//指定要操作的Sheet,两种方式:

//Excel.Worksheet xSheet=(Excel.Worksheet)xApp.ActiveSheet;
//读取数据,通过Range对象
Excel.Range rng1=xSheet.get_Range("A1",Type.Missing);

//写入数据

//保存方式一:保存WorkBook

//xSheet.SaveAs(@"D:\CData2.xls",Missing.Value,Missing.Value,Missing.Value,Missing.Value
//,Missing.Value,Missing.Value,Missing.Value,Missing.Value,Missing.Value);
//保存方式三
