我有以下课程:
Public Class titlesclass
Public Property Link As String
Public Property Title As String
Public Function Clear()
Link.Distinct().ToArray()
Title.Distinct().ToArray()
End Function
End Class
以下代码:
For Each title As Match In (New Regex(pattern).Matches(content)) 'Since you are only pulling a few strings, I thought a regex would be better.
Dim letitre As New titlesclass
letitre.Link = title.Groups("Data").Value
letitre.Title = title.Groups("Dataa").Value
lestitres.Add(letitre)
'tempTitles2.Add(title.Groups("Dataa").Value)
Next
我尝试使用简单的方法删除重复的字符串
Dim titles2 = lestitres.Distinct().ToArray()
调用类函数:
lestitres.Clear()
但这两个命题都不起作用,我知道我错过了一些非常简单的东西,但仍然找不到它是什么
答案 0 :(得分:2)
更容易使用已经实现IComparable
的类:
Dim query = From title In Regex.Matches(content, pattern).Cast(Of Match)
Select Tuple.Create(title.Groups("Data").Value, title.Groups("Dataa").Value)
For Each letitre In query.Distinct
Debug.Print(letitre.Item1 & ", " & letitre.Item2)
Next
Dim query = From title In Regex.Matches(content, pattern).Cast(Of Match)
Select New With {Key .Link = title.Groups("Data").Value,
Key .Title = title.Groups("Dataa").Value}
For Each letitre In query.Distinct
Debug.Print(letitre.Link & ", " & letitre.Title)
Next
