The following example calls GetVersionInfo to get the FileVersionInfo for the Notepad. Then it displays whether this version is a prerelease version in a text box. This code assumes textBox1 has been instantiated.
private:
void GetIsPreRelease()
{
// Get the file version for the notepad.
FileVersionInfo^ myFileVersionInfo =
FileVersionInfo::GetVersionInfo( Environment::SystemDirectory + "\\Notepad.exe" );
// Print whether the file is a prerelease version.
textBox1->Text = String::Concat( "File is prerelease version ", myFileVersionInfo->IsPreRelease );
}
C#
private void GetIsPreRelease()
{
// Get the file version for the notepad.
FileVersionInfo myFileVersionInfo =
FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\\Notepad.exe");
// Print whether the file is a prerelease version.
textBox1.Text = "File is prerelease version " + myFileVersionInfo.IsPreRelease;
}
Private Sub GetIsPreRelease()
' Get the file version for the notepad.
Dim myFileVersionInfo As FileVersionInfo = _
FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\Notepad.exe")
' Print whether the file is a prerelease version.
textBox1.Text = "File is prerelease version " & myFileVersionInfo.IsPreRelease
End Sub
