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

Question

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?

Are you trying to return from the function or terminate the process? — sinelaw

You can use return; to stop the execution path.

that won't "Carry on" to the lblOutput code (as OP mentioned in question).

@BradChristie think you misread like I did initially, the OP says the code currently does that, but they don't want it to.

Ah, touche. Yea, must be a) not enough coffee, or b) a confusing question. (I'm leaning more toward the former)

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; }

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.

Instead or return just do

if() { } else { }
