vb.net - 关闭Excel.Workbook时出现COMException(0x80010108-RPC_E_DISCONNECTED)

当我运行以下代码时，出现以下异常：

''# NOTE: ExcelApp is a Private main form variable
Dim ReportBooks As Excel.Workbooks = ExcelApp.Workbooks
Dim ReportBook As Excel.Workbook = ReportBooks.Open(localFilename)
Dim ReportSheet As Excel.Worksheet = ReportBook.Sheets("Report")

''# Retreive data from sheet

ReleaseCOM(ReportSheet)
ReportBook.Close(True) ''# Error raised here
ReleaseCOM(ReportBook)
ReleaseCOM(ReportBooks)

ERROR:
COMException was unhandled
The object invoked has disconnected from its clients.
(Exception from HRESULT: 0x80010108 (RPC_E_DISCONNECTED))

注意：所有数据似乎已正确检索。

请帮助我诊断并克服此错误。

最佳答案

RPC_DISCONNECTED ...可怕的是“调用的对象已与其客户端断开连接。”问题。造成这种情况的原因很多，看来您已经使用Excel.解决了全局变量问题。您可以将第一个ReleaseCOM(ReportSheet)放在ReportBook(Close)下面并运行它吗？另外，请检出this。
