这个小程序怎么跑起来啊,第一天搞.net,求指导

Answer 1

就是连接数据库,读几个值,读到界面里面就ok
用wpf

Answer 2

你这是wpf 貌似发错地方了 童鞋

Answer 3

WPF也只能发C#区了，要么就发SilverLight区。其实应该给WPF专门建一个讨论区的。。

Answer 4

首先保证连接字符串对了
你直接看 sda.Fill(dt);dt.Rows.Count得值就行了，Count>0取到了值。反之则反。

Answer 5

易,wpf不是c#?
我没找着专区

Answer 6

Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that does not return any key column information.
 sda = new SqlDataAdapter("select  Number,name,grade,sex from students;", conn);上面这句写的不对么..???

Answer 7

connbuilder.InitialCatalog
怎么写?

Answer 8

就是这句的问题
sda.UpdateCommand = commbuilder.GetUpdateCommand();
