废话不多 直接上代码，上面是页面代码
//开始抽奖 private void DrawStart()
{

StringBuilder sb = new StringBuilder();
foreach (DataRow r in dt.Rows)
{
sb.Append("<li><div class=‘divName‘>" + r["UserName"].ToString() + "</div></li>");
sb.Append("<li><div class=‘divCompany‘>" + r["Company"].ToString() + "</div></li>");
}
UserList = sb.ToString();
}//停止抽奖
private void DrawEnd()
{
var dt = GstOneAndDraw().Tables[0];
StringBuilder sb = new StringBuilder();
foreach (DataRow r in dt.Rows)
{
sb.Append("<li><div class=‘divName‘>" + r["UserName"].ToString() + "</div>");
sb.Append("<div class=‘divCompany‘>" + r["Company"].ToString() + "</div></li>");
}
UserList = sb.ToString();
}
//获取抽奖人员列表 随机获取100人的数据
private DataSet GstList()
{
using (SqlConnection connection = new SqlConnection(connectionString))
{
DataSet ds = new DataSet();
try
{
connection.Open();
var SQLString = "select top 100 * from [T_PhoneNo] where [HasDraw]=0 order by newid()";

}
catch (System.Data.SqlClient.SqlException ex)

return ds;
}
}

{

SqlCommand com = new SqlCommand(sqlstr, connection);
int j = com.ExecuteNonQuery();
if (j > 0)
{ }
}
}
catch (System.Data.SqlClient.SqlException ex)
{
throw new Exception(ex.Message);
}
return ds;
}
}
//点击抽奖事件

后台代码如上，献丑了，直接用的ADO.NET，同事给的项目 我只是实现了这个功能，大家见笑了
