write to textfile samt gemme struct

For at gemme objekter skal du benytte dig af "Object Serialization"

hvis du bare vil gemme tekst i en fil skal du bruge funktionen: StreamWriter

Dim SW As IO.StreamWriter = New IO.StreamWriter("c:\enfil.txt")
SW.Write("Noget tekst")
SW.Close()

For at læse tekst fra fil skal du bruge "StreamReader"

Måske er dette link bedre: http://abstractvb.com/code.asp?F=159&P=1&A=1018

Jeg vil foreslå XmlSerializer.

Det minder utroligt meget om SoapSerializer eksemplet i ovenstående
link, men du har næppe noget at bruge det ekstra SOAP stuff til.

Simpelt kode eksempel:

Imports System
Imports System.IO
Imports System.Xml.Serialization

Public Structure Test
    Public a As Integer
    Public b As Double
    Public c As String
End Structure

Class MainClass
    Public Shared Sub Main(ByVal args As String())
        Dim tst As Test
        tst.a = 123
        tst.b = 123.456
        tst.c = "ABC"
        Dim ser As XmlSerializer = New XmlSerializer(GetType(Test))
        Dim sw As StreamWriter = New StreamWriter("C:\test.xml")
        ser.Serialize(sw, tst)
        sw.Close
        Dim sr As StreamReader = New StreamReader("C:\test.xml")
        Dim tst2 As Test = CType(ser.Deserialize(sr), Test)
        sr.Close
        Console.WriteLine(tst2.a & " " & tst2.b & " " & tst2.c)
    End Sub
End Class

OK ?
