BindingMemberInfo.BindingPath 属性

定义

命名空间:

System.Windows.Forms

程序集:

System.Windows.Forms.dll

获取数据绑定对象的属性名之前的属性名或句点分隔的属性名层次结构。

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

public string BindingPath { get; }

member this.BindingPath : string

Public ReadOnly Property BindingPath As String

属性值

String

数据绑定对象属性名之前的属性名或句点分隔的属性名层次结构。

示例

下面的代码示例获取BindingMemberInfo窗体上的每Binding一个，并输出和BindingMemberBindingPathBindingField属性值。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

注解

是BindingPath属性返回BindingMember的导航路径前面BindingField属性名称的句点分隔组合。 例如，如果创建了具有dataMember“Customers.custToOrders.OrderDate”参数的新Binding项，BindingPath将返回“Customers.custToOrders”。
