Get Index from String Array [C#]

[Shaitan00]

Given an array [public string[] OptArr;] filled with Strings

I need a method that would allow me to give the string and have the function return the INDEX in the Array where that string is stored.

 

Any clues?

OptArr.IndexOf()

[Shaitan00]

OptArr does not have a .IndexOf property.

 

Currently I am using the usual For/If loops but this reduces performance when my arrays become large.

My bad - VB makes me lazy like that. try the System.Array class' IndexOf method :

string[] OptArr = {"one","two","three"};
int i;
i= System.Array.IndexOf(OptArr,"two");
