class Program    
{
    static void Main()
    {
        string[] a = new string[]
        {
            "Egyptian",
            "Indian",
            "American",
            "Chinese",
            "Filipino",
        };
        Array.Sort(a);
        foreach (string s in a)
        {
            Console.WriteLine(s);
        }
    }
}

Array.Sort also provides a Predicate-Overload. You can specify your sorting-behaviour there:

Array.Sort(myArray, (p, q) => p[0].CompareTo(q[0]));

You can also use LINQ to Sort your array:

string[] myArray = ...;
string[] sorted = myArray.OrderBy(o => o).ToArray();

LINQ also empoweres you to sort a 2D-Array:

string[,] myArray = ...;
string[,] sorted = myArray.OrderBy(o => o[ROWINDEX]).ThenBy(t => t[ROWINDEX]).ToArray();

The default sorting-behaviour of LINQ is also alphabetically. You can reverse this by using OrderByDescending() / ThenByDescending() instead.

Sounds like you just want to use the Array.Sort method.

Array.Sort(myArray)

There are many overloads, some which take custom comparers (classes or delegates), but the default one should do the sorting alphabetically (ascending) as you seem to want.
