我一直有問題試圖找出一種方法來搜索數組,只需從包含信息的.txt文件中獲取代碼行。我希望能夠擺脫我將意外放入輸入文件的空返回空格(空數組元素)。刪除源自.txt文件輸入的空數組元素
我有一個數組,它讀取輸入文件中的所有行。我添加了一個樣本輸入,我將其添加到樣本輸入文件中。
Line1
Line2
Line3
Line4
Line5
我有另一個數組,這將是所有的空間已被佔到後的finalArray,應該只是一個沒有空行返回的數組。我似乎無法解釋空迴歸元素。
我剛剛得到相同的輸出。我希望它讀作;
Line1
Line2
Line3
Line4
Line5
這將使隨機化數組的第二部分更容易,如果我能找到解決方案來解決空數組元素。我已經添加了以下代碼以供參考。
Imports System.IO
Module ListRandomizer
Sub populateArray(ByVal inputArray() As String, ByRef startArray() As String)
Dim pos As Integer = 0
For Each element As String in inputArray
If element <> "" Then
startArray(pos) = element
End If
pos += 1
Next
End Sub
Sub Main()
Dim myWriter As StreamWriter
Dim inputArray() As String
inputArray = File.ReadAllLines("sampleInput.txt")
myWriter = New StreamWriter("sampleOutput.txt")
Dim currLine As Integer = 1
Dim size As Integer = 0
For Each element As String in inputArray
Console.WriteLine("LINE {0}, " & element, currLine)
currLine += 1
If element <> "" Then
size += 1
End If
Next
Console.Writeline(size)
Dim startArray(size) As String
populateArray(inputArray, startArray)
For Each fern As String in startArray
Console.WriteLine("LINE {0}, " & fern, currLine)
currLine += 1
Next
myWriter.Close()
System.Console.ReadLine()
End Sub
End Module
