How to check the last character of a string in C#?

Question

I want to find the last character of a string and then put in an if stating that if the last character is equal to "A", "B" or "C" then to do a certain action. How do I get the last character?

Answer 1

Use the endswith method of strings:

if (string.EndsWith("A") || string.EndsWith("B")) {     //do stuff here } 

Heres the MSDN article explaining this method:

Answer 2

I assume you don't actually want the last character position (which would be yourString.Length - 1), but the last character itself. You can find that by indexing the string with the last character position:

yourString[yourString.Length - 1]
