Hi,
I'm not having a lot of luck googling for this one, I want to be able to
store a custom class in the user settings (DotNet2.0, win app). I don't
wish to create public get / set properities for all the things I want to
persist just for storing in the user settings file (because that would allow
other apps to access / change data they shouldn't be able to).
I understand how to browse to the object in VS2005 to add an entry to the
settings file., but I'm not sure what I need to do to my class to get it to
work. Using a very basic example below, is there an interface I should
inherit from? I'm guessing there must be an interface that defines at least
two methods, one that returns an xml string of the parameters to persist and
another that takes that xml string and allows the class to initalise itself
internally. (Note I really don't want to add Get/Set for val1 and val2 just
to get default persistance of all public properties).
Thanks in Advance,
- Paul
public ClassA
{
private int val1;
private string val2;
ClassA( val1, val2)
{
this.val1 = val1;
this.val2 = val2;
}
public bool Valid()
{
return ((val1 10) && !string.IsNullO rEmpty(val2));
}
public string Text()
{
return (val1.ToString( ) + ' ' + val2);
}
} 2 8345
The class must be serializable as XML. In order for it to be serializable as
XML, keep in mind that XML Serialization does not serialize classes without
parameterless constructors, so you need to add one to your class. In
addition, private fields, methods, and read-only (get only) properties are
not serialized. See http://msdn2.microsoft.com/en-us/library/182eeyhh.aspx
for more information.

Thanks for your answer - when I couldn't find anything online I had wondered
if this was using the Xml Serialisation object as I've seen it before
posting objects on a message queue. I had hoped that you would be able to
either override the Xml Serialisation object for saving particular classes -
or have the object inherit from a common interface and provide specialised
functionality that the Xml Serialisation provides.
As I don't want to provide a default constructor and expose the private
attributes / change the read only properties; I guess the best solution
would be to create a thin helper class, that just contains the data I wish
to be saved (and no functionality) and then pass this into / from my class
before serialisation. That way I can keep the encapsulation in my class /
application and also use the functionality provided by Xml Serialisation.

I have an application we are building that will be used by a number of
different users on shared PCs. I want to be able to store a number of user
settings in a location that is unique for each user, so that one user's
settings do not affect another. Is there a "standard" location to store
these files? How about a "standard" location to store a file of default
settings if the user hasn't run the application yet?

I am trying to use a custom type inside settings.settings. When I create my
