XML Mapping is not workiing - C#

You can use Edit > Paste Special > Paste XML as Classes in the edit menu if you are using VS. Assuming your XML structure is correct this will give you:

Of course, such a method requires some work on properties, at least you can see the nesting of classes here. Then your deserialization will look like this:

XmlSerializer serializer = new XmlSerializer(typeof(Remote));
Remote res = new Remote();
using StreamReader reader = new StreamReader(fileLocation);
res = serializer.Deserialize(reader) as Remote;

It's about your model hierarchy. If you don't design your model correctly, you will encounter problems during deserialization.

Please take a look at the revised model structure below.
