This works:

int val = Convert.ToInt32("1");

But this doesn't:

int val = Convert.ToInt32('1'); // returns 49

Shouldn't this convert to actual int?

Answer 1

It is returning the ASCII value of character 1

The first statement treats the argument as string and converts the value into Int, The second one treats the argument as char and returns its ascii value

Answer 2

As the others said, Convert returns the ASCII code. If you want to convert '1' to 1 (int) you should use

int val = Convert.ToInt32('1'.ToString());
