C＃でフォーム上の任意のオブジェクトのアスペクトを変更した後に、Visual Studio 2017がパブリック静的ステートメントを「パブリック」に変更し続けるのはなぜですか？

Question

コードを投稿しました。私のWindowsフォームアプリケーションでC＃のフォームを変更するたびに、 "public static"変更が最後に "public"に変更され、 "this"が追加されます。それらへのすべての単一の参照に。私のコードはもう一度編集した後に正常に動作するようですが、これは本当に面倒です。私はちょうど私が何かを逃していないか、これに貧弱なアプローチをしていないことを確認したかった。

パブリック静的ステートメントを使用しているのは、主フォームの一部のテキストボックスとDataGridViewオブジェクトを他のフォームから変更しているためです。つまり、あるフォームのデータベースから顧客情報を検索し、 1つのフォーム上のWebBrowserコントロールからショッピングカート情報を取得し、別のフォーム上のDataGridViewオブジェクトに入れます。これが、別のフォームからフォームを入力する方法ではない場合は、C＃の新機能として、どのようにして具体的な方法を教えてください。申し訳ありませんが、あまりにも多くのコードを投稿した場合 - これは私のform1.csファイルからほとんどすべてですが、私はここに何が（もしあれば）問題を引き起こしているのか分かりませんでした。関連する「パブリック静的」ステートメントは最後にあります。

（私はこれを後にしました。誰かがフォームが「特定のインスタンス化」であると言われた別のスレッドを調べました。そのため、開発環境は「静的」なままです）。それが事実です...助けて！私はあるフォームの値を別のフォームから変更する方法を理解しておらず、絶対にそうする必要があります。 - このコードは機能しますが、悪い習慣だと思いますか？ - 完全に失われ、この作業を行うための具体的な指示が必要）

Answer 1

慎重にあなたは自動デザイナーによって生成され、この小さなコメント基本的に

/// <summary> 
    /// Required method for Designer support - do not modify 
    /// the contents of this method with the code editor. 
    /// </summary> 

コードのその部分に気づくでしょうし、修正すべきではありません手動で

はい、これは悪い習慣とみなされます。まず、コントロールはスタティックなものではなくフォームの内部に含まれていなければなりません。 Staticは、同じクラスのすべてのフォームに1つのインスタンスしか存在しないことを意味します。

あるフォームから別のフォームへのUIの直接修正も同様にアンチパターンとみなされます。データモデルを作成し、変更されたときに更新されたデータをUIに読み込ませる必要があります。私はこれが初心者のためだけでなく、winformのために少し挑戦かもしれないことを知っています。

したがって、ショートカットを使用する場合は、他のフォームのパブリックプロパティを公開することができます。プロパティを変更すると、他のフォームが適切なコントロールを更新します。

編集：背後にある他のフォームのコードで （ファイル.csファイル）

あなたは

public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 
    } 

    public string SelectedUser { get; private set; } 
} 

のように行うことができ、その後、あなたのメインフォームであなたが近いイベント

Form1 other = new Form1(); 
    other.FormClosed += Other_FormClosed; 
    other.Show(); 

に耳を傾けるだろう

...

private void Other_FormClosed(object sender, FormClosedEventArgs e) 
{ 
    Form1 other = (Form1)sender; 
    string selectedUser = other.SelectedUser; 

    //do something 
}
