求助，关于sql带入参数的写法问题。

[han3210165]

string sql = "SELECT ID,n_title,shijian FROM [news_contents] WHERE typeid =" + type ;
我想在这一句里面加一个关于ID的降序排列，麻烦各位朋友看看怎么写，谢谢。

[白云任去留]

string sql = "SELECT ID,n_title,shijian FROM [news_contents] WHERE typeid =" + type + " order by Id desc" ;

[Mirror然]

string sql = "SELECT ID,n_title,shijian FROM [news_contents] WHERE typeid =" + type + " order by id desc";
