我需要幫助將以下 Python 代碼轉換為 c# .net。此代碼將文本文件發布/上傳到網絡服務器。Python 腳本已經過測試并且可以正常工作。我已經嘗試了一些使用 HTTPClient 和 WebRequest 的解決方案，但沒有成功。任何指導將不勝感激。# request a sessionclient = requests.session()# Establish the URLnewurl = 'https://localhost/filedist/upload/'source_file = 'data/test.txt'headers = {'Authorization': 'Token MYTOKEN'}# Populate the values with our environment and target pathvalues = dict(environment='dev', path='Business/Tools')files = dict(file=open(source_file, 'rb'))r = client.post(newurl, files=files, data=values, headers=headers)這是我的最新嘗試，目前正在收到“禁止”錯誤。    public static async Task<string> UploadFile(string path, string fileName)    {        var client = new HttpClient();        string NewURL = "https://localhost/filedist/upload/";        string SourceFile = path;        var content = new MultipartFormDataContent();        client.DefaultRequestHeaders.Add("Authorization", "Token MYTOKEN");        Stream fs = System.IO.File.Open(path, FileMode.Open, FileAccess.Read, FileShare.None);        content.Add(CreateFileContent(fs, fileName, "text/plain"));        var parameters = new Dictionary<string, string> { { "environment", "dev" }, { "path", "Business/Tools" } };        content.Add(new FormUrlEncodedContent(parameters));        var response = await client.PostAsync(NewURL, content);        response.EnsureSuccessStatusCode();        if (response.IsSuccessStatusCode)        {            string responseString = response.Content.ReadAsStringAsync().Result;            return "true";        }        else        {            return "false";        }    }    private static StreamContent CreateFileContent(Stream stream, string fileName, string contentType)    {        try        {            var fileContent = new StreamContent(stream);            fileContent.Headers.ContentDisposition = new System.Net.Http.Headers.ContentDispositionHeaderValue("form-data")            {                Name = "UploadedFile",                FileName = "\"" + fileName + "\""            };
