推荐答案

这里是您必须遵循的说明才能获得一个完整的演示程序......

well here are the instruction that you have to follow to get a fully working demo program ...

1-下载并安装适用于 .NET 的亚马逊网络服务 SDK，您可以在 (http://aws.amazon.com/sdk-for-net/).因为我有 Visual Studio 2010，所以我选择安装 3.5 .NET SDK.

1-Download and install the Amazon web services SDK for .NET which you can find in (http://aws.amazon.com/sdk-for-net/). because I have visual studio 2010 I choose to install the 3.5 .NET SDK.

2- 打开 Visual Studio 并创建一个新项目，我有 Visual Studio 2010 并且我正在使用控制台应用程序项目.

2- open visual studio and make a new project , I have visual studio 2010 and I am using a console application project.

3- 添加对 AWSSDK.dll 的引用，它与上面提到的 Amazon Web Service SDK 一起安装，在我的系统中，dll 位于C:Program Files (x86)AWS SDK for .NETin"Net35AWSSDK.dll".

3- add reference to AWSSDK.dll , it is installed with the Amazon web service SDK mentioned above , in my system the dll is located in "C:Program Files (x86)AWS SDK for .NETinNet35AWSSDK.dll".

4- 创建一个新的类文件，在此处将其命名为AmazonUploader" 类的完整代码:

4- make a new class file ,call it "AmazonUploader" here the complete code of the class:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Amazon;
using Amazon.S3;
using Amazon.S3.Transfer;

namespace UploadToS3Demo
{
    public class AmazonUploader
    {
        public bool sendMyFileToS3(string localFilePath, string bucketName, string subDirectoryInBucket, string fileNameInS3)
        {
        // input explained :
        // localFilePath = the full local file path e.g. "c:mydirmysubdirmyfilename.zip"
        // bucketName : the name of the bucket in S3 ,the bucket should be alreadt created
        // subDirectoryInBucket : if this string is not empty the file will be uploaded to
            // a subdirectory with this name
        // fileNameInS3 = the file name in the S3

        // create an instance of IAmazonS3 class ,in my case i choose RegionEndpoint.EUWest1
        // you can change that to APNortheast1 , APSoutheast1 , APSoutheast2 , CNNorth1
        // SAEast1 , USEast1 , USGovCloudWest1 , USWest1 , USWest2 . this choice will not
        // store your file in a different cloud storage but (i think) it differ in performance
        // depending on your location
        IAmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client(RegionEndpoint.EUWest1);

        // create a TransferUtility instance passing it the IAmazonS3 created in the first step
        TransferUtility utility = new TransferUtility(client);
        // making a TransferUtilityUploadRequest instance
        TransferUtilityUploadRequest request = new TransferUtilityUploadRequest();

        if (subDirectoryInBucket == "" || subDirectoryInBucket == null)
        {
            request.BucketName = bucketName; //no subdirectory just bucket name
        }
        else
        {   // subdirectory and bucket name
            request.BucketName = bucketName + @"/" + subDirectoryInBucket;
        }
        request.Key = fileNameInS3 ; //file name up in S3
        request.FilePath = localFilePath; //local file name
        utility.Upload(request); //commensing the transfer

        return true; //indicate that the file was sent
    }
  }
}

5- 添加配置文件:在解决方案资源管理器中右键单击您的项目并选择添加"->新项目"，然后从列表中选择应用程序配置文件"类型并单击添加"按钮.一个名为App.config"的文件被添加到解决方案中.

5- add a configuration file : right click on your project in the solution explorer and choose "add" -> "new item" then from the list choose the type "Application configuration file" and click the "add" button. a file called "App.config" is added to the solution.

6- 编辑 app.config 文件:双击解决方案资源管理器中的app.config"文件，将出现编辑菜单.用以下文本替换所有文本:

6- edit the app.config file : double click the "app.config" file in the solution explorer the edit menu will appear . replace all the text with the following text :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="AWSProfileName" value="profile1"/>
    <add key="AWSAccessKey" value="your Access Key goes here"/>
    <add key="AWSSecretKey" value="your Secret Key goes here"/>

  </appSettings>
</configuration>

您必须修改上述文本以反映您的 Amazon Access Key Id 和 Secret Access Key.

you have to modify the above text to reflect your Amazon Access Key Id and Secret Access Key.

7- 现在在 program.cs 文件中(记住这是一个控制台应用程序)编写以下代码:

7- now in the program.cs file (remember this is a console application) write the following code :

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace UploadToS3Demo
{
    class Program
    {
        static void Main(string[] args)
        {
            // preparing our file and directory names
            string fileToBackup = @"d:mybackupFile.zip" ; // test file
            string myBucketName = "mys3bucketname"; //your s3 bucket name goes here
            string s3DirectoryName = "justdemodirectory";
            string s3FileName = @"mybackupFile uploaded in 12-9-2014.zip";

            AmazonUploader myUploader = new AmazonUploader();
            myUploader.sendMyFileToS3(fileToBackup, myBucketName, s3DirectoryName, s3FileName);
        }
    }
}

8- 用你自己的数据替换上面代码中的字符串

8- replace the strings in the code above with your own data

9- 添加纠错你的程序已经准备好了

9- add error correction and your program is ready
