How to find last character of a string

str = str.Substring(str.Length - 1);

string sAllCharacter="abcdef....yz";
char cLastCharacter=sAllCharacter[sAllCharacter.Lenght-1];

output=z;

string inputString = "CodeProject";
string lastCharacter = inputString.Substring(inputString.Length - 1);

string inputText = "Example_10";
textBox1.Text = inputText.Remove(0,inputText.Length-1);
