C Sharp : Invoking a method dynamically using a name of method string

Here's my attempts to dynamically call a method using just the name of the method as a string. You may follow a similar line of thought. 

The examples below will call a method within the same class. 

Here's method signature I am trying to invoke

1	public void GetText(object sender, EventArgs e) //sender is a menuitem

1 st attempt

1 2	string methodName = "GetText"; Action<string> myAction = new Action<string>(methodName);

Error : methodName is a variable but used like a method

2nd attempt

1 2	string methodName = "GetText"; Func<string, string> funky = new Func<string, string>(methodName);

Error : methodName is a variable but used like a method

3rd attempt

1 2 3 4 5 6 7 8

string methodName = "GetText"; Type callerType = this.GetType(); string output = (string)callerType.InvokeMember( methodName, BindingFlags.InvokeMethod, null, null, null);

Error Method 'Program.Class.methodName' not found. Issue args does not match the method signature.


4th attempt - Correct method args

1 2 3 4 5 6 7

string output = (string)callerType.InvokeMember( methodName, BindingFlags.InvokeMethod, null, null, new Object[] { sender, e } );

Error "Non-static method requires a target. Issue incorrect return type, this case it must be void.


5th attempt - works but

1 2 3 4 5 6 7 8 9 10

//create instance assuming default constructor object obj = callerType.InvokeMember(null, BindingFlags.Public | BindingFlags.Instance | BindingFlags.CreateInstance, null, null, null); callerType.InvokeMember( methodName, BindingFlags.InvokeMethod, null, obj, //this created whole new menu! new Object[] { menuItemMRU, e }); //sender need to be menuItem

Error oops this creates a entire new object, in this case a new menu.

6th attempt - working properly. Perhaps read the MS doc first. 

1 2 3 4 5 6 7

this.GetType().InvokeMember( methodName, BindingFlags.InvokeMethod | BindingFlags.Instance, null, this, //<-THIS indicatates it being called by this program, class instantiation new object[] { menuItemMRU, e } //args to pass, we are faking a menu-item );
