Uploading a file on Amazon S3 using C#:

Step1)

 

Create a New Class with any name you want “CAmazon”

Create amazon API  client Like this, select your region carefully.

IAmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client(RegionEndpoint.USEast1);

Create a function to upload file on amazon s3 cloud.

public bool UploadFile(string localFilePath, string bucketName, string subDirectoryInBucket, string fileNameInS3)
{
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); // commencing the transfer

return true;
}

Step2)

Call the function from main()

static void Main(string[] args)
{
//Upload a file
string fileToUpload = @"D:\TestFile.txt"; // test file
string myBucketName = "punch-scraped-data"; //your s3 bucket name goes here
string s3DirectoryName = null; // your directory name in se bucket
string s3FileName = @"TestFile.txt"; //file name in s3 bucket
CAmazon myUploader = new CAmazon(); //object of class that contains function
bool b = myUploader.UploadFile(fileToUpload, myBucketName, s3DirectoryName, s3FileName);
if (b == true)
{
Console.WriteLine("Uploaded Successfully");
Console.ReadLine();
}
else
{
Console.WriteLine("Not Uploaded");
Console.ReadLine();
}
}

public bool DownloadFile(string file) //file is the file name in amazon s3 bucket
{
IAmazonS3 client2;
using (client2 = new AmazonS3Client(Amazon.RegionEndpoint.USEast1))
{
GetObjectRequest request = new GetObjectRequest
{
BucketName = "punch-scraped-data",
Key = file
};
using (GetObjectResponse response = client2.GetObject(request))
{
string dest = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), file);
if (!File.Exists(dest))
{
response.WriteResponseStreamToFile(dest);
}
}
}
return true;
}

Step2)

Call the function from main()

static void Main(string[] args)
{
//Download a file
CAmazon myUploader = new CAmazon();
bool b = myUploader.DownloadFile("TestFile.txt");
if (b == true)
{
Console.WriteLine("downloaded Successfully");
Console.ReadLine();
}
else
{
Console.WriteLine("Not Downloaded");
Console.ReadLine();
}
}

 

Delete a file from Amazon S3 bucket using C#:

Create a function in separate class named “CAmazon” to delete file from amazon s3 cloud.

public bool DeleteFile(string file)
{
string accessKeyID = System.Configuration.ConfigurationManager.AppSettings["AWSAccessKey"];
string secretAccessKeyID = System.Configuration.ConfigurationManager.AppSettings["AWSSecretKey"];
IAmazonS3 client3;
client3 = new AmazonS3Client(Amazon.RegionEndpoint.USEast1);
DeleteObjectRequest deleteObjectRequest =
new DeleteObjectRequest
{
BucketName = "punch-scraped-data",
Key = file
};
using (client3 = Amazon.AWSClientFactory.CreateAmazonS3Client(accessKeyID, secretAccessKeyID,Amazon.RegionEndpoint.USEast1))
{
client3.DeleteObject(deleteObjectRequest);
}
return true;
}

Step2)

Call the function from main()

static void Main(string[] args)
{
//Delete a File
CAmazon myUploader = new CAmazon();
bool b = myUploader.DeleteFile("TestFile.txt");
if (b == true)
{
Console.WriteLine("deleted Successfully");
