在C＃Convert.ChangeType（jobj [p.Name] .ToString（），p.ParameterType）中

Question

Code for execute service dynamically in C# which has JSON object

var jobj = JObject.FromObject(JSON Object);
object instance= new RestServices();

var mi = instance.GetType().GetMethod(jobj["method"].ToString(), BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic);
var parameters = mi.GetParameters()
             .Select(p => Convert.ChangeType(jobj[p.Name].ToString(), p.ParameterType))
             .ToArray();

object retval = mi.Invoke(instance, parameters);

I have services which have following parameters

1.InfoEdit service
{
  "method": "InfoEdit",                   
  "storeId":"1",
  "personalInfo": {
                  "Gender":"test",
                  "FirstName": "test",
                  "CompanyName": "test",
                  "PhoneNumber":"1153646",
                  "NewsLetter":"1"
                  }       
};
2.Login service
{
  "method": "Login",
  "apiSecretKey": "y109m113e122",
  "userName": "test@test.com",
  "password": "test",
  "isGuestCustomerId": 1
}

For 1st( InfoEdit service) request parameters, I got an error "Invalid cast from 'System.String' to 'DataClass.InfoEditResponse'" , while for 2nd( Login service) request parameters my service called without any hassle.

If anyone have idea about it then please suggest.

Thank You in advance :)

All you need is to use the ToObject method of JObject

var parameters = mi.GetParameters()
                .Select(p => jobj[p.Name].ToObject(p.ParameterType))
                .ToArray();

object retval = mi.Invoke(instance, parameters);
