C#.net 2008

I’m working on a class file with a few hundred properties across about 8 serialized categories.
At the moment it will look like this:

[CategoryAttribute("Group1")]
public string property
[CategoryAttribute("Group1")]
public string property
[CategoryAttribute("Group1")]
public string property
[CategoryAttribute("Group1")]
public string property

[CategoryAttribute("Group2")]
public string property
[CategoryAttribute("Group2")]
public string property
[CategoryAttribute("Group2")]
public string property
[CategoryAttribute("Group2")]
public string property

I’ve done research in past times and haven’t found any leads to a solution so this time I’m asking if anyone has a solution to get something less messy?
Such as:

[CategoryAttribute("Group1")]
{
public string property;
public string property;
public string property;
public string property;
public string property;
public string property;
public string property;
}
[CategoryAttribute("Group2")]
{
public string property;
public string property;
public string property;
public string property;
public string property;
public string property;
public string property;
}

    While all the other answers are completely correct, i could propose you another idea.

    You could try to use T4 templates to generate such file.
    Please see my example at GitHub

    Basically I created a template /EntitiesWithALotOfProperties/FirstClass.generated.tt, which reads a file with same name, but with replaced “.generated.tt” to “.template.cs” and processes the latter according to your logic.

    What is important to note: the FirstClass.template.cs should have set the build action to ‘None‘. The idea was: *.cs files can be easily edited with ReSharper (basically have IntelliSense), but at the same time, it doesn’t declare duplicate members.

    Here are some screenshots:
