索引数超过索引数组 vb 的维数

Question

在我调用函数的行的 sub main 中，我遇到了一个我不知道如何解决的错误：

索引数超过索引数组的维数

Module Module1
    Sub main()
        Dim names() As String = {"heimdall", "hella", "loki", "thor", "tyr", "odin"} 'list in order
        Dim last As Integer = names.Length - 1
        Dim first As Integer = 0
        Dim player As String = "thor"

        search(names(), last, first, player)

    End Sub

    Function search(ByVal names() As String, ByVal last As Integer, ByVal first As Integer, ByVal player As String)
        Dim midpoint As Integer = (first + last) \ 2
        Dim found As Boolean = False

        While found = False
            If last < first Then
                Return -1
            End If

            If names(midpoint) > player Then
                Return search(names, last, first, midpoint)
                found = True
            Else
                Return midpoint
                found = True
            End If
        End While


        Return midpoint 'automatically does this when found = true

    End Function

End Module

Answer 1

将names() 末尾的括号传递给search 方法时删除它。只有在声明数组时才需要这些。

search(names, last, first, player)
