BindingMemberInfo.BindingField 属性

获取数据绑定对象的属性名。

**命名空间:**System.Windows.Forms
**程序集:**System.Windows.Forms（在 system.windows.forms.dll 中）

语法

声明
Public ReadOnly Property BindingField As String
用法
Dim instance As BindingMemberInfo
Dim value As String

value = instance.BindingField

public string BindingField { get; }

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

/** @property */
public String get_BindingField ()

public function get BindingField () : String

属性值

数据绑定对象的属性名。这可以是一个空字符串 ("")。

备注

BindingField 是 BindingMember 属性返回的导航路径中的最后一项。例如，如果创建了具有 dataMember 参数“Customers.custToOrders.OrderDate”的新 Binding，则 BindingMember 将返回“OrderDate”。

示例

下面的代码示例获取窗体上每个 Binding 的 BindingMemberInfo，并输出 BindingMemberInfo 的 BindingPath、BindingField 和 BindingMember 属性值。

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

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:
   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");
    for (int iCtr1 = 0; iCtr1 < this.get_Controls().get_Count(); iCtr1++) {
        Control thisControl = this.get_Controls().get_Item(iCtr1);
        for (int iCtr2 = 0;
            iCtr2 < thisControl.get_DataBindings().get_Count(); iCtr2++) {
            Binding thisBinding = 
                thisControl.get_DataBindings().get_Item(iCtr2);
            BindingMemberInfo bInfo = thisBinding.get_BindingMemberInfo();
            Console.WriteLine(("\t BindingPath: " 
                + bInfo.get_BindingPath()));
            Console.WriteLine(("\t BindingField: "  
                + bInfo.get_BindingField()));
            Console.WriteLine(("\t BindingMember: "  
                + bInfo.get_BindingMember()));
            Console.WriteLine();
        }
    }
} //PrintBindingMemberInfo
