# 添加数据示例
本章节对添加数据AK/SK方式使用SDK进行示例说明。
添加数据示例代码只需将AK/SK信息替换为实际AK/SK，代码中可以使用AddDataParam类中的ImageUrl、Keywords、CustomNumTags、CustomTags、Desc、ItemId、Force参数配置服务输入参数；配置完成后运行即可。
1. 添加数据调用示例代码如下：
   ```
   using System;
   using System.Collections.Generic;
   using HuaweiCloud.SDK.Core;
   using HuaweiCloud.SDK.Core.Auth;
   using HuaweiCloud.SDK.ImageSearch;
   using HuaweiCloud.SDK.ImageSearch.V2;
   using HuaweiCloud.SDK.ImageSearch.V2.Model;
   namespace RunAddDataSolution
   {
       class Program
       {
           static void Main(string[] args)
           {
           //认证用的ak和sk硬编码到代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全
          //本示例以ak和sk保存在环境变量中来实现身份验证为例，运行本示例前请先在本地环境中设置环境变量HUAWEICLOUD_SDK_AK和HUAWEICLOUD_SDK_SK  
           string accessKey= Environment.GetEnvironmentVariable("HUAWEICLOUD_SDK_AK", EnvironmentVariableTarget.Machine);
           string secretKey= Environment.GetEnvironmentVariable("HUAWEICLOUD_SDK_SK", EnvironmentVariableTarget.Machine);
               const string iamEndpoint = "https://iam.cn-north-4.myhuaweicloud.com";
               const string endpoint = "https://mms.cn-north-4.myhuaweicloud.com";
               const string projectId = "project_id";
               var config = HttpConfig.GetDefaultConfig();
               config.IgnoreSslVerification = true;
               var auth = new BasicCredentials(ak, sk, projectId).WithIamEndpoint(iamEndpoint);
   
   // 初始化客户端
               var client = ImageSearchClient.NewBuilder()
                       .WithCredential(auth)
                       .WithRegion(new Region("cn-north-4", endpoint))
                       .WithHttpConfig(config)
                       .Build();
               var req = new RunAddDataRequest
               {
                   ServiceName = "service_name"
               };
               Dictionary<string, double?> listCustomNumTagsbody = new Dictionary<string, double?>();
               listCustomNumTagsbody.Add("key", 1);
               Dictionary<string, string> listCustomTagsbody = new Dictionary<string, string>();
               listCustomTagsbody.Add("key", "value");
               req.Body = new AddDataParam()
               {
   // 替换为公网可以访问的图片地址
                   ImageUrl = "https://bucketname.obs.cn-north-4.myhuaweicloud.com/image/test1.jpg",
                   CustomNumTags = listCustomNumTagsbody,
                   CustomTags = listCustomTagsbody,
                   ItemId = "item_id"
               };
               try
               {
                   var resp = client.RunAddData(req);
                   var respStatusCode = resp.HttpStatusCode;
                   Console.WriteLine(respStatusCode);
               }
               catch (RequestTimeoutException requestTimeoutException)
               {
                   Console.WriteLine(requestTimeoutException.ErrorMessage);
               }
               catch (ServiceResponseException clientRequestException)
               {
                   Console.WriteLine(clientRequestException.HttpStatusCode);
                   Console.WriteLine(clientRequestException.RequestId);
                   Console.WriteLine(clientRequestException.ErrorCode);
                   Console.WriteLine(clientRequestException.ErrorMsg);
               }
               catch (ConnectionException connectionException)
               {
                   Console.WriteLine(connectionException.ErrorMessage);
               }
           }
       }
   }
   ```
   
2. 执行示例代码，控制台返回200即表示程序执行成功。
   ```
   200
   {
       "result": "success",
       "data": {
           "image_info": {
               "objects": [
                   {
                       "box": "135,489,1117,1341",
                       "category": 1,
                       "category_name": "top"
                   }
               ]
           }
       }
   }
   ```
