C#动态数组实用实例解析
C#动态数组(ArrayList )应用可以说在C#开发中是十分常用的,那么具体的实用实例是如何实现的呢?具体的实现步骤和注意事项是什么呢?
下面就是一个C#动态数组实例:用绑定一个DataList的三层代码
C#动态数组之DAL 数据访问层代码:
//绑定IDList,显示所有人员列表
public DataSet SelectIDListAll()
{
string Str = "select p_number,p_name from t_people";
DataSet ds = new DataSet();
myCon = new SqlConnection(DAL.DALConfig.ConnectionString);
try
{
SqlDataAdapter mycomm = new SqlDataAdapter(Str,myCon);
mycomm.Fill(ds,"t_people");
return ds;
}
catch(Exception exc)
{
throw exc;
}
} C#动态数组之BLL业务层代码:
//绑定IDList,显示所有人员列表
public ArrayList SelectIDListAll()
{
DAL.TPeopleDao peopledao = new TPeopleDao();
DataSet ds = new DataSet();
ds = peopledao.SelectIDListAll();
// Creates and initializes a new ArrayList.
ArrayList myAL = new ArrayList();
for(int i=0;i<ds.Tables[0].Rows.Count;i++)
{
myAL.Add(ds.Tables[0].Rows[i][0].ToString() +
" " +ds.Tables[0].Rows[i][1].ToString() );
}
return myAL;
