Question

我正在尝试通过下面的代码打开excel，但是在网上出现错误：

字符串excelFile = @“‪‪D：\ Hello.xlsx”; 工作簿xlWorkbook =（工作簿）xlApp.Workbooks.Open（excelFile）;

Excel版本：MS Office Professional plus 2016

错误： ExcelHighlight.exe中发生了类型为'System.Runtime.InteropServices.COMException'的未处理异常附加信息：对不起，我们找不到‪‪D：\ Hello.xlsx。是否有可能被移动，重命名或删除？

代码：

尝试

        {
            string FullPath = System.IO.Path.GetFullPath("Words.xml");
            string[] arr = XDocument.Load(FullPath).Descendants("Highlight").Descendants().Select(x => x.ToString()).ToArray();

            Application xlApp = new Application();
            string excelFile = @"‪‪D:\Hello.xlsx";
            Workbook xlWorkbook = (Workbook)xlApp.Workbooks.Open(excelFile);
            Sheets sheet = xlWorkbook.Worksheets;
            string str;
            int rCnt = 0;
            int cCnt = 0;

            Worksheet xlWorkSheet4;
            Range range;
            xlWorkSheet4 = (Worksheet)sheet.get_Item(1);
            Range last3 = xlWorkSheet4.Cells.SpecialCells(XlCellType.xlCellTypeLastCell, Type.Missing);
            range = xlWorkSheet4.get_Range("A1", last3);
            for (rCnt = 1; rCnt <= range.Rows.Count; rCnt++)

                for (cCnt = 1; cCnt <= range.Columns.Count; cCnt++)
                {
                    if (range.Cells[rCnt, cCnt].Value2 is string)
                    {
                        str = (string)(range.Cells[rCnt, cCnt] as Range).Value2;
                        if (str == null)
                        {
                            Console.WriteLine("null");
                        }
                        else
                        {
                            str.Replace("\\", "");
                            string[] words = str.Split(' ');
                            foreach (string arrs in arr)
                            {
                                foreach (string word in words)

                                    {

                                        var cell = (range.Cells[rCnt, cCnt] as Range);

                                        cell.Font.Bold = 1;
                                        cell.Font.Color = ColorTranslator.ToOle(Color.Red);
                                    }
                                }
                            }
                        }
                    }
                    else
                    {
                        Console.WriteLine("not string");
                    }
                }
            }
        }
        finally
        {

        }
    }

尝试将代码中指定的字符串传递给Process.Start方法。如果仍然找不到文件，则需要检查文件扩展名，并从开头删除@符号（删除逐字字符串），并改用以下路径：

string excelFile = "‪‪D:\\Hello.xlsx";

提供异常的Workbooks.open方法-System.Runtime.InteropServices.COMException
