C＃使用不同形式的類中的類

Question

我剛剛開始使用C＃和一個Windows窗體應用程序。我對OOP也相當陌生。我試圖創建一個應用程序，用戶可以在其中修改某些設置，然後打開第二個窗體。我找到了一種方法，使用額外的「設置類」將用戶輸入數據從「設置表單」移動到主表單。但我不確定我是否以良好的方式做這件事，並正在尋求有關最佳實踐的建議。

我對「主表」的代碼如下所示：

namespace Scheduler 
{ 
    public partial class FormScheduler : Form 
    { 

     public FormScheduler() 
     { 
      InitializeComponent(); 
     } 

     private PeriodSettings mPeriodSettings = new PeriodSettings(); 

     public string StartDate 
     { 
      get{ return mPeriodSettings.StartDate; } 

      set{ mPeriodSettings.StartDate = value; } 
     } 

     private void settingsSchPer_Click(object sender, EventArgs e) 
     { 
      FormSchemaPeriodSettings formSchPer = new FormSchemaPeriodSettings(); 
      formSchPer.formScheduler = this; 
      formSchPer.Show(); 
     } 

    } 
} 

而對於代碼「設置形成」看起來像：

namespace Scheduler 
{ 
    public partial class FormSchemaPeriodSettings : Form 
    { 

     public FormSchemaPeriodSettings() 
     { 
      InitializeComponent(); 
     } 

     public FormScheduler formScheduler = new FormScheduler(); 

     private void buttonCancel_Click(object sender, EventArgs e) 
     { 
      this.Close(); 
     } 

     private void buttonOK_Click(object sender, EventArgs e) 
     { 
      this.formScheduler.StartDate = this.startDate.Value.ToShortDateString(); 
      this.Close(); 
     } 
    } 
} 

例如，我必須定義properity爲SetDate在「主窗體」中，即部分

public string StartDate 
{ 
    get{ return mPeriodSettings.StartDate; } 

    set{ mPeriodSettings.StartDate = value; } 
} 

爲了能夠訪問類的StartDate的PeriodSettings或有沒有辦法能夠直接訪問已經定義的mPeriodSettings.StartDate？

我PeriodSettings類的樣子：

namespace Scheduler 
{ 
    class PeriodSettings 
    { 
     private string mStartDate; 
     private string mEndDate; 

     public PeriodSettings() 
     { 

     } 

     public string StartDate 
     { 
      get{ return mStartDate; } 

      set{ mStartDate = value; } 
     } 

     public string EndDate 
     { 
      get{ return mEndDate; } 

      set{ mEndDate = value; } 
     } 
    } 
} 

感謝任何意見！

你也可以打開設置表單作爲對話框，並用DialogResult屬性的工作，像這樣：

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

    public string StartDate 
    { 
     get { return mPeriodSettings.StartDate; } 
     set { mPeriodSettings.StartDate = value; } 
    } 

    private void settingsSchPer_Click(object sender, EventArgs e) 
    { 
     FormSchemaPeriodSettings formSchPer = new FormSchemaPeriodSettings(); 
     if (formSchPer.ShowDialog() == DialogResult.OK) 
      StartDate = formSchPer.ResultDate; 
    } 
} 

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

    public string ResultDate; 

    private void buttonCancel_Click(object sender, EventArgs e) 
    { 
     Close(); 
    } 

    private void buttonOK_Click(object sender, EventArgs e) 
    { 
     DialogResult = DialogResult.OK; 
     ResultDate = startDate.ValueToShortDateString(); 
     Close(); 
    } 
}
