将Linq转换为SQL的便捷方法

以下代码可以将Linq快捷的转换为SQL，以供我们分析程序。，以下是代码：

   1:  using (NorthwindEntities context = new NorthwindEntities())

   2:  {

   3:      string s = string.Empty;

4:

   5:      var query = context.Region.Where(o=>o.RegionID<100).OrderBy(p=>p.RegionID);

   6:      s = (query as ObjectQuery).ToTraceString();

   7:      Response.Write(s);

8:

   9:      Response.Write("<hr/>");

10:

  11:      var query1 = from p in context.Region

  12:                   where p.RegionID > 0

  13:                   select p;

  14:      s = (query1 as ObjectQuery).ToTraceString();

  15:      Response.Write(s);

  16:  }
