System.IO WriteAllLines

[patrick]

In SYSTEM.IO, by using WriteAllLines, save csv file.
Is there a way to split multiple Sheets into one file and save them?

You need to provide much more detail than that. Firstly, presumably you mean the File.WriteAllLines method. Types exist in namespaces and methods exist in types. As for the rest, sheets of what? And you split one into multiple, not multi0ple into one. That's combining, not splitting. Please take the time and make the effort to provide a FULL and CLEAR explanation of the problem, so we don't have to guess or make assumptions.

Also, what does this have to do with Web Forms? The fact that code is in a Web Forms app doesn't make it a Web Forms question if nothing would change if it were in a different type of app. Please be clear what the specific connection to Web Forms is, or we will move it to a more appropriate forum.

Use a CSV writing library to write CSVs too! Rolling your own is a waste of resources

I don't think you have have multiple sheets in a single .CSV file.* See RFC 4180: Common Format and MIME Type for Comma-Separated Values (CSV) Files

*Given that the past two years, I've been seeing people making up their own "CSV" style file formats that don't conform with RFC4180, but they all call them "CSV files". Join the lemmings?
