Response输出excel设置文本样式

在网上查了些Response导出excel然后设置样式的方法，发现没有一个可行的于是开始自己研究，

发现可以通过输出样式的方式进行配置,我要设置的是全文本格式在excel样式是这样的mso-number-format:"\@"

于是我对Response输出进行了完善

Response.Clear();
Response.BufferOutput = true;
string style = "<style> td{ mso-number-format:\"\\@\" } </style> ";
//设定输出的字符集
Response.Charset = "GB2312";
//假定导出的文件名为FileName.xls
Response.AppendHeader("Content-Disposition", "attachment;filename= tiaoma.xls");
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
//设置导出文件的格式
Response.ContentType = "application/ms-excel";

EnableViewState = false;

System.Globalization.CultureInfo cultureInfo = new System.Globalization.CultureInfo("ZH-CN", true);
System.IO.StringWriter stringWriter = new System.IO.StringWriter(cultureInfo);

System.Web.UI.HtmlTextWriter textWriter = new System.Web.UI.HtmlTextWriter(stringWriter);

GridView gv = new GridView();
gv.DataSource = Session["table"] as DataTable;
gv.DataBind();
gv.RenderControl(textWriter);

Response.Write(style);
Response.Write(stringWriter.ToString());
Response.End();

成功的实现了Response输出并设置excel样式的效果
