RestClient POST到API在Release Build中不起作用

Question

我有一个奇怪的问题，我不确定如何修复。目标是使用RestClient发布到API。这在Visual Studio中的调试模式下工作正常。但是，当我为Release构建项目并直接打开.exe时。 POST返回状态代码为0.

以下是我使用的一些代码片段。这还有点新意。谢谢你的帮助。

var url = "https://testurl.com";


//ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;

// create a new RestSharp client
var client = new RestClient(url);

try
{
    var request = new RestRequest(Method.POST)
    {
        RequestFormat = RestSharp.DataFormat.Json
    };

    request.AddParameter("application/json; charset=utf-8", json, ParameterType.RequestBody);

    MessageBox.Show(url);
    var response = client.Execute(request);

    if (response.StatusCode == System.Net.HttpStatusCode.OK || response.StatusCode == System.Net.HttpStatusCode.Created)
    {
        Console.WriteLine(JToken.Parse(response.Content));
        ProcessResponse(response.Content);
    }
    else
    {
        MessageBox.Show("Request returned a status other than OK" + Environment.NewLine + "StatusCode: " + response.StatusCode.ToString() + Environment.NewLine + response.Content + Environment.NewLine + "The certificate used was " + cert.ToString(), "Error");
    }
}
catch (Exception ex)
{
    MessageBox.Show(ex.Message, "There was a problem.");
}
