我正在尝试执行以下API调用

RetrieveRecordChangeHistoryRequest

我正试着跟着 this steps ,但我无法复制代码,因为我遇到了一系列错误。

我已成功安装Dynamics 365 HelperCode,但开始管理我不了解的代码为什么不起作用。(我在C#方面没有经验)

using Microsoft.Crm.Sdk.Samples.HelperCode;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using System.Net.Http;
using System.Net.Http.Headers;

private HttpClient httpClient;


private void ConnectToCRM(String[] cmdargs)
{
    Configuration config = null;
    if (cmdargs.Length > 0)
        config = new FileConfiguration(cmdargs[0]);
    else
        config = new FileConfiguration(null);
    Authentication auth = new Authentication(config);
    httpClient = new HttpClient(auth.ClientHandler, true);
    httpClient.BaseAddress = new Uri(config.ServiceUrl + "api/data/v8.1/");
    httpClient.Timeout = new TimeSpan(0, 2, 0);
    httpClient.DefaultRequestHeaders.Add("OData-MaxVersion", "4.0");
    httpClient.DefaultRequestHeaders.Add("OData-Version", "4.0");
    httpClient.DefaultRequestHeaders.Accept.Add(
        new MediaTypeWithQualityHeaderValue("application/json"));
}



Program app = new Program();
try
{
    String[] arguments = Environment.GetCommandLineArgs();
app.ConnectToCRM(arguments);
}
catch (System.Exception ex)
{ ; }
finally
{
    if (app.httpClient != null)
    { app.httpClient.Dispose(); }
}


private static void DisplayException(Exception ex)
{
    Console.WriteLine("The application terminated with an error.");
    Console.WriteLine(ex.Message);
    while (ex.InnerException != null)
    {
        Console.WriteLine("\t* {0}", ex.InnerException.Message);
        ex = ex.InnerException;
    }
}
