//定义s 等于空
string s = "";
//获取值
string code = context.Request["id"].ToString();
//删除
var query = _Context.Car.Where(p => p.Code == code);
if (query.Count() > 0)
{
//找到第一个
Car data = query.First();
//告诉上下文删除
_Context.Car.DeleteOnSubmit(data);
//返回到数据库
_Context.SubmitChanges();
//如果找到了 把s 设为true
s = "true";
