Json Value doesn't assign to the List [HttpPost]

Since am new to web api, i am finding some difficulty to post json List to Web API.

Json
[  
   {  
      "ItemId":20,
      "RegId":"VISIT0001778",
      "BLoadDetailId":"8/31/2018 12:28:10 PM",
      "OrderReferenceNo":null,
      "StartTime":"0001-01-01T00:00:00",
      "InvalidItemMsg":"",
      "InvalidItemstatus":false,
      "BLoadingBay":"Chute 009",
      "BLoadingBayCode":null,
      "BLoadingBayID":7,
      "RFID":7123,
      "GangId":2,
      "BOrderTransfer":false,
      "BLoadedBags":0.0,
      "BRemainingBags":0.0,
      "BConversionValue":null,
      "WHid":2
   }
]

class :

 public class clsStartTimeUpdate
 {
     public int ItemId { get; set; }
     public string RegId { get; set; }
     public string BLoadDetailId { get; set; }
     public string OrderReferenceNo{ get; set; }
     public DateTime StartTime { get; set; }
     public string InvalidItemMsg { get; set; }
     public bool InvalidItemstatus { get; set; }
     public string BLoadingBay { get; set; }
     public string BLoadingBayCode { get; set; }
     public int? BLoadingBayID { get; set; }
     public long? RFID { get; set; }
     public int? GangId { get; set; }
     public bool BOrderTransfer { get; set; }
     public decimal BLoadedBags { get; set; }
     public decimal BRemainingBags { get; set; }
     public string BConversionValue { get; set; }
     public int? WHid { get; set; }
 }

Json request 

http://localhost:49290/api/config/Post?StartTimeDetails=[enter image description here][1][{%22ItemId%22:20,%22RegId%22:%22VISIT0001778%22,%22BLoadDetailId%22:%228/31/2018%2012:28:10%20PM%22,%22OrderReferenceNo%22:null,%22StartTime%22:%222001-01-01T00:00:00%22,%22InvalidItemMsg%22:%22%22,%22InvalidItemstatus%22:false,%22BLoadingBay%22:%22Chute%20009%22,%22BLoadingBayCode%22:null,%22BLoadingBayID%22:7,%22RFID%22:7123,%22GangId%22:2,%22BOrderTransfer%22:false,%22BLoadedBags%22:0.0,%22BRemainingBags%22:0.0,%22BConversionValue%22:null,%22WHid%22:2}]

Method WebAPI

[HttpPost]
public HttpResponseMessage Post([FromUri]List<clsStartTimeUpdate> StartTimeDetails)
{          
    return base.BuildSuccessResult(HttpStatusCode.OK, StartTimeDetails);
}

result:

[{"ItemId":0,"RegId":null,"BLoadDetailId":null,"OrderReferenceNo":null,"StartTime":"0001-01-01T00:00:00","InvalidItemMsg":null,"InvalidItemstatus":false,"BLoadingBay":null,"BLoadingBayCode":null,"BLoadingBayID":null,"RFID":null,"GangId":null,"BOrderTransfer":false,"BLoadedBags":0.0,"BRemainingBags":0.0,"BConversionValue":null,"WHid":null}]

return result doesnot assign the values as in the Json. May be this is a simple situation , but i really appreciate the help.

For complex types Always use [FromBody] in the argument.

[HttpPost]
public HttpResponseMessage Post([FromBody]List<clsStartTimeUpdate> StartTimeDetails)
{          
    return base.BuildSuccessResult(HttpStatusCode.OK, StartTimeDetails);

}

And then specify your query object in Body.

Note: To specify the value in the body, You will need an API client like Postman or Swagger. https://www.getpostman.com/

In Postman,

Select Post method and specify the URL, Then go to "Body" tab and select raw. Specify JSON as type. In the body, paste your data.

   { [
     {
        "ItemId":20,
        ..........
     }
    ]}

The Other answer by @ershoaib is the real fix for the problem that OP is facing. However, I am leaving this answer as it is the standard which should be followed.

It seems that you want to convey your json with HttpGet request instead of HttpPost then you can follow below,

1) Send Json with HttpGet

Method: Get

Url: http://localhost:49290/api/config/MyGet?StartTimeDetails=[{%22ItemId%22:20,%22RegId%22:%22VISIT0001778%22,%22BLoadDetailId%22:%228/31/2018%2012:28:10%20PM%22,%22OrderReferenceNo%22:null,%22StartTime%22:%220001-01-01T00:00:00%22,%22InvalidItemMsg%22:%22%22,%22InvalidItemstatus%22:false,%22BLoadingBay%22:%22Chute%20009%22,%22BLoadingBayCode%22:null,%22BLoadingBayID%22:7,%22RFID%22:7123,%22GangId%22:2,%22BOrderTransfer%22:false,%22BLoadedBags%22:0.0,%22BRemainingBags%22:0.0,%22BConversionValue%22:null,%22WHid%22:2}]

Web Api Method: 

[HttpGet]
public HttpResponseMessage MyGet(string StartTimeDetails)
{
    List<clsStartTimeUpdate> clsStartTimeUpdates = JsonConvert.DeserializeObject<List<clsStartTimeUpdate>>(StartTimeDetails);
    return base.BuildSuccessResult(HttpStatusCode.OK, StartTimeDetails);
}

Note: Its bad practice to send huge json in query string, so for use HttpPost instead

2) Send Json with HttpPost

Method: Post

Url: http://localhost:49290/api/config/MyPost

Data: 

[  
   {  
      "ItemId":20,
      "RegId":"VISIT0001778",
      "BLoadDetailId":"8/31/2018 12:28:10 PM",
      "OrderReferenceNo":null,
      "StartTime":"0001-01-01T00:00:00",
      "InvalidItemMsg":"",
      "InvalidItemstatus":false,
      "BLoadingBay":"Chute 009",
      "BLoadingBayCode":null,
      "BLoadingBayID":7,
      "RFID":7123,
      "GangId":2,
      "BOrderTransfer":false,
      "BLoadedBags":0.0,
      "BRemainingBags":0.0,
      "BConversionValue":null,
      "WHid":2
   }
]

Web Api Method: 

[HttpPost]
public HttpResponseMessage MyPost([FromBody]List<clsStartTimeUpdate> StartTimeDetails)
{
    return base.BuildSuccessResult(HttpStatusCode.OK, StartTimeDetails);
}

Since you are using post you should expect the data in the controller method to come from body. See related issue here
