示例

以下示例调用 GetVersionInfo 以获取 FileVersionInfo 记事本的 。 然后在文本框中显示此版本是否为预发行版本。 此代码假定 textBox1 已实例化。

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 );
    }

 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
