Question

在某些语言中，将项目添加到集合中时会有捷径。

我有以下内容：

Sub Main()

    Dim letters As List(Of String)
    letters = New List(Of String)

    letters.Add("a")
    letters.Add("1")
    letters.Add("2")
    letters.Add("3")
    letters.Add("x")
    letters.Add("d")

End Sub

是否有一种简便的方法来执行此操作。以下不起作用，但可能在VB.NET中有一些类似的语法：

Sub Main()

    Dim letters As List(Of String)
    letters = New List(Of String){"a","1","2","3","x","d"}

End Sub

Answer 1

从VS2010开始，您应该可以在VB.NET中执行此操作：

 Dim letters As List(Of String)
 letters = New List(Of String) From {"a","1","2","3","x","d"}

From可以换成括号：

 letters = New List(Of String) ({"a","1","2","3","x","d"})

Answer 2

您可以使用字符串数组（在我的示例中为input（））。另一个选项是将字符串列表传递给构造函数或使用List.AddRange。

    Dim input() As String = { "A", _
                              "B", _
                              "C" }

    Dim listA As New List(Of String)(input)

    dim listB as New List(Of String)
    listB.AddRange(input)
