How do you send an HTTP DELETE request using HttpClient in Blazor?

An HTTP Delete request can be sent to delete a resource from the API server using the DeleteAsync () method provided by the HttpClient class.

Razor

@page "/employee/delete"
@inject HttpClient Http
@inject NavigationManager Navigate
.. .. .. .. .. .. 
.. .. .. .. .. ..

@code {
    Employee emp = new Employee();
    protected async Task Delete()
    {
        await Http.DeleteAsync("api/Employee/Delete/" + Convert.ToInt32(empID));
        Navigate.NavigateTo("/employee");
    }
}

Web API

[HttpDelete]
[Route("api/Employee/Delete/{id}")]
public void Delete(int id)	
{
    employee.DeleteEmployee(id);
}
