VB - Writing to a file with StreamWriter


I'm trying to write to a file using the StreamWriter.

Dim write as IO.StreamWriter
write = new io.streamwriter(file)
write.write(txtEncryption.text)
write.close

I stopped the code in debug mode and i saw it crashes and goes straight to the exception when reaches line 2.

It is because i just made the file and it's still in use ? How can i avoid that ?


Solution

  • Dim write As  IO.StreamWriter 
    Try 
      write=New IO.StreamWriter(file)  
      write.write(txtEncryption.text)
    
    Catch ex As Exception
      'Prompt error
      Console.WriteLine("Error {0}",ex.Message)
    
    Finally 
        If write IsNot Nothing Then
            write.Close() 
        End If
    End Try 
    

    Assumption (if file was not opened anywhere else) : You open already opened one.Make sure that all your opened streams closed properly. You can use this syntax too

    Using writer As StreamWriter = New StreamWriter(file)
            writer.Write("....")
               //and so on
    End Using
