使用ExecuteReader我能够返回一个DataReader,但out参数返回0.

使用ExecuteNonQuery我能够检索out参数(具有正确的值),但ExecuteNonQuery不返回a DataReader.

这是给出上下文的过程:

SQL查询:

CREATE PROCEDURE [dbo].[SelectDays]
    @dateStart datetime,
    @dateEnd datetime,
    @recordCount bigint out
AS
BEGIN
    select @recordCount = count(*)
    from dbo.[Days]
    where [Date]>=@dateStart and [Date]<=@dateEnd;

    select [ID],[Name]
    from dbo.[Days]
    where [Date]>=@dateStart and [Date]<=@dateEnd;
END

有没有一种方法,我可以返回一个DataReader还有out参数,或者我应该为每个两个独立的程序？

C#代码:

     Int32 returnValue = 0;

     Parameters parameters = new Parameters();
     parameters.Add(new SqlParameter("@dateStart", dateStart != null ? (object)dateStart : DBNull.Value));
     parameters.Add(new SqlParameter("@dateEnd", dateEnd != null ? (object)dateEnd …

我有一个示例控制器:

[RoutePrefix("api/Example")]
public class ExampleController : ApiController
{
    [Route("Foo")]
    [HttpGet]
    public string Foo([FromUri] string startDate)
    {
        return "This is working";
    }

    [Route("Bar")]
    [HttpPost]
    public string Bar([FromBody] DateTime startDate)
    {
        return "This is not working";
    }
}

当我发出GET请求时:http://localhost:53456/api/Example/Foo?startDate=2016-01-01它有效.

当我POST到http://localhost:53456/api/Example/Bar我收到HTTP/1.1 400 Bad Request错误.

这是我的POST数据:

{
"startDate":"2016-01-01T00:00:00.0000000-00:00"
}

我究竟做错了什么？

我正在尝试在 .NET 4.5 控制台应用程序上运行以下代码：

var app = WebApp.Start<Startup>("http://127.0.0.1:9000/");

这适用于我同事的机器，但不适用于我的。

异常消息为“ Exception has been thrown by the target of an invocation.”，内部异常为“ The network location cannot be reached. For information about network troubleshooting, see Windows Help”。

我试过关闭防火墙，重置主机文件，没有运行反病毒，刷新我的 DNS 并清理/重建我的解决方案。
