asp.net登录代码

aspx文件

在Web Form里:

加入两个Label控件,Text属性分别为“登录名”和“密码”;

加入两个TextBox控件,ID属性分别为“Userid”和“Pwd”,Text属性均为空;

加入两个RequiredFieldValidato控件,ID属性分别为“rfvUserid”和“rfvPwd”,Text属性分别为“请输入登录名!”和“请输入登录密码!”,ControlToValidate属性分别为"Userid"和"Pwd";

加入一个Button控件,ID属性为“LogButton”,Text属性别为“登录”;

最后加入一个Label控件,ID属性为“Msg”。
