Process c# winforms button as keystroke?

Question

I want to make a button on that when pressed, the key combination Ctrl + + is pressed and another where Ctrl + - is pressed. How

Answer 1

Here is a possible solution for what you want:

//Button creation
Button myButton= new Button();
myButton.Click += myButton_Click;

Then in the event myButton_Click();

void myButton_Click(object sender, EventArgs e)
{
    SendKeys.Send("^({ADD})")
}

You can then do similar for the - key, check here for the key symbols to use

EDIT

The other variation is to do this instead:

void myButton_Click(object sender, EventArgs e)
{
    SendKeys.Send("^({+})")
}

The plus sign (+), caret (^), percent sign (%), tilde (~), and parentheses () have special meanings to SendKeys. To specify one of these characters, enclose it within braces ({}). For example, to specify the plus sign, use "{+}".
