XNodeDocumentOrderComparer 构造函数

定义

初始化 XNodeDocumentOrderComparer 类的新实例。Initializes a new instance of the XNodeDocumentOrderComparer class.

public:
 XNodeDocumentOrderComparer();
public XNodeDocumentOrderComparer ();
Public Sub New ()

示例

下面的示例使用此类来比较两个节点的文档顺序。The following example uses of this class to compare the document order for two nodes.

XElement xmlTree = new XElement("Root",  
    new XText("Text content."),  
    new XElement("Child1", "child1 content"),  
    new XElement("Child2", "child2 content"),  
    new XElement("Child3", "child3 content"),  
    new XText("More text content."),  
    new XElement("Child4", "child4 content"),  
    new XElement("Child5", "child5 content")  
);  
XElement child3 = xmlTree.Element("Child3");  
XElement child5 = xmlTree.Element("Child5");  
XNodeDocumentOrderComparer documentOrderComparer = new XNodeDocumentOrderComparer();  
int val = documentOrderComparer.Compare(child3, child5);  
if (val == 0)  
    Console.WriteLine("Child3 is same as Child5");  
else if (val < 0)  
    Console.WriteLine("Child3 is before Child5");  
else  
    Console.WriteLine("Child3 is after Child5");  

该示例产生下面的输出:This example produces the following output:

Child3 is before Child5  

注解

建议使用方法,而不是直接使用此类 InDocumentOrderWe recommend that instead of using this class directly, you use the InDocumentOrder method. 此类由该方法在内部使用。This class is used internally by that method.
