Question

我可以将excel文件上传到AWS s3帐户吗？我所拥有的是，库中提供的PutObject方法可用于从某个位置或使用Stream对象上载文件。

PutObjectRequest request = new PutObjectRequest()
                {
                    ContentBody = "this is a test",
                    BucketName = bucketName,
                    Key = keyName,
                    InputStream = stream
                };

                PutObjectResponse response = client.PutObject(request);

键可以是机器上的绝对路径，也可以是文件流。但我怀疑的是我们如何使用上述方法上传excel文件

P.S 这是我用来将stream转换为byte []的方法，但input.ReadByte（）总是等于零。所以我怀疑，是不是在阅读excel文件？

FileStream str = new FileStream(@"C:\case1.xlsx", FileMode.Open);            
byte[] arr = ReadFully(str);


public static byte[] ReadFully(FileStream input)
        {
            long size = 0;
            while (input.ReadByte() > 0)
            {
                size++;
            }
            byte[] buffer = new byte[size];
            //byte[] buffer = new byte[16 * 1024];
            using (MemoryStream ms = new MemoryStream())
            {
                int read;
                while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
                {
                    ms.Write(buffer, 0, read);
                }
                return ms.ToArray();
            }
        }

您应该能够通过文件路径或流上传任何文件。它不是一个Excel文件并不重要。当您运行PutObject时，它会上传该路径或流所代表的实际文件数据。

您可以在Filext查看MS Office格式的MIME类型。按文件路径执行操作可能会更容易：

PutObjectRequest request = new PutObjectRequest()
{
    ContentBody = "this is a test",
    BucketName = bucketName,
    Key = keyName,
    ContentType =
 "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", // xlsx
    FilePath = @"\path\to\myfile.xlsx"
};

PutObjectResponse response = client.PutObject(request);

或者从文件流中读取：

PutObjectRequest request = new PutObjectRequest()
{
    ContentBody = "this is a test",
    BucketName = bucketName,
    Key = keyName,
    ContentType =
 "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet" // xlsx
};
using (var stream = new FileStream(@"\path\to\myfile.xlsx", FileMode.Open))
{
    request.InputStream = stream;

    PutObjectResponse response = client.PutObject(request);
}

我可以使用AWSSDK.dll将excel文件上传到Amazon S3
