Question

I have a list of methods I wish to call and a button accompaning each and a generic method to handle the buttons.

Using the commandArgument how can I run the selected method.

E.g. Click run method1 button. In handler for button click call the method as named in commandArgument

Answer 1

So the string in the CommandArgument matches the name of a method? If you must do this then you could use reflection. I’m assuming you’ve basically got a single button click event for each button or you wouldn’t be asking this:

private void MethodA() { }

protected void Button_Click(object sender, EventArgs e)
{
    string arg = ((Button)sender).CommandArgument;  // = MethodA
    MethodInfo method = this.GetType().GetMethod(arg);
    method.Invoke(this, null);
}

Although this looks like a massive code smell. Why do you have to do it this way? Why can you not just give each button a separate event handler and call each method directly?

Alternatively, why not use a switch statement on the argument:

protected void Button_Click(object sender, EventArgs e)
{
    string arg = ((Button)sender).CommandArgument;  // = MethodA
    switch (arg)
    {
        case "MethodA":
            MethodA(); break;
        case "MethodB":
            MethodB(); break;
    }
}
