推荐答案

这篇文章的开始使用Amazon S3 是一个很好的起点为您服务。在code位引用的ListObject方法是做99％你想要什么（获得与特定的preFIX所有文件）。你只需要添加位询问每个文件的大小，并把它们加起来。

The article Beginning with Amazon S3 is a good starting point for you. The code bits referencing the listObject method are doing 99% of what you want (getting all files with a particular prefix). You just need to add the bits to interrogate the file size of each and add them up.

如果你能得到桶，那么你已经拥有你所需要的这个片段的工作线了：

If you're able to get the bucket, then you already have all the wire up you need for this snippet to work:

using (s3Client)
{

    long totalFileSize = 0;

    try
    {        
        ListObjectsRequest Lor = new ListObjectsRequest()
        {
            BucketName = "<Your Bucket Name>",
            Prefix = "<Your Folder Path>",
            ///assuming your delimiter is a /
            Delimiter = "/" 
        };  

        ListObjectsResponse response1 = s3Client.ListObjects(Lor);

        foreach (S3Object s3Object in response1.S3Objects)
        { 
            totalFileSize += s3Object.Size();
        }
    }

    catch (AmazonS3Exception ex)
    {
        ///do some error handling....
    }
}
