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

The HTTP PUT method is used to completely replace a resource on the API server. We can use the HttpClient to send a PUT request to an API server using the SendJsonAsync () method.

CSHTML

@page "/employee/edit"
@inject HttpClient Http

.. .. .. .. .. .. 
.. .. .. .. .. ..

@code {
    Employee emp = new Employee();
    protected async Task UpdateEmployee()
    {
        await Http.SendJsonAsync(HttpMethod.Put, "api/Employee/Edit", emp);
        UriHelper.NavigateTo("/employee");

    }
}

WEB API

[HttpPut]
[Route("api/Employee/Edit")]
public void Edit([FromBody]Employee employee)
{
    if (ModelState.IsValid)
        this.employee.UpdateEmployee(employee);
}
