Solution 1

Of course it will throw an exception. You have white space between each digit in the string. First remove the white space then use the int.TryParse to do your convertions.

No, there do not have any space between the digits. The problem is the digits is in not in ASCII. Please copy "３２８５" & "3285" these and paste to notepad. You will see the different.

Thanks

All is in the comment, the second 3285 is an integer made of digits, but the one is some unicode that look like digits but is not made of digits.
the "３" is coded in utf-8 as EF BC 93
the "２" is coded in utf-8 as EF BC 92
the "８" is coded in utf-8 as EF BC 98
the "５" is coded in utf-8 as EF BC 95

the "３" is also decoded as U+FF13 FULLWIDTH DIGIT THREE, which is not a digit from the C# point of view.

If this is typical of data you have to handle, you should convert unicode chars to traditional digits first.
