Getting a delegate from methodinfo

I have a drop down list that is populated by inspecting a class's methods and including those that match a specific signature. The problem is in taking the selected item from the list and getting the delegate to call that method in the class. The first method works, but I cannot figure out part of the second.

For example,

public delegate void MyDelegate(MyState state);

public static MyDelegate GetMyDelegateFromString(string methodName)
{
    switch (methodName)
    {
        case "CallMethodOne":
            return MyFunctionsClass.CallMethodOne;
        case "CallMethodTwo":
            return MyFunctionsClass.CallMethodTwo;
        default:
            return MyFunctionsClass.CallMethodOne;
    }
}

public static MyDelegate GetMyDelegateFromStringReflection(string methodName)
{
    MyDelegate function = MyFunctionsClass.CallMethodOne;

    Type inf = typeof(MyFunctionsClass);
    foreach (var method in inf.GetMethods())
    {
        if (method.Name == methodName)
        {
            //function = method;
            //how do I get the function to call?
        }
    }

    return function;
}

How do I get the commented out section of the second method to work? How do I cast the MethodInfo into the delegate?

Thanks!

Edit: Here is the working solution.

public static MyDelegate GetMyDelegateFromStringReflection(string methodName)
{
    MyDelegate function = MyFunctionsClass.CallMethodOne;

    Type inf = typeof(MyFunctionsClass);
    foreach (var method in inf.GetMethods())
    {
        if (method.Name == methodName)
        {
            function = (MyDelegate)Delegate.CreateDelegate(typeof(MyDelegate), method);
        }
    }

    return function;
}
