    short instruction

    hello,

    I'm new to c sharp and I have a small problem.
    I have an array A of 4 elements.
    I want to check if an element e is part of the array, and if so return the index of this element (which is always unique) and assign it to a variable v.
    What's the easiest and shortest way of doing this, in one line if possible ?
    Something like var v = A.findNext(a=> a == e);
    The problem is that A.findNext doesn't exist, and A.contains only returns a boolean.

    Thanks.

    There are multiple ways.

    Code:
    // List of Integers
    var A = List<int>;
    
    //Find position of the number 42
    int myIndex = A.IndexOf(42);
    
    //or
    
    int myIndex = A.FindIndex( (i) => i == 42 );
