        int workItemId = 123; // 替换为你的工作项ID
        string personalAccessToken = "YourPersonalAccessToken"; // 替换为你的个人访问令牌

        string url = $"https://dev.azure.com/{organization}/{project}/_apis/wit/workitems/{workItemId}/comments?api-version=6.0";

        string requestBody = @"

                                 .Replace("[DisplayName]", "DisplayName");

        using (HttpClient client = new HttpClient())

            var content = new StringContent(requestBody, Encoding.UTF8, "application/json");

            HttpResponseMessage response = client.PostAsync(url, content).Result;

            if (response.IsSuccessStatusCode)
