私はWPFGinectプロジェクトに取り組んでいます。これは、Windows Kinectの開発者ツールキットサンプルの1つであり、「Kinectエクスプローラー」と呼ばれます。Kinect Developer Toolkit SDKver1.5からダウンロードできます。kinectwindow.xamlに、ボタンとチェックボックスを追加しました。また、kinectskeleton.csというクラスがあり、2つのDataTableとブール変数を作成しました。最初DataTableのものはOnRender関数に入力され、もう1つは空です。ブール変数はデフォルトでfalseに設定されています。だから、私が欲しいのは、kinectwindow.xaml.csのボタンが押されたときに、塗りつぶされた最新のデータがDataTable空のデータにコピーされることです。次に、チェックボックスをオンにすると、ブール値がtrueに設定されます。だから、これを行う方法は？
kinectskeleton.csクラスで、データを塗りつぶしから空にコピーする関数を定義しましたDataTable。kinectwindow.xaml.csのボタンのOnClick関数で、クラスからオブジェクトを作成してkinectskeletonこの関数を呼び出しましたが、両方のDataTableが空です。関数のチェックボックスについても同じですCheckBox_Checked。クラスのブール値kinectskeltonをtrueに設定しました（チェックされていない関数ではfalseに設定しました）。しかし、その結果、kinectskeltonクラスでは常にデフォルト値（false）に設定され、trueのときに入力するように作成したif条件には決して入りません。
それがより明確になり、提案を待っていることを願っています。ツールキットをダウンロードするには、次のリンクを参照してください：http: //www.microsoft.com/en-us/kinectforwindows/develop/developer-downloads.aspx
