	char[] MyCharArray = new char[3];
	MyCharArray[0] = 'a';
	MyCharArray[1] = 'b';
	MyCharArray[2] = 'c';
	ReturnString = new string(MyCharArray);	//Note do not add a terminating null, if you do it will be present as a 0x00 character at the end of the string! 

Convert Char To Character Value

	char MyChar = 'A';
	int MyInt = Convert.ToInt32(MyChar); 
	MyInt = MyInt - Convert.ToInt32('A');

or

	char MyChar = 'A';
	int MyInt = Convert.ToInt32(MyChar - 'A'); 

For each char in a string
