.NET-SDK之如何实现快速入门(二)?

示例程序


下面是一个完整的程序，演示了创建存储空间，设置存储空间ACL，查询存储空间的ACL，上传文件，下载文件，查询文件列表，删除文件，删除存储空间等操作。using System;using System.Collections.Generic;using Aliyun.OSS;namespace TaoYe{/// <summary>/// 快速入门示例程序/// </summary>public static class SimpleSamples{private const string _accessKeyId = "<your AccessKeyId>";private const string _accessKeySecret = "<your AccessKeySecret>";private const string _endpoint = "<valid host name>";private const string _bucketName = "<your bucket name>";private const string _key = "<your key>";private const string _fileToUpload = "<your local file path>";private static OssClient _client = new OssClient(_endpoint, _accessKeyId, _accessKeySecret);public static void Main(string[] args){CreateBucket();SetBucketAcl();GetBucketAcl();PutObject();ListObjects();GetObject();DeleteObject();// DeleteBucket();Console.WriteLine("Press any key to continue . . .
