Question

我尝试使用ASP 5.0 WebAPI在Customer控制器中进行分页。当我尝试这个例子时，我得到：

无法隐式转换类型Microsoft.AspNet.Mvc.HttpOkObjectResult 到API.Controllers.IHttpActionResult

我只需要返回一组客户，其中包含当前页面的编号，页面总数和结果。

public IHttpActionResult Get(int offset = 0, int limit = 50)
{
    // Get total number of records
    int total = _dbContext.Customers.Count();

    // Select the customers based on paging parameters
    var customers = _dbContext.Customers
        .OrderBy(c => c.Id)
        .Skip(offset)
        .Take(limit)
        .ToList();

    // Return the list of customers
    return Ok(new
    {
        Data = customers,
        Paging = new
        {
            Total = total,
            Limit = limit,
            Offset = offset,
            Returned = customers.Count
        }
    });
}

您需要将IHttpActionResult更改为IActionResult

Controller.Ok()返回HttpOkObjectResult ...

public class HttpOkObjectResult : ObjectResult, IActionResult {...}

...虽然您的方法签名定义了IHttpActionResult，它来自之前的版本

WebAPI One Asp.Net中的分页（ASP5 / vNext）
