我正在尝试在C＃中打开并加载Excel文件

Question

打开现有的Excel文件时，调试中不会发生错误。但是Excel无法打开并获取单元格的值。

我正在使用c＃。我更改了打开格式，但是结果是相同的。

检查的格式是一一检查所有Excel值并返回结果。

例如，如果总共有100行，则while语句将从1旋转到100，将程序的结果插入两列并保存。

        Excel.Application application = null;

            if(filePath==null)
            {
                MessageBox.Show("파일이 선택되지않았습니다.");
                throw new Exception("file is not exist");
            }
            application = new Excel.Application();
            wb = application.Workbooks.Open(filePath, 0, true, 5, "", "",
