Deleting a file from a sub directory of an AWS S3 bucket using asp.net

I want to delete a file that resides on the path: bucket1/dir1/dir2/file.png

The code I have done:

public bool DeleteFileFromS3(string bucketName, string directoryInBucket, string subDirectoryInDirectory, string fileNameInS3) 
{
    IAmazonS3 client = new AmazonS3Client(RegionEndpoint.USEast2);
    var BucketName = "";

    if (directoryInBucket == "" || directoryInBucket == null)
    {
        BucketName = bucketName; //no subdirectory just bucket name  
    }
    else
    {   // subdirectory and bucket name  
        BucketName = bucketName + @"/" + directoryInBucket + @"/" + subDirectoryInDirectory;
    }

    var objectName = fileNameInS3;

    client.DeleteObject(BucketName, objectName); 

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

However, this doesn't work.

Upon some research, I found out that the AWS file system is different. It is object-based and the files are stored as objects with keys. However, I am unable to find an example that uses keys for a file that resides in the subdirectory of a bucket and then deletes it using them. Kindly suggest me something.

The BucketName should only contain the name of the bucket.

The ObjectName should include the name of the object, with the full path to the object.

For example:

  • BucketName = 'my-bucket'
  • ObjectName = 'invoices/january/foo.txt'

This is because Amazon S3 doesn't really have directories, even though it 'appears' to have them. The full path is part of the object name ('Key').
