Web method call returns bad request

Please consider these two Web API methods:

[HttpPost]
[Route(getdata1)]
public IActionResult Getdata1()
{
    return Ok("Hello")
}

[HttpPost]
[Route(getdata2)]
public IActionResult Getdata2([FromBody] string name)
{
    return Ok("Hello" + name)
}

When I call first method with the code shown here, it is ok and I get Hello message:

String url: "https://localhost:1234/api/getdata1";
var client = HttpClient();
var Response = client.PostAsync(url, null).Result;

if (Response.IsSuccessStatusCode)
{
    Console.Write(Response.Content.ReadAsStringAsync().Result);
}
else
{
    Console.Write(Response.StatusCode);
}

But when I call the second method with the code shown, I get BadRequest error:

String url: "https://localhost:1234/api/getdata2";

var tmp = new { name = "Test" }

var json = JsonSerializer.Serialize(tmp);

var Parameter = new StringContent(json, Encoding.UTF8, "application/json")

var client = HttpClient();
var Response = client.PostAsync(url, Parameter).Result;

if (Response.IsSuccessStatusCode)
{
    Console.Write(Response.Content.ReadAsStringAsync().Result);
}
else
{
    Console.Write(Response.StatusCode);
}

Please help me.

You are posting the JSON object to the "Getdata2" API. The API action's argument should be an object/class type instead of string.

[HttpPost]
[Route(getdata2)]
public IActionResult Getdata2([FromBody] GetDataInput model)
{
    return Ok("Hello" + model.Name);
}

public class GetDataInput
{
    public string Name { get; set; }
}
