Error Converting String to Integer

Question

Why does the below code throw a System.FormatException -

Input string was not in a correct format

decimal sum = 0;
string valString = "3.5";

sum += Convert.ToInt32(valString);

Well, 3.5 is not a correct integer value (please, notice fraction part - .5), it's decimal in the context:

decimal sum = 0;
string valString = "3.5";

sum += Convert.ToDecimal(valString);

So dumb I didn't think that! I did do a ToDecimal but couldn't get to understand why ToInt didnt work. Thanks a ton for your answer!

Please try this:

sum += System.Convert.ToDecimal(valString);
