check if object is null

[Giulio Mastrosanti]

How can I check if a declared object in not initialized yet with a new
command?
is catching the exception while accessing it the only way?

thanx

Giulio,

How can I check if a declared object in not initialized yet with a new
command?

if ( obj == null ) ...

is catching the exception while accessing it the only way?

No, it's probably the worst way.

You can also check by using the == operator.

For example:

using System;

class nullcheck
{
private static Foo f;

[STAThread]
static void Main(string[] args)
{
// f = new Foo();
if (f == null)
Console.WriteLine("Foo is not initialized!!!");
else
Console.WriteLine("Foo is initialized.");
return;
}
}

class Foo
{
public int x = -1;
public Foo()
{
x = 5;
}
}
