c# - 检查哈希表是否具有字符串拆分中的特定值的最快方法

Question

任何帮助都会非常感谢。

例如，我有一个字符串

Dim words As String = "Hello world i fell like badword"
Dim inputCheck As String = words.Split(New Char() {" "c})

带有单词和替换单词的哈希表

您将如何遍历 hastable 并替换匹配的单词？

For Each Item In hsTable

                Next

结果将是“Hello world i fall like * ” 坏词被替换为哈希表中的替换词匹配。

谢谢你。

Answer 1

Pretty straightforward.

dim result as new list(of string) 
for each word in inputCheck
  result.Add if(hsTable.Keys.Contains(word), hsTable(word), word)
next
dim replaced = string.Join(" ", result)

Answer 2

您使用哈希表的任何特殊原因？使用 KeyValuePair 列表很容易做到这一点。像这样的东西会起作用吗？

Dim words As String = "Hello world i fell like badword"

Dim newWords As New List(Of KeyValuePair(Of String, String))
newWords.Add(New KeyValuePair(Of String, String)("badword", "goodword"))
newWords.Add(New KeyValuePair(Of String, String)("badword2", "goodword2"))

newWords.ForEach(Function(w) words.Replace(w.Key, w.Value))
