今天研究一下导出excel表格，在网上看了看别人的代码，自己也写了一个小例子。
DProjectLedgerdpl = new DProjectLedger();
MProjectLedger mp = new MProjectLedger();
if (StringUtil.GetQueryString("projectnumber") != "")
{
mp.projectnumber = Server.UrlDecode(StringUtil.GetQueryString("projectnumber"));
}
if (StringUtil.GetQueryString("pname") != "")
{
mp.projectname = Server.UrlDecode(StringUtil.GetQueryString("pname"));
}
if (StringUtil.GetQueryString("sgdz") != "")
{
mp.sgdz = Server.UrlDecode(StringUtil.GetQueryString("sgdz"));
}
if (StringUtil.GetQueryString("sgdw") != "")
{
mp.constructionUnit = Server.UrlDecode(StringUtil.GetQueryString("sgdw").TrimEnd(','));
}
if (StringUtil.GetQueryString("sgqy") != "")
{
mp.constructionArea = Server.UrlDecode(StringUtil.GetQueryString("sgqy"));
}
if (StringUtil.GetQueryString("zyxf") != "")
{
mp.zyxf = Server.UrlDecode(StringUtil.GetQueryString("zyxf"));
}
if (StringUtil.GetQueryString("progress") != "")
{
mp.progress = Server.UrlDecode(StringUtil.GetQueryString("progress"));
}
string years = "";
if (Request.QueryString["years"] != null)
{
years = Request.QueryString["years"];
}
if (years == "")
{
years = DateTime.Now.ToString("yy");
}
mp.sgdzname = years;
if (Request.QueryString["htkgrqs"] != null)
{
mp.htkgrqs = Request.QueryString["htkgrqs"];
}
if (Request.QueryString["htkgrqz"] != null)
{
mp.htkgrqz = Request.QueryString["htkgrqz"];
}

}

{
mp.htjgrqz = Request.QueryString["htjgrqz"];
}
mp.id = StringUtil.GetQueryInt("sort");

}
}

}
//读取数据库
DataTable dt = dpl.GetToEduce(column, mp, tys, cont);
for (int j = 0; j < dt.Rows.Count; j++)

String filename = string.Format("{0}{1}.xls", "saleranklist", Convert.ToDateTime(DateTime.Now).ToString("yyyyMMdd")); //文件默认命名方式，可以自定义
Response.ContentType = "application/ms-excel;charset=utf-8";
Response.AddHeader("content-disposition", "attachment; filename=" + filename);
System.IO.MemoryStream memStream = workbook.SaveToStream();
Response.BinaryWrite(memStream.ToArray());
Response.End();
