∟Creating FileVersionInfo Objects

This section provides a tutorial example on how to create a FileVersionInfo object to represent the version information of a specific executable file.

If you read the reference of FileVersionInfo class, you will see no constructor method provided in the FileVersionInfo class.

Without a constructor method, how can you create a FileVersionInfo object? The answer is to use the static method called GetVersionInfo().

GetVersionInfo(fileName) is a static method that returns a FileVersionInfo object representing the version information stored with the specified file. "fileName" is a string representation of the path name of the specified file.

Here is a quick sample C# program that shows you how to use the FileVersionInfo.GetVersionInfo() static method.

// FileVersionInfoTest.cs
// Copyright (c) 2016 HerongYang.com. All Rights Reserved.

using System;
using System.Diagnostics;
public class FileVersionInfoTest {
   public static void Main() {

      // Creating the FileVersionInfo object to represent cmd.exe
      FileVersionInfo cmdVersion
         = FileVersionInfo.GetVersionInfo("C:\\Windows\\System32\\cmd.exe");

      // Printing out version information of cmd.exe
      Console.WriteLine();
      Console.WriteLine("File name: {0}", cmdVersion.FileName);
      Console.WriteLine("File description: {0}",
         cmdVersion.FileDescription);
      Console.WriteLine("File version: {0}", cmdVersion.FileVersion);
   }
}

Compile it with .NET SDK 4.6.1 and run it:

C:\herong>\windows\Microsoft.NET\Framework\v4.0.30319\csc
   FileVersionInfoTest.cs

C:\herong>FileVersionInfoTest.exe

File name: C:\Windows\System32\cmd.exe
