Arrays 将字符串拆分为数组时出错

基本上，我不能修剪它，除非它在一个消息框。。这很难解释。 以下是两张图片： 1. 2.

这很有效^^^^

这并不是：

        Dim value As String = ary(0).Trim()
       this is the error---> Dim value1 As String = ary(1).Trim()

        Dim R As String
        Dim G As String
        Dim B As String

        Dim outline As String
        Dim outlineColor As String


        R = Chr(34) & "MouseColorR" & Chr(34)
        G = Chr(34) & "MouseColorG" & Chr(34)
        B = Chr(34) & "MouseColorB" & Chr(34)

        outline = Chr(34) & "ThickMouseEdges" & Chr(34)
        outlineColor = Chr(34) & "ThickMouseEdgesPackedColor" & Chr(34)
        'based on the value after the equals sign, do something



        If value = R Then
            MsgBox(ary(1).Trim(Chr(44)))

        ElseIf value = G Then
            MsgBox("finally")

        ElseIf value = B Then
            MsgBox("finally")

        ElseIf value = outline Then
            MsgBox("finally")

        ElseIf value = outlineColor Then
            MsgBox("finally")

错误是：Terraria Smart Cursor.exe中发生类型为“System.IndexOutOfRangeException”的未处理异常

附加信息：索引超出了数组的边界

您正在访问一个容器，该容器在位置0处工作，然后在位置1处不工作。屏幕截图中显示的异常表示这是一个超出范围的问题。因此，您的容器没有预期的大：它只有1个元素。

您正在通过Dim ary以String=line的形式填充ary。拆分：。您正在阅读C:\Users\Matthew\Documents\My Games\Terraria\config.json中的每一行

该文件的一行不包含：。因此，拆分只创建一个元素数组。当你打电话时：

Dim value1 As String = ary(1).Trim()

由于元素1不存在，您将获得ArgumentOutOfRangeException

---

解决方案是测试数组长度，让代码以优雅的方式处理不带：的行。

请以代码的形式发布一个简短但完整的示例。这里没有理由使用图像。很容易解释：你将代码粘贴到你的问题中，说你正在获取ArgumentOutOfRangeException，并说它发生在哪一行。这仍然不是一个简短但完整的示例。它既不短也不完整，也没有告诉我们您要拆分哪个值。还不清楚为什么在没有C的情况下用C标记此变量。请阅读您的ary变量仅包含元素0，而不包含元素1。因此，您粘贴的代码不是问题的原因；它发生得更早，假设您甚至需要value1，不管它是什么；请在你的代码中使用有意义的变量名，因为到目前为止，你不会在你发布的内容中使用它。现在我所有的代码都有了…如果value=R，那么MsgBoxary1.TrimChr44 end如果value不等于R的情况如何？R、G、B都是我关心的。。其他什么都不重要。。此外，除变量外，所有3个变量的代码都是相同的。后一个代码有效，因为只有当value=R时才测试ary1。前一个代码失败，因为即使在value不等于R的情况下也可以访问ary1。因此，如果我想在不删除这些括号的情况下修复此问题。。我该怎么做？编辑：Nvm我知道如何。。只需在Try函数中声明它

Dim value1 As String = ary(1).Trim()
