如何允许“。” 在使用后期绑定“另存为”时，在Excel文件名中？

Question

I just came up with this issue, we have a library that uses Reflection to manipulate Excel files. When a user is trying to save a file that has a . in the file name (eg: 01.02.xls ) it won't include .xls in the saved file (result: 01.02 ).

workbook.GetType().InvokeMember("SaveAs", BindingFlags.InvokeMethod, null, workbook, new Object[] { filepath.Remove(filepath.LastIndexOf(".")), 56 });

Is there an option that allows . inside the file name?

Answer 1

Why do you remove .xls from your filepath with

filepath.Remove(filepath.LastIndexOf("."))

I just tested this myself, if I use just filepath as in

workbook.GetType().InvokeMember("SaveAs", BindingFlags.InvokeMethod, 
null, workbook, new Object[] { filepath, 56 });

it works for me
