I try to convert a VB.net class into a C# class but i have an error !

The SetToDefault function return me an error !

Where is my error please !

Thanks

What's the actual error you are getting? I thought you could only set static variables inside a static method, but I might be wrong...

In french the error is 'Identificateur attendu'

I have found my issue with the msdn help !!!

the good translated class is :

I have always an issue with the deserialer function!
I have tried:

Code:

---

    public static void DeseralizeFromXML(cMySettings Settings)
    {
        FileStream fs = null;
        // do i have settings?
        if (File.Exists(XMLFilename) == true)
        {
            try
            {
                fs = new FileStream(XMLFilename, FileMode.Open, FileAccess.Read);
                XmlSerializer xmlSerializer = new XmlSerializer(typeof(cMySettings));
                Settings = (cMySettings)xmlSerializer.Deserialize(fs);
            }
            catch
            {
                //load error of some sort, or OBJECT deserialize error
                //do we tell anyone?
                return;
            }
            finally
            {
                if ((fs != null))
                    fs.Close();
                fs = null;
            }
        }

    }

---

and also:

Code:

---

    public static void DeseralizeFromXML(cMySettings i)
    {
        FileStream fs = null;
        // do i have settings?
        if (File.Exists(XMLFilename) == true)
        {
            try
            {
                fs = new FileStream(XMLFilename, FileMode.Open, FileAccess.Read);
                XmlSerializer xmlSerializer = new XmlSerializer(typeof(cMySettings));
                XmlReader reader = XmlReader.Create(fs);
                //cMySettings i;
                i = (cMySettings)xmlSerializer.Deserialize(reader);
            }
            catch
            {
                //load error of some sort, or OBJECT deserialize error
                //do we tell anyone?
                return;
            }
            finally
            {
                if ((fs != null))
                    fs.Close();
                fs = null;
            }
        }

    }

But when i try to read my variable , by example PluginSettings.COMPort , the variable is empty !

Ok, If i convert the VB.NET code that follow , i obtain an error for the red line !!!

Code:

---

    Public Shared Sub DeseralizeFromXML(ByRef Settings As cMySettings)
        Dim fs As FileStream = Nothing
        ' do i have settings?
        If File.Exists(XMLFilename) = True Then
            Try
                fs = New FileStream(XMLFilename, FileMode.Open, FileAccess.Read)
                Dim xmlSerializer As New XmlSerializer(GetType(cMySettings))
                Settings = xmlSerializer.Deserialize(fs)
            Catch
                'load error of some sort, or OBJECT deserialize error
                'do we tell anyone?
                Exit Sub
            Finally
                If Not fs Is Nothing Then fs.Close()
                fs = Nothing
            End Try
        End If

    End Sub

---

In c# i obtain these lines:

Code:

---

    public static void DeseralizeFromXML(cMySettings Settings)
    {
        FileStream fs = null;
        // do i have settings?
        if (File.Exists(XMLFilename) == true)
        {
            try
            {
                fs = new FileStream(XMLFilename, FileMode.Open, FileAccess.Read);
                XmlSerializer xmlSerializer = new XmlSerializer(typeof(cMySettings));
                Settings = xmlSerializer.Deserialize(fs);
            }
            catch
            {
                //load error of some sort, or OBJECT deserialize error
                //do we tell anyone?
                return;
            }
            finally
            {
                if ((fs != null))
                    fs.Close();
                fs = null;
            }
        }

    }

---

the error is 'can't convert the object in cMySettings

Thanks for your help !!!

not seeing this completely

but in c# classes that you want to serialize should have a Serializable attribute

[Serializable]

then serial/deserial is easy!
that code looks like my code :)

anyway, there is tons of C# examples outside of this forum...

attached is example

hey I got some C# books, can you read English well enough?, id give you a book for free, just pay shipping
good books.... ill get you more info... and titles
(yea, real books, made of paper!)

Why not, Thanks !

micthjs, you are the best :-)
Into my Deserialize command , i have just added a 'ref' i don't know why and all is running well know so my code is :

Code:

---

    public static void DeseralizeFromXML(ref cMySettings Settings)
    {
        FileStream fs = null;
        // do i have settings?
        if (File.Exists(XMLFilename) == true)
        {
            try
            {
                fs = new FileStream(XMLFilename, FileMode.Open, FileAccess.Read);
                XmlSerializer xmlSerializer = new XmlSerializer(typeof(cMySettings));
                //cMySettings i;
                Settings = (cMySettings)xmlSerializer.Deserialize(fs);
            }
            catch
            {
                //load error of some sort, or OBJECT deserialize error
                //do we tell anyone?
                return;
            }
            finally
            {
                if ((fs != null))
                    fs.Close();
                fs = null;
            }
        }

    }

---

And i initialise the xml file like that:

Code:

---

  DPath = pluginDataPath;

            //Settings with Xml file
            PluginSettings = new cMySettings(DPath + "iCarDuino");

            // read in defaults
            cMySettings.DeseralizeFromXML(ref PluginSettings);
            // copy to temp
            TempPluginSettings = new cMySettings(PluginSettings);
