VB .NET 二维数组结构列表

Question

我需要在一维数组中存储一些结构体的二维数组，即：

Public Structure CodeBlock
    Public R As Integer
    Public C As Integer
    Public text_tx As String
    Public text_bx As String
    Public selected As Boolean
End Structure

Public code(nrows, ncols) As CodeBlock

Public history(5) As List(Of code) '<-- the problem

Answer 1

它告诉你“类型代码未定义”，所以你需要做的就是为Code创建一个类。

也许你的意思是这样的：

Public history As List(Of Code)

Public Structure CodeBlock
    Public R As Integer
    Public C As Integer
    Public text_tx As String
    Public text_bx As String
    Public selected As Boolean
End Structure

Public Class Code

    Public Property Stuff As CodeBlock(,)

    Public Sub New()
        ' Empty constructor
    End Sub

    Public Sub New(nRows As Integer, nCols As Integer)
        Stuff = New CodeBlock(nRows - 1, nCols - 1) {}
    End Sub

End Class

Sub Main()
    Dim cb = New Code(1, 2)
    Dim c = New CodeBlock With {.R = 1, .C = 2, .text_tx = "A", .text_bx = "B", .selected = False}
    cb.Stuff(0, 0) = c

    history = New List(Of Code)
    history.Add(cb)

End Sub
