示例

下面的示例调用 GetVersionInfo 来获取“记事本”(Notepad) 的 FileVersionInfo。然后，它在文本框内显示布尔值 IsPatched 的状态。这段代码假定已经实例化 textBox1。

Private Sub GetIsPatched()
    ' Get the file version for the notepad.
    Dim myFileVersionInfo As FileVersionInfo = _
        FileVersionInfo.GetVersionInfo("%systemroot%\Notepad.exe")
    
    ' Print whether the file has a patch installed.
    textBox1.Text = "File has patch installed: " & myFileVersionInfo.IsPatched
End Sub 'GetIsPatched

private void GetIsPatched() {
    // Get the file version for the notepad.
    FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo("%systemroot%\\Notepad.exe");
 
    // Print whether the file has a patch installed.
    textBox1.Text = "File has patch installed: " + myFileVersionInfo.IsPatched;
 }
    

private:
   void GetIsPatched()
   {
      // Get the file version for the notepad.
      FileVersionInfo^ myFileVersionInfo = FileVersionInfo::GetVersionInfo( "%systemroot%\\Notepad.exe" );
      
      // Print whether the file has a patch installed.
      textBox1->Text = String::Concat( "File has patch installed: ", myFileVersionInfo->IsPatched );
   }

private void GetIsPatched()
{
    // Get the file version for the notepad.
    FileVersionInfo myFileVersionInfo = 
        FileVersionInfo.GetVersionInfo("%systemroot%\\Notepad.exe");

    // Print whether the file has a patch installed.
    textBox1.set_Text("File has patch installed: " 
        + myFileVersionInfo.get_IsPatched());
} //GetIsPatched

private function GetIsPatched() {
    //Get the file version for the notepad.
    var myFileVersionInfo : FileVersionInfo = FileVersionInfo.GetVersionInfo("%systemroot%\\Notepad.exe");
 
    //Print whether the file has a patch installed.
    textBox1.Text = "File has patch installed: " + myFileVersionInfo.IsPatched;
 }
