Delete node with C# in XML

Question

I'm Trying to Delete a node from XML with C#, but for some reason I can't.

What I doing wrong?

The code runs well, respond with true, but the XML don't change and the node is not eliminated.

This is my code to Delete:

internal static bool DeleteCamera(string name)
    {
        XmlDocument xml = new XmlDocument();
        xml.Load("xmlpath.xml");
        XmlNode toDelete = xml.SelectSingleNode("//Camera[@Name='" + name + "']");
        if (toDelete == null)
        {
            return false;
        }
        else
        {
            toDelete.ParentNode.RemoveChild(toDelete);
            xml.Save("xmlpath.xml");
            return true;
        }
    }

This is my XML result with WCF service:

<Cameras>
   <Camera Name="Camara1" Url="Camara1" Width="600" Height="800" />
   <Camera Name="Camara2" Url="Camara2" Width="600" Height="800" />
</Cameras>

Answer 1

Thank you guys, the problem was the containing apostrophe (?) before and after name string.

XmlNode toDelete = xml.SelectSingleNode("//Camera[@Name='" +name+ "']");

But I don't know why I need to restart the service to see the changes if I have a Method to load the xml file.

Use xml linq. The name in xml is "Camara1" not "Camera1".

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Xml.Linq;

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XDocument doc = XDocument.Load(FILENAME);
            string removeName = "Camara1";
            XElement camera = doc.Descendants().Where(x => (x.Name.LocalName == "Camera") && ((string)x.Attribute("Name") == removeName)).FirstOrDefault();

            camera.Remove();

        }
    }
}
