See more:

if (e.Control && e.KeyCode == Keys.D2)
          {

              textBox1.Text="2";
          }
           {

I want

if (e.Control && e.KeyCode == Keys.D2)

only to happen if textbox1.Text = "test".

How can I do this
This is very new to me, sorry

Solution 1

You can just add a third condition:

C#

if (textBox1.Text.Equals("test") && e.Control && e.KeyCode == Keys.D2)
{
   // ...
}

Or you can nest if blocks:

C#

if (textBox1.Text.Equals("test"))
{
   if (e.Control && e.KeyCode == Keys.D2)
   {
      // ...
   }
}

Solution 2

C#

if (textBox1.Text == "test")
   {
   if (e.Control && e.KeyCode == Keys.D2)
      {
      textBox1.Text="2";
      }
   }

Or

C#

if (textBox1.Text == "test" && e.Control && e.KeyCode == Keys.D2)
   {
   textBox1.Text="2";
   }

First day learning c#? ;)

As previously stated; you could either compound the IF statements into one or nest them

C#

// compounded
if (e.Control) && e.KeyCode == Keys.D2 && textbox1.Text == "test" ) {
	textBox1.Text="2";
}
// nested
if (e.Control) && e.KeyCode == Keys.D2) {
	if (textbox1.Text == "test" ) {
		textBox1.Text="2";
	}
}

Now one thing about the nested version is this could be further expanded if you had to add in various renditions of the third condition

C#

if (e.Control) && e.KeyCode == Keys.D2) {
	if (textbox1.Text == "test" ) { textBox1.Text="2"; }
	if (textbox1.Text == "exam" ) { textBox1.Text="3"; }
}

Or if there would be a bunch of textbox1.Text values to check, you could utilize a switch...case block

C#

if (e.Control) && e.KeyCode == Keys.D2) {
	switch(textbox1.Text) {
		case "test":
			textBox1.Text="2";
			break;
		case "exam":
			textBox1.Text="3";
			break;
		case "quiz":
		case "check":
			textBox1.Text = "4";
			break;
		default:
			textBox1.text = "0"
			break;
	}	
}

Please note that all of these comparisons are case-sensitive by default
