我可以在不循环的情况下从XML文档声明和填充数组吗？

Question

I 'd like to fill a new string array with elements from an XML document.

In VBA I've managed this logic with a collection:

For Each x In xmlDoc.SelectNodes("//a")
    MyCollection.add (x.Attributes.getNamedItem("href").Text)
Next x

But what I really want to do is get the same collection in to an array in C#, something like:

string[] MyArray = new string[]
    {
        xmlDoc.SelectNodes("//a").Attributes.getNamedItem("href").Text
    };

Is this possible? Or some similar way to do it without looping and adding individually to the array?

Answer 1

This will do

string[] MyArray = XDocument.Parse(xml).XPathSelectElements("//a").Select(e => e.Attributes("href").FirstOrDefault().Value).ToArray()`

Edit: Requires Using System.Xml.XPath and Using System.XML.Linq to work

Answer 2

You can use LINQ to achieve something like that:

string[] MyArray = xmlDoc
    .SelectNodes("//a")
    .Cast<XmlNode>()
    .Select(e => e.Attributes.GetNamedItem("href").InnerText)
    .ToArray();

Don't forget to import Linq ( using System.Linq; )
