How can I stop executing the rest of a method at some point inside the method?

I was wondering if there is a command which would have the same function as exit.

So, for instance:

if (Average < 35)
{
    MessageBox.Show("you failed");
    **EXIT**
}

if (Average >= 75)
{
    lblOutput.Text += Name +" " + Surname + ", " + "your average was: " + Average + ", you shall recieve a bursary!";
}
else
    lblOutput.Text += Name +" " + Surname + ", " + "your average was: " + Average + ", you shall not revieve a bursary!";

Even if the average is lower than 35, the script will carry on going and the lblOutput will still say You shall not receive a bursary. while it should just show the MessageBox and not do anything with the label.

Could someone explain how to do this?

Alternatively to using return to exit early, you could write your if statements in such a way that it naturally follows that code path

if (Average >= 75)
{
    lblOutput.Text += Name +" " + Surname + ", " + "your average was: " + Average + ", you shall recieve a bursary!";
}
else if (Average >= 35)
{
    lblOutput.Text += Name +" " + Surname + ", " + "your average was: " + Average + ", you shall not revieve a bursary!";
}
else
{
    MessageBox.Show("you failed");
}

For me this is better from a readability point of view.

if()
{
}

I suppose that current code reside in a method with return type void, you can simply use return;

if (Average < 35)
{
    MessageBox.Show("you failed");
    return;
}

You can use return; to stop the execution path.
