VB.Net CALL rest API使用request.AddBody

如何解决VB.Net CALL rest API使用request.AddBody

如何使用request.AddBody方法在 VB.Net中将主体参数添加到其余API请求？

下面是我在C＃中的代码，但我想在 VB.Net

 RestClient client = new RestClient("URL of API service");
 RestRequest request = new RestRequest("/MethodName",Method.POST);

request.AddHeader("Accept","application/json");
request.RequestFormat = DataFormat.Json;
request.AddBody(new SampleClass 
                {
                    Property1 = Guid.NewGuid().ToString(),Property2 = "",Property3 = 123
                });

if (response.StatusCode == System.Net.HttpStatusCode.OK)
{
//Deserialize JSON content string to object
SampleResponse responSEObj = JsonConvert.DeserializeObject<SampleResponse>(response.Content);

if (responSEObj == null)
{
 throw new Exception("Error msg");
}

if (responSEObj.ResultList != null)
 {
 rVal = responSEObj.ResultList.ToList();
                      
}
else
{
throw new exception("Error in API");
}
}

如何在VB中添加以上代码，尤其是类中的request.AddBody内容？
