SortByName() BubbleSort String Array

Sprache: C#

SortByName() is a BubbleSort Algorithm to sort the StringArray content alphabetically. It uses the String Method CompareTo(). This method compares the ASCII numbers and returns 1 if the name is "higher" and swaps it with the compared name, 0 if it´s equal and -1 if it´s lower, which means sorted in this case. It is implemented as a class method for class-intern string arrays. Here is some sampledata for your Program Main() to see how this is working: [code]Snippet snip = new Snippet(); snip.StringArray = new string[5]; snip.StringArray[0] = "A"; snip.StringArray[1] = "C"; snip.StringArray[2] = "Z"; snip.StringArray[3] = "I"; snip.StringArray[4] = "B"; snip.ShowAll(); snip.SortByName(); snip.ShowAll(); Console.ReadKey();[/code]

class Snippet
    {
        // Your class string Array. You need it to get this running.
        public string[] StringArray {get; set;}

        
        // SortByName() is a BubbleSort Algorithm to sort the Person names alphabetically.
