Two interesting things about C# strings

1. Iterating with foreach

The String class implements the IEnumerable interface, so you can iterate over it using a foreach statement. Each iteration will yield subsequent characters from the string:

string myString =  "I'm out of the loop, and that's the way I like it";

foreach (char ch in myString)
{
    Console.WriteLine(ch);
}

2. The indexer

The String class provides an indexer, it returns a Char object that corresponds to the specified position of the string, for example:

string myString = "But it is, perhaps, the end of the beginning";

char first = myString[0]; // 'B'
char last  = myString[myString.Length - 1]; // 'g'
