Question

我开发了从excel读取的winform应用程序并将其转换为文本文件。我使用Microsoft.Office.Interop.Excel库来使用Excel。

这是我的代码：

private Excel.Application excel = null;
        private Excel.Sheets sheets = null;
        private Excel.Workbook excelWorkbook = null;
        private Excel.Workbooks excelWorkbooks = null;
        private Excel._Worksheet worksheet = null;
        private Excel.Range usedRange = null;    

        public ExcelFacade() { }

        public ExcelFacade(string fileName)
        {
            excel = new Excel.Application(); 

            excelWorkbooks = excel.Workbooks;
            excelWorkbook = excelWorkbooks.Open(fileName, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0); 
            sheets = excelWorkbook.Sheets;
        }

使用Excel完成工作后，我调用next方法（来自here）：

 public void Dispose()
        {


            foreach (Microsoft.Office.Interop.Excel.Worksheet sheet in sheets)
            {
                while (Marshal.ReleaseComObject(sheet) != 0) { }
            }

            excelWorkbook.Close();
            excelWorkbooks.Close();
            excel.Quit();

            var chromeDriverProcesses = Process.GetProcesses().
                         Where(pr => pr.ProcessName.ToLower().Contains("excel"));
            foreach (var process in chromeDriverProcesses)
            {
                process.Kill();
            }


            //while (Marshal.ReleaseComObject(usedRange) != 0) { }
            //while (Marshal.ReleaseComObject(worksheet) != 0) { }
            while (Marshal.ReleaseComObject(sheets) != 0) { }
            while (Marshal.ReleaseComObject(excelWorkbook) != 0) { }
            while (Marshal.ReleaseComObject(excelWorkbooks) != 0) { }
            //while (Marshal.ReleaseComObject(excel.Application) != 0)
            //{ }
            while (Marshal.ReleaseComObject(excel) != 0) { }         
            usedRange = null;
            worksheet = null;
            excelWorkbook = null;
            excelWorkbooks = null;
            sheets = null;
            excel = null;

            GC.Collect();
            GC.WaitForPendingFinalizers();
            GC.Collect();
            GC.WaitForPendingFinalizers();

        }
    }

但是，如果我更改excel并重新运行我的应用程序，应用程序不会更新更新的excel，它看起来像是从旧的excel读取的。这种行为看起来像缓存，我不知道如何禁用它。

如果我在代码中更改了某些内容，例如，白色空间，并重建应用程序，它的工作辉煌，并采取正确的Excel文件。有什么建议吗？

正如@ vbnet3d所说，使用ClosedXML库解决了所有问题

禁用Winform应用程序缓存
