C# Version TryParse

Description

Version TryParse tries to convert the string representation of a version number to an equivalent Version object, and returns a value that indicates whether the conversion succeeded.

Syntax

Version.TryParse has the following syntax.

public static bool TryParse(
  string input,
  out Version result
)

Parameters

Version.TryParse has the following parameters.

• input - A string that contains a version number to convert.
• result - When this method returns, contains the Version equivalent of the number that is contained in input, if the conversion succeeded, or a Version object whose major and minor version numbers are 0 if the conversion failed. If input is null or String.Empty, result is null when the method returns.

Returns

Version.TryParse method returns true if the input parameter was converted successfully; otherwise, false.

Example

The following example uses the TryParse method to parse a number of strings that contain version information.

// w  ww  .j ava 2s.  co m
using System;

public class Example
{
   public static void Main()
   {
      string input = "4.0";
      Version ver = null;
      if (Version.TryParse(input, out ver))
         Console.WriteLine("Converted '{0} to {1}.", input, ver);
      else
         Console.WriteLine("Unable to determine the version from '{0}'.",
                           input);
   }
}

The code above generates the following result.
