小编Tuy*_*yen的帖子

以下两种情况有什么区别:

class Data
{
    PersonDataContext persons = new PersonDataContext();
    public Data() {}
}

与

class Data
{
    PersonDataContext persons;
    public Data() 
    {
        persons = new PersonDataContext();
    }
}

我在asp.net中有同样的问题:

public partial class Data : System.Web.UI.Page
{
    PersonDataContext persons = new PersonDataContext();
    protected void Page_Load(object sender, EventArgs e)
    {
    }
}

与

public partial class Data : System.Web.UI.Page
{
    PersonDataContext persons;
    protected void Page_Load(object sender, EventArgs e)
    {
        persons = new PersonDataContext();
    }
}
