How to Invoke Static Methods Using Reflection in C#?

Invoking Static Methods with Reflection

Problem:

You possess several static classes within the namespace mySolution.Macros, each containing static methods like:

public static class Indent
{
    public static void Run()
    {
        // implementation
    }
}

Your objective is to invoke these methods using reflection, even though they are static.

Solution:

To invoke static methods with reflection while preserving their static nature, employ the following approach:

foreach (var tempClass in macroClasses)
{
    // Note that the first argument is ignored for static methods
    tempClass.GetMethod("Run").Invoke(null, null);
}

As mentioned in the documentation for MethodInfo.Invoke, the first argument is redundant for static methods, so you can safely pass null.

Binding Flags:

It is important to note that you may need to specify binding flags when invoking the method, as suggested in the comment:

tempClass.GetMethod("Run", BindingFlags.Public | BindingFlags.Static).Invoke(null, null);

This ensures that the method is public and static, which is necessary for proper invocation.
