Short Question on Performance

[Christian Döring]

Hi,

Is it ok to create a new instance of a class on every Page_Load?

Given the following code behind a form:

protected void Page_Load(object sender, EventArgs e)
{
myclass= new MyClass(myControl);
}

protected void btnStart_Click(object sender, EventArgs e)
{
myclass.loadXYZ(0);
}

And the snippet from MyClass

public MyClass (MyControl c)
{
this.mycontrol = c;
}
public loadXYZ(int x)
{
...
c.text="abc"
}

So I need a reference to myControl which is on the form. My first approach
was to just pass it by the constructor of MyClass on the Page_Load event. Is
this just fine or do I loose performance?

It should be ok.

Object creation is only heavy if you are dong heavy stuff in the
contstructor...which you don't seem to be doing...ur just assigning a
reference..

I might also mention that *every* object in the Page is re-created with each
Page_Load, including the Page class itself.

No heavy stuff in there...

Thank you both for your help!
