Question

I have got several classes looking like the one below, and I need to do some checks in the get method and custom set methods. Adding the code in each get and set method makes everything look really messed up.

Is there a way I can override the get and set methods for all properties in an entire class?

public class Test
{
    private DataRow _dr;
    public Test()
    {
        _dr = GetData();
    }

    public string Name
    {
        get { return _dr[MethodBase.GetCurrentMethod().Name.Substring(4)].ToString(); }
        set
        {
            VerifyAccess(MethodBase.GetCurrentMethod().Name.Substring(4), this.GetType().Name);
            _dr[MethodBase.GetCurrentMethod().Name.Substring(4)] = value;
        }
    }

    public string Description
    {
        get { return _dr[MethodBase.GetCurrentMethod().Name.Substring(4)].ToString(); }
        set
        {
            VerifyAccess(MethodBase.GetCurrentMethod().Name.Substring(4), this.GetType().Name);
            _dr[MethodBase.GetCurrentMethod().Name.Substring(4)] = value;
        }
    }

    public string DescriptionUrl
    {
        get { return _dr[MethodBase.GetCurrentMethod().Name.Substring(4)].ToString(); }
        set
        {
            VerifyAccess(MethodBase.GetCurrentMethod().Name.Substring(4), this.GetType().Name);
            _dr[MethodBase.GetCurrentMethod().Name.Substring(4)]= value;
        }
    }


    private void VerifyAccess(string propertyname, string classname)
    {
        //some code to verify that the current user has access to update the property
        //Throw exception
    }

    private DataRow GetData()
    {
        //Some code to pull the data from the database
    }
}

I think what you need is a Proxy on your class, read about Proxy Pattern and Dynamic Proxies
