How can I append some string to function name.

Question

I have a for loop which calls click event every time. I want to append some string to the function name. say, button_click then I want it to be Button_click1, Button_click2 etc..

I want to perform some operation on values 1, 2 etc.. Please suggest if there is any other way to access this information.

Thread can be the last option I would opt.

Answer 1

The other answers are more correct for my money, but If you really need string based invocation I think you'll need to use the Reflection classes.

String suffix = "_Click1";
Type myType = typeof(MyClass);
myType.InvokeMember("Button"+ suffix, 
            BindingFlags.DeclaredOnly | 
            BindingFlags.Public | BindingFlags.NonPublic | 
            BindingFlags.Instance | BindingFlags.InvokeMethod, null, yourButtonObject, null);

Answer 2

You can try to create a Button array in and then you can create an event for a click of any button in the array.

Than, You can use a for loop that closes over a variable containing the current index:

for(int i = 0; i < buttons.Length; i++)
{
    //it's important to have this; closing over the loop variable would be bad
    int index = i;  
    buttons[i].Click += (sender, args) => SomeMethod(buttons[index], index);
}

This probably would be going to save a lot lines of code and easier as well.

I think you should just put all buttons in a list like so:

List<Button> ButtonList = new List<Button>(){Button1, Button2};

And then just call Button_Click for each of those buttons like so:

Foreach(Button button in ButtonList)
    button.Button_Click(this, new EventArgs());
