BindingMemberInfo.BindingPath 属性
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。
**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 BindingPath As String
用法
Dim instance As BindingMemberInfo
Dim value As String
value = instance.BindingPath
public string BindingPath { get; }
public:
property String^ BindingPath {
String^ get ();
}
/** @property */
public String get_BindingPath ()
public function get BindingPath () : String
属性值
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。
备注
BindingPath 是以句点分隔的属性名的组合,该组合在 BindingMember 属性返回的导航路径中位于 BindingField 之前。例如,如果创建了具有 dataMember 参数“Customers.custToOrders.OrderDate”的新 Binding,则 BindingPath 将返回“Customers.custToOrders”。
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
