O exemplo a seguir cria duas árvores XML e, em seguida, usa esse método para adicionar um XElement objeto a um deles.The following example creates two XML trees, and then uses this method to add an XElement object to one of them. Ele também adiciona os resultados de uma LINQLINQ consulta à árvore XML.It also adds the results of a LINQLINQ query to the XML tree.

XElement srcTree = new XElement("Root",  
    new XElement("Element1", 1),  
    new XElement("Element2", 2),  
    new XElement("Element3", 3),  
    new XElement("Element4", 4),  
    new XElement("Element5", 5)  
);  
XElement xmlTree = new XElement("Root",  
    new XElement("Child1", 1),  
    new XElement("Child2", 2),  
    new XElement("Child3", 3),  
    new XElement("Child4", 4),  
    new XElement("Child5", 5)  
);  
xmlTree.Add(new XElement("NewChild", "new content"));  
xmlTree.Add(  
    from el in srcTree.Elements()  
    where (int)el > 3  
    select el  
);  
// Even though Child9 does not exist in srcTree, the following statement will not  
// throw an exception, and nothing will be added to xmlTree.  
xmlTree.Add(srcTree.Element("Child9"));  
Console.WriteLine(xmlTree);  

Dim srcTree As XElement = _   
        <Root>  
            <Element1>1</Element1>  
            <Element2>2</Element2>  
            <Element3>3</Element3>  
            <Element4>4</Element4>  
            <Element5>5</Element5>  
        </Root>  

Dim xmlTree As XElement = _   
        <Root>  
            <Child1>1</Child1>  
            <Child2>2</Child2>  
            <Child3>3</Child3>  
            <Child4>4</Child4>  
            <Child5>5</Child5>  
        </Root>  

xmlTree.Add(New XElement("NewChild", "new content"))  
xmlTree.Add( _  
    From el In srcTree.Elements() _  
    Where CInt(el) > 3 _  
    Select el _  
)  
' Even though Child9 does not exist in srcTree, the following statement will not  
' throw an exception, and nothing will be added to xmlTree.  
xmlTree.Add(srcTree.<Child9>)  
Console.WriteLine(xmlTree)  

Esse exemplo gera a saída a seguir:This example produces the following output:

<Root>  
  <Child1>1</Child1>  
  <Child2>2</Child2>  
  <Child3>3</Child3>  
  <Child4>4</Child4>  
  <Child5>5</Child5>  
  <NewChild>new content</NewChild>  
  <Element4>4</Element4>  
  <Element5>5</Element5>  
</Root>
