在 vb.net 中是否有类似 "with" 的功能?

in vb.net is there something similar to "with" but for functions?

我连续用同一个函数,有没有办法像

with basicmove()
{(r),(u, 20),(r)
end with

而不是

    basicmove(r)
    basicmove(u, 20)
    basicmove(r)

编辑:或

        basicmove(l, 5)
    basicmove(d, 3)
    basicmove(l, 21)
    basicmove(u, 5)

不,这不可能。但是,如果参数是同一类型,则可以使用基本类型列表和 List.ForEach 或普通 For Each 循环:

moves.ForEach(Function(r) basicmove(r))

您可以创建一个具有适当属性的新 class 和一个 List(Of Move)

我不完全确定这是否解决了你所要求的一切,但也许它会给你一个想法。

编辑: 根据更新后的问题,我有另一个解决方案。这就需要在编程中理解two-dimensional arrays。您只需将所有 "coordinates" 加载到一个数组中,然后迭代它们并按照它们输入数组的相同顺序执行操作。

Sub Main()
    ' multi-dimensional array of moves (there are plenty of way to create this object if this is confusing)
    Dim myList(,) As Object = New Object(,) { _
                                {"l", 5}, _
                                {"d", 3}, _
                                {"l", 21}, _
                                {"u", 5} _
                            }

    ' iterate the array and perform the moves.
    For x As Integer = 0 To myList.GetUpperBound(0)
        ' getting coordinates from the first & second dimension
        basicmove(myList(x, 0), myList(x, 1))
    Next

    Console.ReadLine()
End Sub

Private Sub basicmove(ByVal a As String, ByVal b As Integer)
    Console.WriteLine("param1:" & a & ",param2:" & b)
End Sub

请原谅 c# 语法。这是未经测试的,因此可能存在错误。

public class myWith{
public List<Object> params{get;set;}
   public with(Action<Object> function){
      params.ForEach(p=>function(p));
   }     
}

使用的想法是:

new myWith(x=>doStuff(x)){
    params = new List<Object>{r, {u,20}, r}
}

希望这个想法能得到理解

这不是最漂亮的,尽管它可以使用隐式数组:

Private Sub MakeCalls()
    Dim r As Integer = 1 : Dim u As Integer = 2
    For Each o In {({r}), ({u, 20}), ({r})}
        basicmove(o)
    Next
End Sub     
Private Sub basicmove(params() As Integer)
    For Each i As Integer In params
        Debug.Print(i.ToString)
    Next
End Sub
