Value of type 'String' cannot be converted to '1-dimensional array of String'?

Expand Post »

TEXT file csvSTOCKS.TXT contains the following:
Stock 1,200,300,200,200
Stock 2,200,300,200,200
Stock 3,200,300,200,200
Stock 4,200,300,200,200
Stock 5,200,300,200,200

I'm attempting to read each line in the text file and put it in the array of strings lines()

vb Syntax (Toggle Plain Text)
        Dim sr As StreamReader = New StreamReader("csvSTOCKS.TXT")
 
        Dim lines() As String
 
        Do While (sr.Peek <> -1)
            lines = sr.ReadLine
        Loop
 
        lstOutput.Items.Add(lines(0))
        Dim sr As StreamReader = New StreamReader("csvSTOCKS.TXT")

        Dim lines() As String

        Do While (sr.Peek <> -1)
            lines = sr.ReadLine
        Loop

        lstOutput.Items.Add(lines(0))

BUT, I get the following error when I try to assign lines = sr.ReadLine
ERROR:

VB.NET Syntax (Toggle Plain Text)
Error	1	Value of type 'String' cannot be converted to '1-dimensional array of String'.
Error	1	Value of type 'String' cannot be converted to '1-dimensional array of String'.

If this cannot be done, is there a way to do that ?

Re: Value of type 'String' cannot be converted to '1-dimensional array of String'?

You have to redimension your lines array:

VB.NET Syntax (Toggle Plain Text)
        Dim sr As StreamReader = New StreamReader("csvSTOCKS.TXT")
        Dim lines() As String
        Dim index As Integer = 0
 
        Do While (sr.Peek <> -1)
            ReDim Preserve lines(index)
            lines(index) = sr.ReadLine
            index += 1
        Loop
        Dim sr As StreamReader = New StreamReader("csvSTOCKS.TXT")
        Dim lines() As String
        Dim index As Integer = 0

        Do While (sr.Peek <> -1)
            ReDim Preserve lines(index)
            lines(index) = sr.ReadLine
            index += 1
        Loop

or use an array list:

VB.NET Syntax (Toggle Plain Text)
        Dim sr As StreamReader = New StreamReader("csvSTOCKS.TXT")
        Dim lines As ArrayList = Nothing
 
        Do While (sr.Peek <> -1)
            lines.Add(sr.ReadLine)
        Loop
        Dim sr As StreamReader = New StreamReader("csvSTOCKS.TXT")
        Dim lines As ArrayList = Nothing

        Do While (sr.Peek <> -1)
            lines.Add(sr.ReadLine)
        Loop
