C# AWS.NET SDK多部分文件从Http上载

我已经实现了一个.ashx处理程序，它从客户端接收文件的分块上传部分。之前，我先将文件存储在临时文件夹中，然后再将其上载到AWS。 由于文件已经变得相当大，我想跳过临时文件夹部分，并使用多部分请求将它们直接上传到AWS

到目前为止，它看起来还不错，但我找不到一个重载来接受HttpPostedFile或流进行上传

我可以做如下的事情吗

        // Create request to upload a part.
        UploadPartRequest uploadRequest = new UploadPartRequest()
            .WithBucketName(myBucket)
            .WithKey(myKey)
            .WithUploadId(myUploadId)                
            .WithPartNumber(partNumber)
            .WithInputStream(inputStream);

简单：只需通过属性设置输入流：

            // Create request to upload a part.
            UploadPartRequest uploadRequest = new UploadPartRequest()
                .WithBucketName(myBucket)
                .WithKey(myKey)
                .WithUploadId(UploadId)
                .WithPartNumber(PartNumber)
                .WithPartSize(inputStream.Length)
                .WithFilePosition(FilePosition);

            uploadRequest.InputStream = inputStream;

WithInputStream将返回s3请求，而不是UploadPartRequest 因此，只需将返回类型强制转换为UploadPartRequest

// Create request to upload a part.
        UploadPartRequest uploadRequest = new UploadPartRequest()
            .WithBucketName(myBucket)
            .WithKey(myKey)
            .WithUploadId(myUploadId)                
            .WithPartNumber(partNumber);

uploadRequest = (UploadPartRequest)uploadRequest.WithInputStream(ftiObject.sourceStream); 

这对我有用

UploadPartRequest uploadRequest = new UploadPartRequest()
        .WithBucketName(myBucket)
        .WithKey(myKey)
        .WithUploadId(myUploadId)                
        .WithPartNumber(partNumber)
        .WithInputStream(stream) as UploadPartRequest;

这也是可能的
