一个小问题?

Question

private  void  Button1_Click(object  sender,  System.EventArgs  e)  
                       {  
                                   bool  check;  
                                   string  name=TextBox1.Text;  
                                   string  mima1=TextBox2.Text;  
                                   string  mima2=TextBox3.Text;  
                                   if(mima1!=mima2)  
                                   {  
                                               TextBox1.Text="密码不匹配,请重新输入!";  
                                   }  
                                   else  
                                   {  
                                               check=new  localhost.Service1().regedit(name,mima1);  
                                               if(check){TextBox1.Text="新用户注册成功!";}  
                                               else{TextBox1.Text="用户名已存在,请更改用户名!";}  
                                   }  
编译时错误出现为:找不到类型或命名空间名称“localhost”(是否缺少  using  指令或程序集引用？)  
请问怎么改正?

Answer 1

new  localhost.Service1().是什么?

Answer 2

localhost.Service1().regedit(name,mima1);  
一定是别的地方的代码，FCL里没有这些东东。
