BindingMemberInfo.BindingField 屬性

定義

命名空間:

System.Windows.Forms

組件:

System.Windows.Forms.dll

取得資料繫結物件的屬性名稱。

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

public string BindingField { get; }

member this.BindingField : string

Public ReadOnly Property BindingField As String

屬性值

String

資料繫結物件的屬性名稱。 這個值不能是空字串 ("")。

範例

下列程式碼範例會取得 BindingMemberInfo 表單上每個 Binding 的 ，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

BindingField是 屬性所 BindingMember 傳回之導覽路徑中最後一個專案。 例如，如果建立新的 Binding ，且其參數為 dataMember 「Customers.custToOrders.OrderDate」， BindingMember 將會傳回 「OrderDate」。
