不包含定义,也没有扩展方法错误
问题描述:
尝试调用我创建的名为AddCustomer
的Web服务方法时出现以下错误。它强调AddCustomer当我做pxy.AddCustomer(txtLogin.Text)
不包含定义,也没有扩展方法错误
“AuctionService”不包含“AddCustomer”,没有扩展方法“AddCustomer”接受型“AuctionService”的第一个参数的定义可以找到(是否缺少使用指令或程序集引用)

}
答
Project4WS
和Project4
是两个不同的名称空间。因此protected void AddCustomer
方法不能在btnNewUser_Click
方法中访问。为AddCustomer
函数设置访问修饰符public
。
答
变化,从保护公众
更改方法AddCustomer'的'访问修饰符从'protected'到'方法
AddCustomer
的访问修饰符public' –仍然得到同样的错误,当我将其改为公开 – Alex
