Renaming a button from a string

Question

I am trying to rename a button from a string. Sounds simple enough? Well I have scowered the internet and tried many things however I keep coming up with the same errors.

I have 2 forms and one class file. I am using object orientation to pass a string from a textbox to form1 where upon the "button1.Text" can be change passing it through my "Reference class" (I don't think it can be done any other way)

    private void button1_Click_1(object sender, EventArgs e)
    {
        Refclass Ref = new Refclass();
        String but1 = Ref.but1;

        String btn = "button1"; this.Controls[btn].Text = but1;
    }

I am sure this is probably wrong but I hope by this might be able to understand what I am trying to do. I am calling a string from the "Ref" class and calling the string "hell"

Needless to say I am either getting a debugging error and totally crashing visual studio or I get an error saying "Object reference not set to an instance of an object."

I know I am going wrong somewhere does anyone know where? Thank you.

Answer 1

there is no need of create the object for class.if your class in same assembly.just call like this.

button1.text=ref.but1;

where but1 is a const string in that class.
