批量更新图片信息

调用UpdateImageInfos接口，完成批量更新图片信息功能。

接口参数和返回字段请参见UpdateImageInfos。调用示例如下：

using System;
using Aliyun.Acs.Core;
using Aliyun.Acs.Core.Exceptions;
using Aliyun.Acs.vod.Model.V20170321;

namespace Aliyun.Acs.vod.Sdk.UpdateImageInfos
{
    class MainClass
    {
        public static void Main(string[] args)
        {
            try
            {
                // 构造请求
                UpdateImageInfosRequest request = new UpdateImageInfosRequest();

                request.UpdateContent = "[{\"ImageId\":\"ImageId1\",\"Title\":\"new Title\"},{\"ImageId\":\"ImageId2\",\"Description\":\"new Description\"}]";
                // 初始化客户端
                DefaultAcsClient client = InitVodClient("<Your AccessKeyId>", "<Your AccessKeySecret>");
                // 发起请求，并得到 response
                UpdateImageInfosResponse response = client.GetAcsResponse(request);
                Console.WriteLine("RequestId = " + response.RequestId);
                if (response.NonExistImageIds != null && response.NonExistImageIds.Count > 0)
                {
                    foreach (var imageId in response.NonExistImageIds)
                    {
                        Console.WriteLine("NonExist ImageId = " + imageId);
                    }
                }
            }
            catch (ServerException ex)

            }
        }
    }
}

获取图片信息

调用GetImageInfo接口，完成获取图片信息功能。

接口参数和返回字段请参见GetImageInfo。调用示例如下：

using System;
using Aliyun.Acs.Core;
using Aliyun.Acs.Core.Exceptions;
using Aliyun.Acs.vod.Model.V20170321;

namespace Aliyun.Acs.vod.Sdk.GetImageInfo
{
    class MainClass
    {
        public static void Main(string[] args)
        {
            try
            {
                // 构造请求
                GetImageInfoRequest request = new GetImageInfoRequest();
                // 图片ID
                request.ImageId = "ImageId";
                // 初始化客户端
                DefaultAcsClient client = InitVodClient("<Your AccessKeyId>", "<Your AccessKeySecret>");
                // 发起请求，并得到 response
                GetImageInfoResponse response = client.GetAcsResponse(request);
                // 打印本次请求ID
                Console.WriteLine("RequestId = " + response.RequestId);
                if (response.ImageInfo != null)
                {
                    Console.WriteLine("ImageId = " + response.ImageInfo.ImageId);
                    Console.WriteLine("ImageType = " + response.ImageInfo.ImageType);
                    Console.WriteLine("Title = " + response.ImageInfo.Title);
                }
            }
            catch (ServerException ex)
            {
                Console.WriteLine(ex.ToString());
            }

            {
                // 构造请求
                DeleteImageRequest request = new DeleteImageRequest();
                //根据ImageURL删除图片文件
                request.DeleteImageType = "ImageURL";
                request.ImageURLs = "http://192.168.0.0/16/cover.jpg";
                //根据ImageId删除图片文件
                //request.DeleteImageType = "ImageId";
                //request.ImageIds = "ImageId1,ImageId2";
                //根据VideoId删除指定ImageType的图片文件
                //request.DeleteImageType = "VideoId";
                //request.VideoId = "VideoId";
                //request.ImageType = "SpriteSnapshot";
                // 初始化客户端
                DefaultAcsClient client = InitVodClient("<Your AccessKeyId>", "<Your AccessKeySecret>");
                // 发起请求，并得到 response
                DeleteImageResponse response = client.GetAcsResponse(request);
                // 打印本次请求ID
