Hi!
There is a problem in Mono 1.0 when replacing in a string or =
stringbuilder object.
Try
'Dim myBuffer As New System.Text.StringBuilder
Dim mybuffer As String
Dim myReader As New System.IO.StreamReader(WindowsFile, =
System.Text.Encoding.Default, False)
Dim myWriter As New System.IO.StreamWriter(UnixFile, False, =
System.Text.Encoding.Default)
Console.WriteLine("Reading file...")
'myBuffer.Append(myReader.ReadToEnd)
mybuffer =3D myReader.ReadToEnd()
myReader.Close()
Console.WriteLine("Converting data...")
myBuffer.Replace(vbCrLf, vbLf)
Console.WriteLine("Writing file...")
myWriter.Write(myBuffer.ToString)
myWriter.Close()
Console.WriteLine("File successfully converted")
Catch ex As Exception
System.Console.WriteLine(ex.ToString)
System.Console.ReadLine()
End Try
The myBuffer variable contains a string of 7 MB. For small strings, it =
seems to work. But with larger ones as my 7 MB string, the line
myBuffer.Replace(vbCrLf, vbLf)
runs more than half an hour before finishing.
Can somebody please fix this asap? Thanks!!!
Regards
Jochen
