MVC WebApi Get passing an object in C#

Question

I need to get a from and to date to my mvc webapi for retrieving items between those dates. Here is my favorite thing I have tried that has not worked (I have tried several things). I have an object that is shared between the projects: ``` public class SchedulerDateSpan { public DateTime StartDate { get; set; } public DateTime EndDate { get; set; } } ``` Here is my controller class for get: ``` public IEnumerable GetAppointments(SchedulerDateSpan dates) { IEnumerable appointments = db.Appointments.Where( a => (a.StartDate <= dates.StartDate && a.EndDate >= dates.StartDate) || (a.StartDate <= dates.EndDate && a.EndDate >= dates.EndDate) || (a.StartDate > dates.StartDate && a.EndDate < dates.EndDate)).AsEnumerable(); return appointments; } ``` Here is my call from the client where dates is of type SchedulerDateSpan: ``` var client = new HttpClient { BaseAddress = new Uri(Properties.Settings.Default.SchedulerWebApi) }; client.DefaultRequestHeaders.Accept.Add(new…

Accepted Answer

By default, complex type (such as your SchedulerDateSpan) are expected to be passed in the request body. You'll have to change mark the action parameter to be [FromUri] if you want the value to be passed from the URI:

```
public IEnumerable<Appointment> GetAppointments([FromUri]SchedulerDateSpan dates)
{...}
```

You can then pass the 'dates' from the query string in the Uri, like this:

```
HttpResponseMessage resp = client.GetAsync(
  String.Format("api/Appointments?dates.StartDate={0}&dates.EndDate={1}", 
    dates.StartDate.ToString(),
    dates.EndDate.ToString())).Result;
```
