我们的想法是创建一个暴露上下文但在Web应用程序中处理它的存储的类.

目前这就是我所拥有的:

public class EntityContext
{

    private static String MAIN_CONTEXT_KEY = "MainContext";
    private static TISQLEntities _context;

    public static void RemoveContext()
    {
        if (
            HttpContext.Current != null 
            && 
            HttpContext.Current.Items[MAIN_CONTEXT_KEY] != null
           )
        {
            ((TISQLEntities)HttpContext.Current.Items[MAIN_CONTEXT_KEY]).Dispose();
            HttpContext.Current.Items[MAIN_CONTEXT_KEY] = null;

        if (_context != null)
        {
            _context.Dispose();
            _context = null;
        }
    }

    public static TISQLEntities Context
    {
        get

            if (HttpContext.Current == null)
            {
                if (_context == null)
                {
                    _context = new TISQLEntities();
                }

                return _context;
            }

            if (HttpContext.Current.Items[MAIN_CONTEXT_KEY] == null)
            {
                HttpContext.Current.Items[MAIN_CONTEXT_KEY] = …
