Question

我无法理解问题所在。我收到的错误是：

＆＃39; ASP.newevents_aspx＆＃39;不包含＆＃39; BUSAVEInfo_Click＆＃39;的定义没有扩展方法＆＃39; BUSAVEInfo_Click＆＃39;接受类型＆＃39; ASP.newevents_aspx＆＃39;的第一个参数。可以找到（你错过了使用指令或汇编引用吗？）我觉得我已经做好了一切。请让我知道我错过了什么。我已经学习了几个星期的ASP.NET。感谢。

Answer 1

这是你的大写。 BUSaveInfo_Click是方法的名称，但BUSAVEInfo_Click是标记中的内容。

他们需要匹配。

ASP.NET定义错误
