示例

下面的代码示例演示如何构造新的 BindingList<T>。 有关完整示例，请参阅 BindingList<T> 类概述主题。

// Declare a new BindingListOfT with the Part business object.
BindingList<Part> listOfParts;
void InitializeListOfParts()
{
    // Create the new BindingList of Part type.
    listOfParts = new BindingList<Part>
    {
        // Allow new parts to be added, but not removed once committed.        
        AllowNew = true,
        AllowRemove = false,

        // Raise ListChanged events when new parts are added.
        RaiseListChangedEvents = true,

        // Do not allow parts to be edited.
        AllowEdit = false
    };

    // Add a couple of parts to the list.
    listOfParts.Add(new Part("Widget", 1234));
    listOfParts.Add(new Part("Gadget", 5647));
}

' Declare a new BindingListOfT with the Part business object.
Private WithEvents listOfParts As BindingList(Of Part)

Private Sub InitializeListOfParts()

    ' Create the new BindingList of Part type.
    listOfParts = New BindingList(Of Part)

    ' Allow new parts to be added, but not removed once committed.        
    listOfParts.AllowNew = True
    listOfParts.AllowRemove = False

    ' Raise ListChanged events when new parts are added.
    listOfParts.RaiseListChangedEvents = True

    ' Do not allow parts to be edited.
    listOfParts.AllowEdit = False

    ' Add a couple of parts to the list.
    listOfParts.Add(New Part("Widget", 1234))
    listOfParts.Add(New Part("Gadget", 5647))

End Sub

参数

list
IList<T>

要包含在其中的项之IList<T>一BindingList<T>。

属性
RequiresUnreferencedCodeAttribute

注解

使用此 BindingList<T> 方法创建一个 BindingList<T> 受 list支持的对象，这可确保 list 更改反映在其中 BindingList<T>。
