Custom class is not able to be used with generic type T

Hello everyone I am just programming and run into a problem. I wrote a custom class:

namespace DMIS_API.Models
{
    public class ServiceResponse<T>
    {
        public T? Data { get; set; }
        public bool Success { get; set; } = true;
        public string Message { get; set; } = string.Empty;
        public int ErrorCode { get; set; } = 0;
    }
}

namespace DMIS_API.Models
{
    public class ServiceResponse<T>
    {
        public T? Data { get; set; }
        public bool Success { get; set; } = true;
        public string Message { get; set; } = string.Empty;
        public int ErrorCode { get; set; } = 0;
    }
}

However when I want to call it as a method parameter with generic type T it does not work: private void DoSomeThing(ref ServiceResponse<T> serviceResponse){...} it does not work. Can someone please help me?

$details, "does not work" isn't specific

When you ask a question, make sure you include as much detail as possible. Such as code, the issue you are facing, and what you expect the result to be. Upload code here https://paste.mod.gg/ (see $code for more information on how to paste your code)

provide an example of the code you're trying to write and share the errors you're getting

Are you literally typing T in the calling method as the type parameter?

I want to use the method to be able to run with any type for the rapper ServiceRespone. A Example for ServiceRespone would be ServiceRespone<List<GetProductDto>> or ServiceRespone<GetProduct>.

then the method has to be generic as well like DoSomeThing<T>(ref ServiceResponse<T> serviceResponse){...}

YoloJoeYoloOP•16mo ago

It is So after the name of the method I have to wright <T>?

Jimmacle•16mo ago

yes, that's how you define a generic method

YoloJoeYoloOP•16mo ago

I tested it your right

Jimmacle•16mo ago

if you don't do that it's not generic and T has no meaning in that context
