how to prevent C# from forcing excel file to open as read only?

Question

当我通过 System.Diagnostics.Process.Start 或 Microsoft.Office.Interop.Excel 打开 Excel(.xlsm) 时，文件被迫以只读模式启动，如何防止这种情况并以正常方式启动？

Answer 1

I think it isn't the problem System.Diagnostics.Process.Start . Because Your file is read-only already.

Try to force attribute of the file before opening it.

The is a lot of examples of codes to do that

IE

File.SetAttributes(fileExcelPath, attr & ~FileAttributes.ReadOnly);
