C#中的EXCEL的查找操作

最重要的是，range.find之后还要用range.findnext，就可以遍历所有的查找到的数据

代码如下：

usingMicrosoft.Office.Interop.Excel;

Application myExcel = newApplication();//开启EXCEL 服务

            objectmissing = System.Reflection.Missing.Value;

            myExcel.Application.Workbooks.Open(strExcelPath, missing, missing, missing, missing, missing, missing,

                missing, missing, missing, missing, missing, missing, missing, missing);

            Workbook myBook = myExcel.Workbooks[1];//获取工作簿

            _Worksheet sheet = (Worksheet)myBook.Sheets["RP750PDF"];//获取sheet

            intiCnt = sheet.UsedRange.Count;

            Excel.Range rgUsed, rgFound;

            rgUsed = sheet.get_Range("A2:A10");//获取a2-10范围的梅子

            rgFound = (Excel.Range)rgUsed.Find("RP757c-", Type.Missing,//“RP757C-”即是要查找的字符串

                Excel.XlFindLookIn.xlValues,//查找值，或者xlFormulas查找公式等

                Excel.XlLookAt.xlPart,//这里用xlWhole返回的一直是空指针

                Excel.XlSearchOrder.xlByRows,//按行查找

                Excel.XlSearchDirection.xlNext,//建议就用xlNext

false,false);

            Range rgTmp = rgFound;

            do
            {
                var item = rgTmp.get_Value();
                int iRowNum = rgTmp.Row;
                int iColNum = rgTmp.Column;
                rgTmp = rgUsed.FindNext(rgTmp);
            } while (rgTmp.Address != rgFound.Address);//记录第一个找到的range地址，当下一个单元格的地址与第一个相同，则跳出。
