You can actually just use the Remove overload that takes one parameter   str   str Remove str Length - 3     However  if you re trying to avoid hard coding the length  you can use   str   str Remove str IndexOf

This will return to you a string excluding everything after the comma  str   str Substring 0  str IndexOf          Of course  this assumes your string actually has a comma with decimals   The above code will fail if it doesn t   You d want to do more checks   commaPos   str IndexOf       if commaPos    -1      str   str Substring 0  commaPos    I m assuming you re working with a string to begin with   Ideally  if you re working with a number to begin with  like a float or double  you could just cast it to an int  then do myInt ToString   like   myInt    int double Parse myString    This parses the double using the current culture  here in the US  we use   for decimal points    However  this again assumes that your input string is can be parsed

You could use LastIndexOf and Substring combined to get all characters to the left of the last index of the comma within the sting   string var   var Substring 0  var LastIndexOf

Use   public static class StringExtensions            lt summary gt          Cut End   12  SubstringFromEnd 1  - gt   1           lt  summary gt      public static string SubstringFromEnd this string value  int startindex                if  string IsNullOrEmpty value   return value          return value Substring 0  value Length - startindex             I prefer an extension method here for two reasons    I can chain it with Substring    Example  f1 Substring directorypathLength  SubstringFromEnd 1  Speed

String Format   0 0    123 4567            123    If your initial value is a decimal into a string  you will need to convert  String Format   0 0    double Parse  3 5   CultureInfo InvariantCulture      3 5   In this example  I choose Invariant culture but you could use the one you want   I prefer using the Formatting function because you never know if the decimal may contain 2 or 3 leading number in the future    Edit  You can also use Truncate to remove all after the   or    Console WriteLine Decimal Truncate Convert ToDecimal  3 5
