在不改变CSV文件内容的情况下同步

Question

我正在尝试使用HttpClient与putasync发送文件到服务器。函数如下所示:

public async Task SendCsvFile(string path,string apiKey)
{
try
{
string clientKey = "";
LoggerService.Logger.CreateLog("Log");
LoggerService.Logger.Info("Start:SendCsvFile");
FileStream fileStream = null;
HttpClientHandler clientHandler = new HttpClientHandler();
clientHandler.ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => { return true; };
HttpClient httpClient = new HttpClient(clientHandler);
httpClient.DefaultRequestHeaders.Accept.Clear();   
httpClient.DefaultRequestHeaders.Add("x-api-key", clientKey);
string url = "https://test.csv";
var content = new MultipartFormDataContent();
var fileName = Path.GetFileName(path);
fileStream = File.OpenRead(path);
StreamContent streamContent = new StreamContent(fileStream);
content.Add(new StreamContent(fileStream), fileName, fileName);
var response = await httpClient.PutAsync(url, content);
if (response.IsSuccessStatusCode == true)
{
LoggerService.Logger.Info("File sent correctly.");
}
else
{
LoggerService.Logger.Error("Error during sending." + response.StatusCode + ";" + response.ReasonPhrase + ";");
}
fileStream.Close();
LoggerService.Logger.Info("End:SendCsvFile");
}
catch (Exception ex)
{
LoggerService.Logger.Error(ex.ToString());
//return 0;
}

//return 1;
}

文件发送良好，它的工作，但内容处置头被添加到文件的第一行，客户端不希望这样。这是我第一次用服务做任何事情，我读了很多，但我仍然不知道我可以改变什么来不改变csv文件的内容。

编辑。在我发送后，文件头被添加到内容中，所以文件看起来是这样的。客户端服务器截图

所有数据都很好，尽管客户机服务器处理数据的方式应该从列名开始。所以我的问题是我可以改变省略第一行,甚至是可能的。也许这是显而易见的，但我在这方面只是个新手。

更改为MultipartContent和清除header几乎可以工作，但让我在文件中仍然可以看到边界。最后，我改用RestSharp，并以这种方式添加内容，解决了这个问题。

public async Task SendCsvFile(string path, string apiKey)
{
try
{
string clientKey = "";
string url = "";
LoggerService.Logger.CreateLog("CreationAndDispatchStatesWithPrices");
LoggerService.Logger.Info("Start:SendCsvFile");
FileStream fileStream = null;
var fileName = Path.GetFileName(path);
fileStream = File.OpenRead(path);
var client = new RestClient(url);
//            client.Timeout = -1;
var request = new RestRequest();
request.AddHeader("x-api-key", clientKey);
request.AddHeader("Content-Type", "text/csv");
request.AddParameter("text/csv", File.ReadAllBytes(path), ParameterType.RequestBody);
RestResponse response = client.Put(request);
if (response.IsSuccessful == true)
{
LoggerService.Logger.Info("File sent correctly.");
}
else
{
LoggerService.Logger.Error("Error sending file." + response.StatusCode + ";" + response.ErrorMessage + ";");
}
fileStream.Close();
LoggerService.Logger.Info("End:SendCsvFile");
}
catch (Exception ex)
{
LoggerService.Logger.Error(ex.ToString());
//return 0;
}

//return 1;
}
