Generic Task<object> method

问题

I have class to consuming my REST service.

Method for this will look like this:

public async Task<object> Get(string controller)
    {
        object data;
        HttpResponseMessage response = await this.HttpClient.GetAsync(UrlService.BuildEndpoint(controller));

        if (response.IsSuccessStatusCode)
        {
            data = await response.Content.ReadAsAsync<object>();
            return data;
        }
        else
        {
            throw new Exception(); //todo
        }
    }

in this case, object can be like my own class (Project, User etc) with propertys.

My question is, how to make Task<object> methods to be generic, that will take kind of objects that i want to (and return it)?

EDIT

When i do something like:

public async Task<TObject> Get<TObject>(string controller)
    {
        TObject data;
        HttpResponseMessage response = await this.HttpClient.GetAsync(UrlService.BuildEndpoint(controller));

        if (response.IsSuccessStatusCode)
        {
            data = await response.Content.ReadAsAsync<object>();
            return data;
        }
        else
        {
            throw new Exception(); //todo
        }
    }

i get an error on await repsonse.Contet...:

Cannot implicity convert object to TObject...

回答1:

You can use generic types:

public async Task<TObject> Get<TObject>(string controller)
    {
        TObject data;
        HttpResponseMessage response = await this.HttpClient.GetAsync(UrlService.BuildEndpoint(controller));

        if (response.IsSuccessStatusCode)
        {
            data = await response.Content.ReadAsAsync<TObject>();
            return data;
        }
        else
        {
            throw new Exception(); //todo
        }
    }

The following code would work:

public async Task<TObject> Get<TObject>(string controller)
{
    HttpResponseMessage response = await this.HttpClient.GetAsync(UrlService.BuildEndpoint(controller));

    if (response.IsSuccessStatusCode)
    {
        return await response.Content.ReadAsAsync<TObject>();
    }
    else
    {
        throw new Exception(); //todo
    }
}

Instead of "object" use a "T" type placeholder.

Try this:

  public async Task<T> Get (string controller)
  {
     T data;
     HttpResponseMessage response = await this.HttpClient.GetAsync (UrlService.BuildEndpoint (controller));

     if (response.IsSuccessStatusCode)
     {
        data = await response.Content.ReadAsAsync<T> ();
        return data;
     }
     else
     {
        throw new Exception (); //todo
     }
  }
