WPF数据修改demo

今天晚上研究了下wpf，现在把代码贴出来供大家学习参考

sql语句：

create table userinfos

(

 ContactID  int primary key identity(1,1),

FirstName varchar(100),

LastName varchar(100),

EmailAddress varchar(100)

)

go

insert into  userinfos values('wanglei','aa','72121222@qq.com');

insert into  userinfos values('qss','bb','23432354@qq.com');

insert into  userinfos values('gdgg','cc','rgter@qq.com');

insert into  userinfos values('cvvd','dd','5446567576@qq.com');

select ContactID,FirstName,LastName,EmailAddress from userinfos where ContactID<=100
