Hi, a little question about access properties

[perencia]

Can someone explain me what's wrong with this code ?

public class a {
private string patr = @"\w@\w\.\w";
private Regex regexp = new Regex(patr);
....

I know if i change the accesor modifier of patr from private to static it runs, but i'd like to know why ..

Thanks!.

As you can see the compiler shows:
"A field initializer cannot reference the nonstatic field, method, or property ".
The solution is, for example , to initialize the field in the class constructor:

public class a {
private string patr = @"\w@\w\.\w";
private Regex regexp;
public a()
{
 regexp = new Regex(patr);
}
....
}

The string patr = @"\w@\w\.\w";
initialization is working because the right member is a built-in type.
