Strange scenario Convert.ToChar(integer) or (char)integer

Question

I have the following condition.

Console.WriteLine(Convert.ToChar(65)); // Gives 'A'

Console.WriteLine(Convert.ToChar(65) + 1); // Gives 66; Expectation was 'A1'

Console.WriteLine(Convert.ToChar(65) + "1"); // Gives 'A1'

Why is that? I wanted the 3rd case.

Answer 1

Reason you are getting 66 instead of A1 is because you are adding a char to an integer. If you add a string to char, only then it will return you a string.

documentation on char The char keyword is used to declare an instance of the System.Char structure that the .NET Framework uses to represent a Unicode character. The value of a Char object is a 16-bit numeric (ordinal) value
