C#, Convert.ToInt32(string) question

  I've got some C# code in an inherited application that is not working. The problem seems to be that the input is a string consisting of a decimal number. The code is trying to convert the string to an integer, using the following line
Convert.ToInt32(string)

   I did some searching and it seems that this method is expecting a whole number string, and won't work with a decimal number string. Is that correct? Is there an easy fix for this? I am expecting both whole numbers and decimal numbers as input here. Thanks for the help!

Yes, Convert.ToInt32(string) only works for integers.  Try Convert.ToDecimal(string) or Convert.ToDouble(string) if you expect decimal numbers.

You could ...

i = (Int32)Convert.ToDouble(your_string);

This is your best bet:

                    string a = "1.1";
                    decimal d = decimal.MinValue;
                    decimal.TryParse( a, out d );
