如何在C＃中搜索Excel文件
我正在使用的代码：
private void OpenExcelFile() { Excel.Application exlApp = new Microsoft.Office.Interop.Excel.Application(); if (exlApp == null) { MessageBox.Show("Excel app object could not be created"); } else { exlFileSelector.FileName = @"*.xls"; if (exlFileSelector.ShowDialog() == DialogResult.OK) { Excel.Workbook wrkBook = exlApp.Workbooks.Open(exlFileSelector.FileName, 0, true, 5, "", "", true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, true, true); Excel.Sheets sheetList = wrkBook.Sheets; Excel.Range search = exlApp.get_Range("A1", "C5"); search.Find("FindMe", null, Excel.XlFindLookIn.xlValues, Excel.XlLookAt.xlWhole, Excel.XlSearchOrder.xlByRows, Excel.XlSearchDirection.xlNext, false, null, null); } } } 这是“codex”回答此论坛中提出的上一个问题的答案。 但是当我将它复制到我的应用程序时，系统无法识别exlFileSelector.FileName 。 我该如何解决？ 我错过了什么？ 我一直在尝试在Excel文件中进行简单搜索，但没有运气。 （我添加了项目所需的Excel引用）。 谢谢。
我找到了这样的代码，我希望它有点帮助..

虽然老问题，但我会回答未来的读者… exlFileSelector.FileName只是您尝试阅读的Excel文件的文件路径。 将其替换为您要阅读的Excel文件的完整文件路径。
