@rougedao Your question is pretty vague. Looks like you are trying to execute ListObject S3 operation. Could you provide more details like:

• Version of AWS SDK for .NET used
• Targeted .NET Platform (.NET Framework or .NET Core) and Version
• Reproduction Steps with sample code.
• Operating System and version

Thanks,
Ashish
