在ASP.NET 2.0中，有时候需要对ASP.NET生成的HTML代码进行处理，或者是保存成静态文件。

在ASP.NET 2.0中，有时候需要对ASP.NET生成的HTML代码进行处理，或者是保存成静态文件。ASP.NET 提供了直接将请求保存成文件的方法：HttpRequest.SaveAs方法。下面这个方法就是在ASP.NET 2.0中得到ASP.NET生成的HTML代码，同时，生成一个静态文件的方法。

C#

// 计算数据，完全可以从数据看取得
ICollection CreateDataSource( )
{
System.Data.DataTable dt = new System.Data.DataTable();
System.Data.DataRow dr;
dt.Columns.Add(new System.Data.DataColumn("学生班级", typeof(System.String)));
dt.Columns.Add(new System.Data.DataColumn("学生姓名", typeof(System.String)));
dt.Columns.Add(new System.Data.DataColumn("语文", typeof(System.Decimal)));
dt.Columns.Add(new System.Data.DataColumn("数学", typeof(System.Decimal)));
dt.Columns.Add(new System.Data.DataColumn("英语", typeof(System.Decimal)));
dt.Columns.Add(new System.Data.DataColumn("计算机", typeof(System.Decimal)));

for (int i = 0 ; i ＜ 50 ; i++)
{
System.Random rd = new System.Random(Environment.TickCount * i); ;
dr = dt.NewRow();
dr[0] = "班级" + i.ToString();
dr[1] = "【孟子E章】" + i.ToString();
dr[2] = System.Math.Round(rd.NextDouble() * 100, 2);
dr[3] = System.Math.Round(rd.NextDouble() * 100, 2);
dr[4] = System.Math.Round(rd.NextDouble() * 100, 2);
dr[5] = System.Math.Round(rd.NextDouble() * 100, 2);
dt.Rows.Add(dr);
}
System.Data.DataView dv = new System.Data.DataView(dt);
return dv;
}

{
GridView1.DataSource = CreateDataSource();
GridView1.DataBind();
