各位师傅请看下面代码:"找不到类型或命名空间名称“SqlConnetion”(是否缺少 using 指令或程序集引用?)",请指点指点.

        DataSet ds = new DataSet();

        da.Fill(ds);

        DataGrid1.DataSource = ds;

    } --------------------编程问答-------------------- 楼主打错字了，
建议在输入时使用命名空间+"."+类名方式
如System.Data.SqlClient.Sqlconnection ...
这样就不会出现输错类名的情况了，因为IDE有提示功能，并不会让输入效率降低多少（不过要是能输对了也无所谓了） --------------------编程问答-------------------- 楼主不认真啊，没有使用智能提示。全自己敲啊，还是蛮牛的！ --------------------编程问答--------------------
