我有2个列表集合。一个包含数字,其他名称。数字的名称是(总是)的两倍。我想从集合中获取第一个名称,然后从另一个集合中获取前两个数字,然后将它们放在第三个用户集合(VentriloUser)中。然后第二个名称需要与第3和第4个数字匹配,依此类推。
我正在考虑使用for或foreach循环,但我现在无法绕过它。
public class VentriloUser
{
public VentriloUser(string name, int seconds, int ping)
{
Name = name; Seconds = seconds; Ping = ping;
}
public string Name { get; set; }
public int Ping { get; set; }
public int Seconds { get; set; }
}
public class Ventrilo
{
public Ventrilo(string statusurl)
{
StatusURL = statusurl;
}
public string StatusURL { get; set; }
public string HTML { get; set; }
public List<VentriloUser> Users { get; set; }
private Regex findNumbers = new Regex("\\<td width=\"10%\" bgcolor=\"#\\w{6}\"\\>\\<font color=\"#000000\">\\<div style=\"overflow:hidden;text-overflow:ellipsis\"\\>-?\\d+\\<");
private Regex findNames = new Regex("\\<td width=\"20%\" bgcolor=\"#\\w{6}\"\\>\\<font color=\"#000000\">\\<div style=\"overflow:hidden;text-overflow:ellipsis\"\\>\\b\\w+\\<");
private WebClient wClient = new WebClient();
public void DownloadHTML()
{
HTML = wClient.DownloadString(StatusURL);
}
public List<int> GetNumbers()
{
var rawnumbers = findNumbers.Matches(HTML);
var numbers = new List<int>();
foreach (var rawnumber in rawnumbers)
{
var match = Regex.Match(rawnumber.ToString(), "\\>\\-?\\d+\\<");
string number = Regex.Replace(match.ToString(), "\\<|\\>", "");
numbers.Add(Convert.ToInt32(number));
}
return numbers;
}
public List<string> GetNames()
{
var rawnames = findNames.Matches(HTML);
var names = new List<string>();
foreach (var rawname in rawnames)
{
var match = Regex.Match(rawname.ToString(), "\\>\\w+<");
string name = Regex.Replace(match.ToString(), "\\<|\\>", "");
names.Add(name);
}
return names;
}
public List<VentriloUser> GenerateUsers()
{
var numbers = GetNumbers();
var names = GetNames();
var users = new List<VentriloUser>();
}
}
我是一个爱好者,但希望有一天能够追求事业。任何帮助深表感谢。谢谢你的时间。

使用LINQ:
var users = names.Select((name,idx) => new VentriloUser(name, numbers[idx*2], numbers[idx*2+1]))
.ToList();
使用循环:
var users = new List<VentriloUser>();
for (int i = 0; i < names.Count; i++)
{
var name = names[i];
int j = i * 2;
if (j >= numbers.Count - 1)
break; // to be safe...
users.Add(new VentriloUser(name, numbers[j], numbers[j + 1]));
}
