How can I find out whether two arrays of string are equal to each other?

I used this, but it does not work, even though the contents of both are the same.

string[] array1 = new string[]{"A" , "B"}

string[] array2 = new string[]{"A" , "B"}

if(array1 == array2)  // it return false !!!!
{
  // 
}

If you have access to Linq, use SequenceEqual. Otherwise, simply provide the code to first check if the arrays are equal length, and then if items are equal at each index.
