windows窗口句柄mysqllist集合查询_将从mysql数据库查询的信息，遍历到List
以及⼀些随机数的。。。
将从mysql数据库查询的信息，遍历到List<>以及⼀些随机数的⽣成。
代码⽐较乱，但是⽅法还是对的，⼤家⼜需要的选择看，希望对博友 有帮助，欢迎留⾔分享！
public class subject { public string sub { get; set; } }
//public class QueryCategory {
// subject s = new subject();
// string m = s.sub;
// string Sql = "select Category from httang_test.hxwang_office where Subject = '" + m.ToString()+"";
// DataTable dt1 = MySqlDBHelper.QueryDataTable(Sql);
//}
static List GenerateTasks()
{
// List ShoppingTasks = new List();
// List OfficeTasks = new List();

TaskInfoControl t = new TaskInfoControl();
DataTable dt = t.QuerySubject();
foreach (DataRow item in dt.Rows)//循环取出ds.table中的值
{
subject s = new subject(); // 实例化subject对象
try

{
s.sub = Convert.ToString(item["Subject"]);//将表中Subject这列值给s.sub
}
catch (Exception e)
{
throw e;
}
HouseTasks.Add(s.sub); // 将取出的对象保存在LIST中 以上是获得值。
// ShoppingTasks.Add(s.sub);

}

TaskInfoControl tic = new TaskInfoControl();
DataTable hc = tic.QueryCaregory(m);
ts = Convert.ToString(hc); //将DataTable转换成string
}
//将string 转换成枚举类型
