Exception from HRESULT:0x800A03EC如何修改？？

[lubaixs]

在用模板导出excel时报错：Exception from HRESULT:0x800A03EC
具体的错误代码是：xBk = workbooks.Add(excelTemplateDPath);
各位大牛帮下忙。。。。实在不知道哪里的问题

各位有会的吗，帮个忙撒

Workbooks.Add method Workbook Add( Object Template ) Template Type: System.Object Optional Object. Determines how the new workbook is created. If this argument is a string specifying the name of an existing Microsoft Excel file, the new workbook is created with the specified file as a template. If this argument is a constant, the new workbook contains a single sheet of the specified type. Can be one of the following XlWBATemplate constants: xlWBATChart, xlWBATExcel4IntlMacroSheet, xlWBATExcel4MacroSheet, or xlWBATWorksheet. If this argument is omitted, Microsoft Excel creates a new workbook with a number of blank sheets (the number of sheets is set by the SheetsInNewWorkbook property). 你传入的string里面的路径上的文件可能不存在，或者无权访问。
