Retrieving the MethodInfo of of the correct overload of a generic method

Question

I have this type that contains two overloads of a generic method. I like to retrieve one of the overloads (with the Func parameter) using reflection. T

Why don't you use expression trees? This makes it much easier:

public static MethodInfo GetMethod(
    Expression> methodSelector)
{
    var body = (MethodCallExpression)methodSelector.Body;
    return body.Method;      
}

[TestMethod]
public void Test1()
{
    var expectedMethod = typeof(Foo)
        .GetMethod("Bar", new Type[] { typeof(Func<>) });

    var actualMethod = 
        GetMethod(foo => foo.Bar
