Örnekler

Aşağıdaki örnek iki XML ağacı oluşturur ve sonra bu yöntemi kullanarak bir sorgunun sonuçlarını bunlardan birine ekler.

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("NewElement", "Content")  
);  
xmlTree.Add(  
    from el in srcTree.Elements()  
    where (int)el >= 3  
    select el  
);  
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>  
            <NewElement>Content</NewElement>  
        </Root>  
xmlTree.Add( _  
    From el In srcTree.Elements _  
    Where CInt(el) >= 3 _  
    Select el)  
Console.WriteLine(xmlTree)  

Bu örnek aşağıdaki çıkışı oluşturur:

<Root>  
  <NewElement>Content</NewElement>  
  <Element3>3</Element3>  
  <Element4>4</Element4>  
  <Element5>5</Element5>  
</Root>
