C#의 양식에서 임의의 개체를 변경 한 후에 Visual Studio 2017에서 공용 정적 진술을 "공개"로 변경하는 이유

Question

내 코드를 게시했습니다. 매번 C#의 내 Windows Forms App에서이 양식의 내용을 변경하면 결국 "public static"변경 사항이 "public"으로 변경된 다음 "this"가 추가됩니다. 그 (것)들에 각 단일 참조에. 내 코드는 다시 편집 한 후에 정상적으로 실행되는 것처럼 보이지만 실제로는 성가시다. 나는 단지 내가 뭔가를 놓치지 않거나 이것에 대해 가난한 접근법을 취하지 않고 있는지 확인하고 싶었다.

공공 정적 문장을 사용하는 이유는 다른 양식에서 내 기본 양식의 일부 Textbox 및 DataGridView 개체를 수정하기 때문입니다. 즉, 한 양식의 데이터베이스에서 고객 정보를 찾고 기본 양식을 작성하고 한 장의 WebBrowser 컨트롤에서 장바구니 정보를 가져 와서 다른 양식의 DataGridView 개체에 넣습니다. 이것이 다른 양식에서 양식을 채우는 방법이 아니라면 C#을 처음 접했을 때 어떻게 구체적이고 구체적인지 알려주십시오. 미안 내가 너무 많은 코드를 게시 한 경우 - 이것은 내 form1.cs 파일의 거의 전부이며 내가 여기에있는 것이 무엇이 문제를 일으키는 지 알지 못했습니다. 관련 "공개 정적"진술은 결국 있습니다.

(이 글을 읽은 후에 누군가가 폼이 "특정 인스턴스화"라고되어있는 다른 스레드를 찾아 보았습니다. 그래서 개발자 환경은 "정적"을 계속 가져옵니다). 그럴 경우 ... 도움이됩니다! 한 양식의 값을 다른 양식에서 변경하는 방법을 이해하지 못하고 절대적으로 그렇게해야합니다. -이 코드는 작동하지만 나쁜 습관이라고 생각합니다. - 완전히 분실되어이 작업을하기 위해 매우 구체적인 지침이 필요함)

주의 깊게 자동 디자이너에 의해 생성되는이 작은 코멘트 기본적으로

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

코드의 일부를 발견하고 수정해서는 안됩니다 수동으로.

네, 이것은 나쁜 관행으로 간주됩니다. 첫째, 컨트롤은 정적 인 것이 아니라 폼 내부에 포함되어야합니다. Static은 동일한 클래스의 모든 양식에서 인스턴스가 하나만 존재한다는 것을 의미합니다.

한 양식에서 다른 양식으로 UI를 직접 수정하는 것도 안티 패턴으로 간주됩니다. 데이터 모델을 만들고 변경된 UI가 업데이트 된 데이터를 읽도록해야합니다. 나는 이것이 초보자들에게도 winform을 위해 조금 도전적일지도 모른다는 것을 안다.

따라서 바로 가기를 사용하려면 다른 양식의 공용 속성을 노출 할 수 있으며 속성을 수정하면 다른 양식이 해당 컨트롤을 업데이트합니다.

편집 : 뒤에 다른 형태의 코드 (.cs 파일)에서

당신이

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

    public string SelectedUser { get; private set; } 
} 

과 같이 할 수는 다음의 주요 형태로는 close 이벤트

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

을들을 것

...

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

    //do something 
}
