I'm trying to run this code in Option Strict mode off and every things is okay:
Public Function ReadALine(ByVal File_Path As String, ByVal TotalLine As Integer, ByVal Line2Read As Integer) As String
try
Dim Buffer as Array
Dim Line As String
If TotalLine <= Line2Read Then
Return "No Such Line"
End If
Buffer = File.ReadAllLines(File_Path)
Line = Buffer(Line2Read)
Return Line
Catch ex As Exception
End Try
End Function
But when I turned it on, then vb.net say this error to me :
Option Strict On disallows late binding.
In this line and under buffer value I see the red line for error:
Line = Buffer(Line2Read)
I tried to convert with ctype, to string, or integer, but the problem is not solved yet!
My friend helped to me to fix that issue. Try:
Dim readAllLines = File.ReadAllLines(filePath)
Dim Buffer(readAllLines.Length) As String
Dim Line As String
If TotalLine <= Line2Read Then
Return "No Such Line"
End If
Buffer = readAllLines
Line = Buffer(Line2Read)
Return Line
