c# - 如何上传内存文件到amazon S3？

Question

我想从我的 memoryStream 上传一个文件到 amazon S3 服务器。

代码如下:

public static bool memUploadFile(AmazonS3 client, MemoryStream memFile, string toPath)
{

    try
    {
        Amazon.S3.Transfer.TransferUtility tranUtility = new Amazon.S3.Transfer.TransferUtility(client);
        tranUtility.Upload(filePath, toPath.Replace("\\", "/"));

        return true;
    }
    catch (Exception ex)
    {
        return false;
    }

}

然后错误说，

“'Amazon.S3.Transfer.TransferUtility.Uplaod(string,string)' 的最佳重载方法匹配有一些无效参数”

查看Upload Method (stream, bucketName, key)

public static bool memUploadFile(AmazonS3 client, MemoryStream memFile, string toPath)
{
    try
    {
        using(Amazon.S3.Transfer.TransferUtility tranUtility =
                      new Amazon.S3.Transfer.TransferUtility(client))
        {
            tranUtility.Upload(memFile, toPath.Replace("\\", "/"), <The key under which the Amazon S3 object is stored.>);

            return true;
        }
    }
    catch (Exception ex)
    {
        return false;
    }
}
