That is a JSON within XML, as far as I can understand.

Please follow below process:

Step1: Add service reference to Windows App.

Step2: Add reference System.Web.Extensions;

Step3: Add namespace using System.Web.Script.Serialization;

Step4: Add below code:

C#

WebService1SoapClient cc = new WebService1SoapClient();
            string test = cc.validatelogin();
            
customer[] deserialized = new JavaScriptSerializer().Deserialize<customer[]>(test);

foreach (customer customerRec in deserialized)
{
    int id = customerRec.id;
    string name = customerRec.name;
    int uid = customerRec.uid;
}

Note: Make sure that customer class is available in Windows project also because it is required when we do deserializeation.
