帮助：索引在vb 2010中超出了数组的范围 [英] HELP: Index was outside the bounds of the array in vb 2010
问题描述
大家好，我有点卡在这里因为我不是很好的编程而且还在学习:)
我遇到了错误索引超出界限的数组。我放置了msgboxes，以便我真的知道它是如何流动的（我没有使用调试工具，因为我不想要它。:)）
无论如何我到目前为止所做的解决方案是：
1.我使用
Hello guys, im a bit stuck here as im not that good in programming and still learning :)
im stuck with an error "Index was outside the bounds of the array". i placed msgboxes so that i could really know how it is flowing, (i did'nt use the debug tool because i dont want it. :) )
anyhow the solutions i have made so far are:
1. i used
Option Explicit on =没有用。
2.试图减少无限（ arrayTextFile）
= didnt worked.
2. tried to lessen the ubound(arrayTextFile)
For i = 1 To UBound(ArrayTextFile) - 2它再次工作
3.我用过这种检查，我真的不知道它做了什么。但它让我失望:(
it ddnt work again
3. i used this kind of checking, i really dont know what it did. but it failed me :(
Dim placename As String
If ListView1.Items.Count > 0 Then
placename = ListView1.Items.Count = 0
Else
placename = String.Empty
End If
i知道我错过了一些我无法通过代码看到的东西，
所以任何人都可以帮助我。谢谢你们。
这里是函数的代码。
我通过MsgBox后（inside with - & ListView1.Items.Count）我指示了adady到catch并发布了消息索引超出阵列范围
i know i am missing something i just cant see through codes,
so can anybody please help me. thank you guys.
here's the code for the function.
after i pass MsgBox("inside with - " & ListView1.Items.Count) Im directed aleady to the catch and posted with the message "Index was outside the bounds of the array"
Try
Dim ArrayTextFile() As String
Dim lineOfText As String
Dim i As Integer
lineOfText = rcvdata.ToString
ArrayTextFile = Split(lineOfText, "+CMGL", , CompareMethod.Text)
MsgBox("did i pass here?" & i)
MsgBox(UBound(ArrayTextFile))
For i = 1 To UBound(ArrayTextFile)
Dim input As String = ArrayTextFile(i)
Dim result() As String
Dim pattern As String = "(:)|(,"")|("","")"
MsgBox("did i pass here? -pattern")
result = Regex.Split(input, pattern)
Dim lvi As New ListViewItem
Dim concat() As String
MsgBox("did i pass here? -lvi and concat")
With (ListView1.Items.Add("null"))
MsgBox("inside with - " & ListView1.Items.Count)
'for item 1
.SubItems.AddRange(New String() {result(2)})
MsgBox("did i pass here? result 2")
'for item 2
.SubItems.AddRange(New String() {result(4)})
MsgBox("did i pass here? -result 4")
'extract numbers
Dim myString, position As String
myString = result(6)
position = myString.Length - 2
myString = myString.Remove(position, 2)
.SubItems.Add(myString)
MsgBox("did i pass here? -result5")
'for date/time
concat = New String() {result(8) & result(9) & result(10) & result(11) & result(12).Substring(0, 2)}
.SubItems.AddRange(concat)
'message extracted
Dim lineOfTexts As String
Dim arrayTextFiles() As String
lineOfTexts = ArrayTextFile(i)
arrayTextFiles = Split(lineOfTexts, "+32", , CompareMethod.Text)
.SubItems.Add(arrayTextFiles(i))
End With
MsgBox("did i pass here? going to the top to loop again")
Next
MsgBox("loop finish")
Catch ex As Exception
MsgBox("what is wrong?" & ex.Message)
End Try
End Sub
推荐答案
首先 - 使用调试器如果你想被认真对待。你不仅可以很快确定错误发生的位置，还可以轻松检查局部变量，以帮助确定错误。
显然，数组结果只有2个元素，并且您尝试使用result（2）<访问第三个元素/ code>
记住数组等往往是从零开始的，即result（0）将是第一个不是结果的元素（1）
Firstly - use the debugger if you want to be taken seriously. Not only can you determine exactly where the error occurred very quickly you can also easily examine the local variables to help determine what is wrong.
Clearly array result only has 2 elements and you are trying to access a third withresult(2)
Remember arrays etc tend to be zero-based i.e. result(0) would be the first element not result(1)
