public ref class FileVersionInfo sealed
public sealed class FileVersionInfo
type FileVersionInfo = class
Public NotInheritable Class FileVersionInfo
Inheritance
FileVersionInfo

Examples

The following example calls GetVersionInfo to get the FileVersionInfo for the Notepad. Then it prints the file description and version number to the console.

#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:

Use the GetVersionInfo method of this class to get a FileVersionInfo containing information about a file, then look at the properties for information about the file. The FileVersion property provides version information about the file. The ProductMajorPart, ProductMinorPart, ProductBuildPart, ProductPrivatePart, and ProductVersion properties provide version information for the product that the specified file is a part of. Call ToString to get a partial list of properties and their values for this file.

The FileVersionInfo properties are based on version resource information built into the file. Version resources are often built into binary files such as .exe or .dll files; text files do not have version resource information.

Version resources are typically specified in a Win32 resource file, or in assembly attributes. For example the IsDebug property reflects the VS_FF_DEBUG flag value in the file's VS_FIXEDFILEINFO block, which is built from the VERSIONINFO resource in a Win32 resource file. For more information about specifying version resources in a Win32 resource file, see "About Resource Files" and "VERSIONINFO Resource" in the Platform SDK. For more information about specifying version resources in a .NET module, see the Setting Assembly Attributes topic.

Note

This class makes a link demand at the class level that applies to all members. A SecurityException is thrown when the immediate caller does not have full trust permission. For details about link demands, see Link Demands.
