ByRef or ByVal? [Resolved]

Last question for today.

VB Code:

static void RunApp(object state) 
        {
            Application.Run((Form)state);
        }

I am currently converting it to VB.NET, I'd like to know whether "state" is being passed ByRef or ByVal. Does C# have the concept of ByRef/ByVal?

I am not quite sure bout that but if I recall correctly,......

if you pass an object it will always be passed by refrence.
But yes you can also specify that using keywords ref (out) or val.

heres an example:

Code:

---

                private void button2_Click(object sender, System.EventArgs e)
                {
                        System.Xml.XmlDocument myDoc  = new System.Xml.XmlDocument();
                        testFunction(myDoc);
                        textBox2.Text = myDoc.SelectSingleNode("//test").InnerText;
                       
                }
                private void testFunction(System.Xml.XmlDocument myDoc)
                {
                        myDoc.LoadXml("<test>value</test>");
                }

Please do corrcet me if I am wrong!

Reference types (Forms, other complex objects) will always be ByRef. Value types (primatives, structs) will always be ByVal unless the ref modifier is used.

OK, so what I understand is that it's the same deal as in VB.NET, except it's taboo to mention it in C#.

Yup

Wont arrays also be essentially byref as well?

That's what I assumed too.
