方式三:其实与方式二类似,不同的是方式三如果事先已经知道DataGrid中绑定的是某个二维数组的话,我们可以避免再次访问数据库,这种做法更加高效.而且这样可以屏蔽那些不需要导出的列.

if (dgrid.Visible==false)

{

daochumsg.Visible=true; daochumsg.Text="您还没有确认导出的内容,请先查找";

}

else

{ daochumsg.Visible=false;

Response.Clear (); Response.Buffer = true; Response.Charset = "gb2312"; Response.AppendHeader("Content-Disposition","attachment;filename=CPKForms.xls");

Response.ContentEncoding=System.Text.Encoding.GetEncoding("gb2312");

Response.ContentType = "application/ms-excel"; this.EnableViewState = false;

System.IO.StringWriter oStringWriter = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter oHtmlTextWriter=new System.Web.UI.HtmlTextWriter(oStringWriter);

GC.Collect ();

StringWriter sw=new StringWriter();

sw.WriteLine("测试项目/t实际最小值/t实际最大值/t平均值/t标准值下限/t标准值上限/tSigam值/tCpk值");

// foreach(DataRow dr in dt.Rows)

for(int i=0;i<=shijihangshu;i++)

{

sw.WriteLine(storedata2[i,0]+"/t"+storedata2[i,1]+"/t"+storedata2[i,2]+"/t"+storedata2[i,3]+"/t"+storedata2[i,4]+"/t"+storedata2[i,5]+"/t"+storedata2[i,6]+"/t"+storedata2[i,7]);

}

sw.Close(); Response.Write(sw); Response.End();

}
