EF增删查改加执行存储过程和sql语句，多种方法汇总

ActionUrl c = new ActionUrl() { ActionName="test", RequestUrl="/123/123", SubTime=DateTime.Now };
//增
using (EntityContext db = new EntityContext())
{

/*方法1*/
db.ActionUrls.Add(c);
db.SaveChanges();
/*方法2*/
db.Set<ActionUrl>().Attach(c);
db.Entry<ActionUrl>(c).State = EntityState.Added;
db.SaveChanges();
//return c;
/*方法3*/
//EF4.0的写法
//db.CreateObjectSet<T>().AddObject(entity);

}
//查
using (EntityContext db = new EntityContext())
{
c = db.ActionUrls.Where(t => t.ActionName == "test").FirstOrDefault();
}
//改
using (EntityContext db = new EntityContext())
{
/*方法1*/
c.ActionName = "test001";
db.ActionUrls.Attach(c);
db.Entry<ActionUrl>(c).State = EntityState.Modified;
db.SaveChanges();
/*方法2*/
c.ActionName = "test002";
db.SaveChanges();
//return db.SaveChanges() > 0;
/*方法3*/
//EF4.0的写法
//db.CreateObjectSet<T>().Addach(entity);
//db.ObjectStateManager.ChangeObjectState(entity, EntityState.Modified);
}
//删
using (EntityContext db = new EntityContext())
{
/*方法1*/
//此处删除的对象不能是自己定义出来的对象，只能是数据库查询出来的对象
c = db.ActionUrls.Where(t => t.ActionName == "test").FirstOrDefault();
db.ActionUrls.Remove(c);
db.SaveChanges();
/*方法2*/
//c = db.ActionUrls.Where(t => t.ActionName == "test").FirstOrDefault();
db.Set<ActionUrl>().Attach(c);
db.Entry<ActionUrl>(c).State = EntityState.Deleted;
db.SaveChanges();
//return db.SaveChanges() > 0;
/*方法3*/
//EF4.0的写法
//db.CreateObjectSet<T>().Addach(entity);
//db.ObjectStateManager.ChangeObjectState(entity, EntityState.Deleted);
}

//存储过程和sql语句
EntityContext dbsql = new EntityContext();
SqlParameter[] parameters = new SqlParameter[]{
new SqlParameter("@name",SqlDbType.NVarChar)
};
parameters[0].Value = "test";

//执行strSql/procSql
//返回受影响的行数
int i = dbsql.Database.ExecuteSqlCommand("exec getActionUrlId @name", parameters);

List<ActionUrl> dd01 = dbsql.Database.SqlQuery(typeof(ActionUrl), "exec getActionUrlId @name", parameters).Cast<ActionUrl>().ToList();
//执行strSql/procSql
//返回数据的集合
List<ActionUrl> dd02 = dbsql.Database.SqlQuery<ActionUrl>("exec getActionUrlId @name", parameters).ToList();//返回查询到的实体集合
