Hello friends i recently converted my VB6 project to VB.net.
I am getting the following errors in the converted VB.net project:

'UPGRADE_ISSUE: Constant vbUnicode was not upgraded. Click for more: 'ms-help://MS.VSCC.v90/dv_commoner/local/redirect.htm?keyword="55B59875-9A95-4B71-9D6A-7C294BF7139D"'
'UPGRADE_ISSUE: InputB function is not supported. Click for more: 'ms-help://MS.VSCC.v90/dv_commoner/local/redirect.htm?keyword="367764E5-F3F8-4E43-AC3E-7FE0B5E074E2"'

Following is the code snippet which gives the error:

VB
 Dim EncryptedFilePath As String

 Dim EncryptedFileNumber As Integer

 Dim EncryptedText As String
EncryptedText = StrConv(InputB(LOF(EncryptedFileNumber), EncryptedFileNumber), vbUnicode)


Please correct this code snippet.

What I have tried:

i tried this but it is returning some other result. I am new to VB6 and VB.net, please help.

VB
' The input String.
Dim value As String = LOF(EncryptedFileNumber)

' Convert String to Byte array.
Dim array() As Byte = System.Text.Encoding.ASCII.GetBytes(value)

EncryptedText = System.Text.Encoding.Default.GetString(array)

That code is reading the contents of a file which you have previously opened. You will presumably have a previous line that looks something like:
VB.NET
Open EncryptedFilePath For Input As #EncryptedFileNumber

File IO is much easier in .NET - the System.IO namespace[^] gives you all the tools you need.

Replace the Open / InputB / Close lines with:
VB.NET
Dim EncryptedText As String = System.IO.File.ReadAllText(EncryptedFilePath)
