+Summary: Converting from base in System.Convert doesn't throw exception
+Description of Problem:
+When converting strings with for example Convert.ToInt32 from desired base 
+there can be an invalid string without FormatException. The specification 
+doesn't say anything about FormatException but csc throws FormatException 
+for this.
+Console.WriteLine(Convert.ToInt32("2", 2));
+Also if you put in a string in the wrong format for example "1239" to be 
+converted from base 8 it's interpreted as "1241".
+Steps to reproduce the problem:
+1. Run the code
+Console.WriteLine(Convert.ToInt32("1239", 8));
+Actual Results:
+Expected Results:
+How often does this happen? 
+All the time
+Additional Information:
+"1239" is interpreted as "1241" which would mean that the overflow from 
+the last digit (9) is added to the second last digit (3).
