错误CS0103 [英] Error CS0103
问题描述
我目前正在学习Web Dev，我目前的评估是关于c＃。我正在完成我的最后一页，我多次得到同样的错误。它是通过客户网站加入的邮件列表的网络表单。这个c＃布局已经在我的
其他网页表单页面上工作了，但是这个页面让我很头疼。这是我在下面的内容，错误是CSID103（'xxxxx'在当前上下文中不存在）subID.Text，subName.Text，SubEmail.Text，subAddress.Text，subPhone.Text和subSex.Text。
我缺少什么？

您好，
请考虑在ASP.NET论坛中提出这个问题。
I'm currently studying Web Dev and my current assessment is about c#. I am finishing my last page and I am getting the same error multiple times. It is a webform for a mailing list people join through the clients website. This c# layout has worked on my other web form pages but this page is giving me a headache. This is what I have below and the errors are CS0103 ('xxxxx' does not exist in current context) for subID.Text, subName.Text, SubEmail.Text, subAddress.Text, subPhone.Text and subSex.Text.
What am I missing?
