如何在 c# 中停止调用父方法的执行？

Question

The calling parent method:

public void Script()
{
    string str = "some text";
    var someText = !CheckStr(str);
    if (someText)
    {
        return;
    }

    str = "some other text";
    var someOtherText = !CheckStr(str);
    if (someOtherText)
    {
        return;
    }

    str = "some other other text";
    var someOtherOtherText = !CheckStr(str);
    if (someOtherOtherText )
    {
        return;
    }

    // ...continue
}

The method that is being called:

public bool CheckStr(string str)
{
    if (str == "error")
    {
        return false;
    }

    // ...additional checks

    return true;
}

Is there a way that if CheckStr() returns false that it also stops the Scripts() method from further executing?

Right now I have to do a bunch of if checks in the Script() method, it feels a bit like I'm repeating myself with the if statement doing the same thing after each CheckStr() . It would be better if the CheckStr() halts te execution of Script() . Is something like this possible?

Yes, you can throw a exception.

It will interrupt calling "parents" (and their "parents") until a execption-handler is somewhere (try-catch block). Just google for exception-throwing.
