我已成功创建了用户,凭据和存储桶.
现在我需要向该用户授予存储桶访问权限.

有没有办法从代码中获取此CanonicalUser值？
IAM用户对象仅提供ARN,Path,UserId和UserName值,但这些值均不适用于授权.

using (var s3 = new Amazon.S3.AmazonS3Client("[user_key]", "[secret_user_key]", RegionEndpoint.GetBySystemName("eu-west-1")))
{
    var response = s3.GetACL("[bucket_id]");
    var acl = response.AccessControlList;
    acl.AddGrant(
        new S3Grantee() { 
            CanonicalUser = **???** 
        }, 
        new S3Permission(S3Permission.FULL_CONTROL)
    );
    s3.PutACL(
        new PutACLRequest() { 
            AccessControlList = acl, 
            BucketName = "[bucket_id]" 
        }
    );
}

有没有办法在ServiceStack.OrmLite中返回表的子集？
就像是:

public class MyStuff
{
    public Guid Id { get; set; }
    public string Name { get; set; }
    public byte[] Data { get; set; } // Some large blob, which is not desired in the list
}

var somestuff = db.Select<MyStuff>(x => new { Id = x.Id, Name = x.Name });

我真的希望避免手动的东西,比如"从某个地方选择blabla"......
