Examples

The following example calls GetVersionInfo to get the FileVersionInfo for the Notepad. Then it prints the file description and version number in a text box. This code assumes textBox1 has been instantiated.

#using <System.dll>

using namespace System;
using namespace System::IO;
using namespace System::Diagnostics;


public ref class Class1
{
    
public:
    static void Main()
    {
        // Get the file version for the notepad.
        // Use either of the two following methods.
        FileVersionInfo::GetVersionInfo(Path::Combine(Environment::SystemDirectory, "Notepad.exe"));
        FileVersionInfo^ myFileVersionInfo = FileVersionInfo::GetVersionInfo(Environment::SystemDirectory + "\\Notepad.exe");


        // Print the file name and version number.
        Console::WriteLine("File: " + myFileVersionInfo->FileDescription + "\n" +
           "Version number: " + myFileVersionInfo->FileVersion);
    }
};

int main()
{
    Class1::Main();
}


using System;
using System.IO;
using System.Diagnostics;

class Class1
{
    public static void Main(string[] args)
    {
        // Get the file version for the notepad.
        // Use either of the two following commands.
        FileVersionInfo.GetVersionInfo(Path.Combine(Environment.SystemDirectory, "Notepad.exe"));
        FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\\Notepad.exe");

        // Print the file name and version number.
        Console.WriteLine("File: " + myFileVersionInfo.FileDescription + '\n' +
           "Version number: " + myFileVersionInfo.FileVersion);
    }
}

Imports System.IO
Imports System.Diagnostics



Class Class1

    Public Shared Sub Main(ByVal args() As String)
        ' Get the file version for the notepad.
        ' Use either of the following two commands.
        FileVersionInfo.GetVersionInfo(Path.Combine(Environment.SystemDirectory, "Notepad.exe"))
        Dim myFileVersionInfo As FileVersionInfo = FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\Notepad.exe")


        ' Print the file name and version number.
        Console.WriteLine("File: " + myFileVersionInfo.FileDescription + vbLf + "Version number: " + myFileVersionInfo.FileVersion)

    End Sub
End Class

Remarks

Typically, a version number is displayed as "major number.minor number.build number.private part number". A file version number is a 64-bit number that holds the version number for a file as follows:

The first 16 bits are the FileMajorPart number.
The next 16 bits are the FileMinorPart number.
The third set of 16 bits are the FileBuildPart number.
The last 16 bits are the FilePrivatePart number.
