I am tired of all these \"upload to S3\" examples and tutorials that don\'t work , can someone just show me an example that simply works and is super easy?

Answer 1

I have written a tutorial about this.

Uploading a file to S3 bucket using low-level API:

IAmazonS3 client = new AmazonS3Client("AKI...access-key...", "+8Bo...secrey-key...", RegionEndpoint.APSoutheast2);  

FileInfo file = new FileInfo(@"c:\test.txt");  
string destPath = "folder/sub-folder/test.txt"; // <-- low-level s3 path uses /
PutObjectRequest request = new PutObjectRequest()  
{  
    InputStream = file.OpenRead(),  
    BucketName = "my-bucket-name",  
    Key = destPath // <-- in S3 key represents a path  
};  
  
PutObjectResponse response = client.PutObject(request); 

Uploading a file to S3 bucket using high-level API:

IAmazonS3 client = new AmazonS3Client("AKI...access-key...", "+8Bo...secrey-key...", RegionEndpoint.APSoutheast2);  

FileInfo localFile = new FileInfo(@"c:\test.txt");  
string destPath = @"folder\sub-folder\test.txt"; // <-- high-level s3 path uses \
 
S3FileInfo s3File = new S3FileInfo(client, "my-bucket-name", destPath);  
if (!s3File.Exists)  
{  
    using (var s3Stream = s3File.Create()) // <-- create file in S3  
    {  
        localFile.OpenRead().CopyTo(s3Stream); // <-- copy the content to S3  
    }  
}
