BindingMemberInfo.BindingMember 屬性

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

取得資訊，用於指定資料繫結物件的屬性名稱。

public:
 property System::String ^ BindingMember { System::String ^ get(); };

public string BindingMember { get; }

member this.BindingMember : string

Public ReadOnly Property BindingMember As String

屬性值

String

空字串 ("")、單一屬性名稱或句號分隔的屬性名稱階層架構，解析為最終資料繫結物件的屬性名稱。

範例

下列程式碼範例會取得 BindingMemberInfo 表單上每個 Binding 物件，並列印 BindingPath 的 、 BindingField 和 BindingMember 屬性值 BindingMemberInfo 。

private:
   void PrintBindingMemberInfo()
   {
      Console::WriteLine( "\n BindingMemberInfo" );
      for each ( Control^ thisControl in this->Controls )
      {
         for each ( Binding^ thisBinding in thisControl->DataBindings )
         {
            BindingMemberInfo bInfo = thisBinding->BindingMemberInfo;
            Console::WriteLine( "\t BindingPath: {0}", bInfo.BindingPath );
            Console::WriteLine( "\t BindingField: {0}", bInfo.BindingField );
            Console::WriteLine( "\t BindingMember: {0}", bInfo.BindingMember );
            Console::WriteLine();
         }
      }
   }

private void PrintBindingMemberInfo()
{
   Console.WriteLine("\n BindingMemberInfo");
   foreach(Control thisControl in this.Controls)
   {
      foreach(Binding thisBinding in thisControl.DataBindings)
      {
         BindingMemberInfo bInfo = thisBinding.BindingMemberInfo;
         Console.WriteLine("\t BindingPath: " + bInfo.BindingPath);
         Console.WriteLine("\t BindingField: " + bInfo.BindingField);
         Console.WriteLine("\t BindingMember: " + 
         bInfo.BindingMember);
         Console.WriteLine();
      }   
   }
}

Private Sub PrintBindingMemberInfo()
   Console.WriteLine(ControlChars.Cr + " BindingMemberInfo")
   Dim thisControl As Control
   Dim thisBinding As Binding
   For Each thisControl In  Me.Controls    
      For Each thisBinding In  thisControl.DataBindings
         Dim bInfo As BindingMemberInfo =  _
         thisBinding.BindingMemberInfo
         Console.WriteLine(ControlChars.Tab + _
         " BindingPath: "  + bInfo.BindingPath)
         Console.WriteLine(ControlChars.Tab + _
         " BindingField: " + bInfo.BindingField)
         Console.WriteLine(ControlChars.Tab + _
         " BindingMember: "  + bInfo.BindingMember)
         Console.WriteLine()
      Next thisBinding
   Next thisControl
End Sub

備註

BindingMemberInfo當您使用 control-property name、資料來源和導覽路徑呼叫 BindingMemberInfo 建構函式時，會自動建立 。 參數 dataMember 包含 BindingMember 字串。

BindingMember是 和 BindingField 值的句點分隔組合 BindingPath 。 例如，使用 dataMember 「Customers.custToOrders.OrderDate」 的參數建立新的 Binding 時， BindingMember 會傳回 「Customers.custToOrders.OrderDate」。
