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：

using Microsoft.Office.Interop.Excel;

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

             object missing = 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

             int iCnt = 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。
