c#

这是我的代码。我无法返回Task<OkObjectResult>。我不想将返回类型转换为更具体的类型，例如Task<OkObjectResult>它会阻止我返回其他类型的结果，例如Task<BadRequestObjectResult>我无法更改方法的签名。这是 MediatR 的IRequestHandler

我该怎么做才能让它发挥作用？

public class Handler : IRequestHandler<Request, ActionResult>
{
    public Task<ActionResult> Handle(Request request, CancellationToken cancellationToken)
    {
        Task.FromResult(new OkObjectResult(new Response { IsHealthy = true }));
    }
}

回答

return Task.FromResult<ActionResult>(new OkObjectResult(new Response { IsHealthy = true }));
