我想从ArrayList中检索对象数据;
public class Form1
{
ArrayList list = new ArrayList();
private void OnSockMessage(object sender, SockEventArgs e)
{
Regex MyRegex = new Regex("^[<][A-Za-z]");
if (e.SockMsg != null)
{
string y = e.SockMsg.ToString();
if (MyRegex.IsMatch(y) == true)
{
rrr = y;
string ipdd = SocClient[e.SocketRef].Soc.RemoteEndPoint.ToString();
//serverkey seckey;
list.Add(new serverkey(ipdd,rrr));
}
else
{
string curipadd = SocClient[e.SocketRef].Soc.RemoteEndPoint.ToString();
for (int i = 0; i < list.Count-1; i++)
{
//serverkey pk = list[i] as serverkey;
//string jj = list[i].ToString();
// serverkey pk = new serverkey(list[i].ToString());
/*********************************************
here i want to retrieve data from array list
*********************************************/
string ipadd;
if (curipadd == ipadd )
{
y = DecryptString(e.SockMsg, rrr);
listBox1.Items.Add(txtIP.Text + " <<" + y);
}
}
}
}
public class serverkey : Form1
{
string ipaddress;
string secertkey;
public serverkey(string IPAdd, string Seckey)
{
ipaddress = IPAdd;
secertkey = Seckey;
}
public string ip
{
get { return ipaddress; }
}
public string key
{
get { return secertkey; }
}
答案 0 :(得分:1)
最好使用强类型泛型List<serverkey>
和foreach循环而不是for循环。它会像
List<serverkey> list = new List<serverkey>();
//add your items as you already are
foreach(var item in list)
{
item.ip ...// use item as a serverkey
}
话虽如此,如果您出于某种原因可以使用通用,请使用“as”
ArrayList list = new ArrayList();
//add your items as you already are
foreach(var item in list)
{
var sk = item as serverkey;
sk.ip ...// use item as a serverkey
}
