How to upload memory file to amazon S3?

Question

I want to upload a file from my memoryStream to amazon S3 server.

Here is the code:

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;
    }

}

Then the error says,

"the best overload method match for 'Amazon.S3.Transfer.TransferUtility.Uplaod(string,string)' has some invalid arguments"

Look at the 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;
    }
}
