REST API get not accepting multiple parameters in C#

I am using .NET 4.5 framework to build a REST API. This API has a get method with multiple parameters, but when I call the API, then it shows the bad request second parameter is null. In reality, I am passing the value for second parameter. Below is the method implementation,

[HttpGet()]
[Route("api/Mycontroller/{useid:int}")]
public List<GetDetails> GET([FromUri()] int useid,  DateTime loginDate)
{
    // Some logic
}

Request through C# code:

HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost/abc/");
client.DefaultRequestHeaders.Clear();

client.DefaultRequestHeaders.Accept.Add(
            new MediaTypeWithQualityHeaderValue("application/json"));

HttpResponseMessage clientResponse = Task.Run(async () => { return await client.GetAsync("api/Mycontroller/" + userid+"?LoginDate=" +TodaysDateParameter); }).Result;

Here result is returning null value due to bad request.

I tried various possibilities of query string, but nothing worked. I tried to remove route fromuri(), fromBody() but that was also not helpful.

What am I doing wrong?

You need to also add your second parameter to the [Route] attribute on your method - like this:

[Route("api/Mycontroller/{useid:int}/{loginDate}")]
public List<GetDetails> GET([FromUri()] int useid,  DateTime loginDate)

Then you can call your API method like this:

string queryUrl = $"api/Mycontroller/{userid}/{TodaysDateParameter}";

HttpResponseMessage clientResponse = Task.Run(async () => { return await client.GetAsync(queryUrl).Result;
