DataTable dsmf = dbmyfile.GetDataTable("SELECT Title,FSize,Checkcode,Uploadtime FROM myfile WHERE UserID=" + UserID);
List mfm = new List();
foreach (DataRow dr in dsmf.Rows)
{
myfilemodel mfmd=new myfilemodel();
mfmd.Title = dr["Title"].ToString();
mfmd.FSize = (float)System.Convert.ToDouble(dr["FSize"].ToString());
mfmd.Checkcode = dr["Checkcode"].ToString();
mfmd.Uploadtime = Convert.ToDateTime(dr["Uploadtime"]);
mfm.Add(mfmd);
}
return mfm;

1、实现在页面添加GridView控件
2、动态添加GridView控件到页面

 this.Controls.Add(gv);
