使用的代码段为:

I am using the Amazon SDK in Visual Studio. I am trying to upload files to the S3 location using the File.Copy command.

The AWS SDK provides a service to generate a pre-signed URL so that files can be uploaded or downloaded. I have this, but when I try to use it, and error is thrown. "Illegal Character". The last part of the URL is "%2FRFfYsyil%2BTsk%3D".

Try
    File.Copy(isrc, iDest, True)
