Upload attachment using REST API from C#.NET

Question

Hi, We are creating a tool to migrate Versionone data to JIRA. So for this I am consuming REST APIs mentioned in "https://developer.atlassian.com/cloud/jira/platform/rest/v3/#api-api-3-issue-issueIdOrKey-remotelink-linkId-put". I am struggling to upload an attachment to an issue. All the time I am getting Statuscode as "200" but there is no attachment to the issue in JIRA. Here in below is my code, please suggest me what I am doing wrong here. Snippet SendFileToServer("XYZ-315"); Snippet private void SendFileToServer(string IssueKey) { FileInfo fi = new FileInfo(@C:\VersionOneAttachments\some.png); ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12; byte[] fileContents = File.ReadAllBytes(fi.FullName); //https://your-domain.atlassian.net/rest/api/2/issue/XYZ-315/attachments string urlPath = ConfigurationSettings.AppSettings.Get("JIRAURLForCreateIssue").ToString(); Uri webService = new Uri(string.Format("{0}/{1}/attachments", urlPath, IssueKey)); HttpRequestMessage requestMessage = new HttpRequestMessage(HttpMethod.Post, webService); requestMessage.Headers.ExpectContinue = false; MultipartFormDataContent multiPartContent = new MultipartFormDataContent("----MyGreatBoundary"); ByteArrayContent byteArrayContent = new ByteArrayContent(fileContents); byteArrayContent.Headers.Add("Content-Type", "image/png"); byteArrayContent.Headers.Add("X-Atlassian-Token", "no-check"); multiPartContent.Add(byteArrayContent, "this is the name of the content", fi.Name); requestMessage.Content = multiPartContent; HttpClient httpClient = new HttpClient(); httpClient.DefaultRequestHeaders.Add("Authorization", ConfigurationSettings.AppSettings.Get("JiraAuthorizationKey").ToString()); httpClient.DefaultRequestHeaders.Add("X-Atlassian-Token", "no-check"); try { Task httpRequest = httpClient.SendAsync(requestMessage, HttpCompletionOption.ResponseContentRead, CancellationToken.None); HttpResponseMessage httpResponse = httpRequest.Result; HttpStatusCode statusCode = httpResponse.StatusCode; HttpContent responseContent = httpResponse.Content; if (responseContent != null) { Task stringContentsTask = responseContent.ReadAsStringAsync(); String stringContents = stringContentsTask.Result; } } catch (Exception ex) { Console.WriteLine(ex.Message); } } Any idea will be appreciated. Thanks in advance Basanta Padhi
