Question

打开一个已有的EXCEL文件,并往里写入数据,却没有保存成功,同样的代码在自己机器上保存成功了,但在客户的服务器上却没有保存成功.代码如下:
Object oMissing = System.Reflection.Missing.Value;  //实例化参数对象
oExcel = new Excel.Application();   //初始化Excel.Application对象
oBook = oExcel.Workbooks.Open(filename,oMissing,oMissing,oMissing,oMissing,oMissing,oMissing,oMissing, oMissing,oMissing,oMissing,oMissing, oMissing, oMissing, oMissing);   //逐行写入数据，数组中前五行列标题，忽略,EXCEl中的行列号是从1开始
oExcel.Cells[1,1]="'一、";
.....
oBook.Saved = true;    
oExcel.UserControl = false;
oBook.Save();
oExcel.Quit();
oMissing=null;
oBook=null;
oExcel=null;
GC.Collect ();

string destFileName=filename;
