推荐答案

正如你上次提到这个问题时被告知的那样：如何使用C＃在ASP.NET中的特定路径中保存excel [ ^ ]

As you were told the last time you asked this question: How to save excel in specific path in ASP.NET using C#[^]

ASP.NET is unable to interact with client machine folder structure, as it has only access to browser only.
that's why, When you download any file from web application it ask you for the path to store the file. You can not directly put/download file in client machine it may treat as malicious activity.
