() => Program.Main());
