IHierarchyData.Type 속성

정의

Object 속성에 포함된 Item의 형식 이름을 가져옵니다.Gets the name of the type of Object contained in the Item property.

public:
 property System::String ^ Type { System::String ^ get(); };
public string Type { get; }
member this.Type : string
Public ReadOnly Property Type As String

속성 값

IHierarchyData 개체가 나타내는 개체의 형식 이름입니다.The name of the type of object that the IHierarchyData object represents.

예제

다음 코드 예제에서는 기본을 작성 하는 방법을 보여 줍니다 IHierarchyData 속성을는 HttpResponse 유형을 확인 한 다음 스트림는 IHierarchyData 를 사용 하 여 개체를 Type 속성과 자세한 형식별 작업을 수행 하려면 개체를 캐스팅 합니다.The following code example demonstrates how to write the basic IHierarchyData properties to an HttpResponse stream, then check the type of an IHierarchyData object using the Type property and cast the object to perform more type-specific operations. 이 코드 예제는에 대해 제공 된 큰 예제의 일부는 IHierarchyData 인터페이스입니다.This code example is part of a larger example provided for the IHierarchyData interface.

// Print out the current data node, then iterate through its
// children and do the same.
private void PrintFullChildNodeInfo(IHierarchyData node)
{
    string whitespace = "     ";
    string br = "<BR>";

    Response.Write(node.ToString() + br);
    Response.Write(whitespace + node.Path + br);

    // Check for specific types and perform extended functions.
    if (node.Type == "SiteMapNode")
    {
        // Because SiteMapNode implements the IHierarchyData interface,
        // the IHierarchyData object can be cast directly as a SiteMapNode,
        // rather than accessing the Item property for the object that
        // the Type property identifies.
        SiteMapNode siteNode = node.Item as SiteMapNode;
        Response.Write(whitespace + siteNode.Url + br);
        Response.Write(whitespace + siteNode.Description + br);
    }
    else if (node.Type == "SomeBusinessObject")
    {
        // If the IHierarchyData instance is a wrapper class on a business
        // object of some kind, you can retrieve the business object by using
        // the IHierarchyData.Item property.
        //          SomeBusinessObject busObj = node.Item as SomeBusinessObject;
    }

    if (node.HasChildren)
    {
        IEnumerator children = ((IHierarchicalEnumerable)node.GetChildren()).GetEnumerator();

        while (children.MoveNext())
        {
            // Print out SiteMapNode Titles recursively.
            IHierarchyData hierarchicalNode = node.GetChildren().GetHierarchyData(children.Current);
            PrintFullChildNodeInfo(hierarchicalNode);
        }
    }
}
' Print out the current data node, then iterate through its
' children and do the same.

Private Sub PrintFullChildNodeInfo(ByVal node As IHierarchyData)
    Dim whitespace As String = "&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"
    Dim br As String = "<BR>"

    Response.Write(Convert.ToString(node) & br)
    Response.Write(whitespace & node.Path & br)

    ' Check for specific types and perform extended functions.
    If node.Type = "SiteMapNode" Then
        ' Because SiteMapNode implements the IHierarchyData interface,
        ' the IHierarchyData object can be cast directly as a SiteMapNode,
        ' rather than accessing the Item property for the object that
        ' the Type property identifies.
        Dim siteNode As SiteMapNode = CType(node.Item, SiteMapNode)
        Response.Write(whitespace & siteNode.Url & br)
        Response.Write(whitespace & siteNode.Description & br)

    ElseIf node.Type = "SomeBusinessObject Then" Then
        ' If the IHierarchyData instance is a wrapper class on a business
        ' object of some kind, you can retrieve the business object by using
        ' the IHierarchyData.Item property.
        '          SomeBusinessObject busObj = node.Item as SomeBusinessObject;
    End If

    If node.HasChildren Then
        Dim children As IEnumerator = CType(node.GetChildren().GetEnumerator(), IHierarchicalEnumerable)
        While children.MoveNext()
            ' Print out SiteMapNode Titles recursively.
            Dim hierarchicalNode As IHierarchyData = node.GetChildren().GetHierarchyData(children.Current)

        End While
    End If
End Sub

설명

합니다 Type 속성을 반환 하지 않습니다는 System.Type 나타나는 개체의는 IHierarchyData 개체입니다.The Type property does not return the System.Type of the object represented in an IHierarchyData object. 계층에서 다른 바인딩 가능한 속성을 가진 항목을 구분 하기 위해 데이터 바인딩된 컨트롤에서 사용 하는 이름을 반환 합니다.It returns a name used by data-bound controls to differentiate between items in a hierarchy that have different bindable properties.
