Parsing/Converting String as INTEGER using C#

Parsing/Converting String as INT using C#

In this blog, we are going to parse the string to specific INT data Type.

Usage:

int a = TryParseInt("234", int.MinValue);//TRUE

int b = TryParseInt("2B4", int.MinValue);//False

Response.Write(string.Format("A:{0},B:{1}", a, b)+"<br/>");

 

OUTPUT:

A:234,B:-2147483648

 

Method1: int.TryParse

Best to use if there is uncertain about the input string.

     

///         /// Parses the string as Int.         /// It wont throw error. Instead it gives the ifFail value if error occurs         ///         public int TryParseInt(string input, int ifFail)         {             int output;               if (int.TryParse(input, out output))             {                 output = output;             }             else             {                 output = ifFail;             }               return output;         }

 

Method 2: int.Parse

If you sure about the input string going to be valid, then go for this method.

///         /// Parses the string as Int. But if Int string is invalid, then it throws error         ///         public int ParseInt(string input)         {             return int.Parse(input);         }
