How can I get the MIME types of objects in Amazon S3?

Is there a way to retrieve the MIME types of the objects in S3. I am trying to implement a solution in which I will be getting multiple objects from S3. Instead of using there key and then getting a sub string to calculate the MIME type, can I get the MIME type from Amazon S3 in some way? I am using cloud berry explorer pro and I know it let's you set the MIME type, but how do we retrieve this information using the AWS SDK for .NET or the REST API?
