vb.net错误：无法访问由于其保护级别 [英] vb.net error: inaccessible due to its protection level
本文介绍了vb.net错误：无法访问由于其保护级别的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我工作的第1次用vb.net code，但我有一个C＃5年工作经验。
从previous开发者，我被告知，code这是在服务器上运行正常，没有任何错误，但只要我一打开网页文件夹（网站没有解决方案文件），我试着建立网站和我说吨的错误：
I am working for 1st time with vb.net code, but I have 5 years experience with C#. From the previous developer I was told that the code which is on the server runs fine without any errors, but as soon as I opened the website folder (the website doesn't have solution file), I tried to build the site and I got tons of errors saying:
labelControl'未声明。它可能无法访问由于其
保护级别。
'labelControl' is not declared. It may be inaccessible due to its protection level.
这是怎么回事全部两个我打开到目前为止页面的控制。老实说，我很害怕，打开更多的网页:)。
That's happening for all the controls on two of the pages I opened so far. Honestly I am afraid to open more pages :).
下面是该文件中的一个标记，逻辑和设计师code部分：

下面是一些我收到的错误：
Here are some of the errors I am getting:
请让我知道你的想法可能是原因。
我期待着听到您的到来。
谢谢，Laziale
Please let me know what you think can be the reason. I look forward to hear from you soon. Thanks, Laziale
推荐答案
如果您code是逐字复制，然后在逻辑块类名称拼写错误和不匹配，在设计文件中的名称。此它会导致PTED作为两个独立的类间$ P $，这会导致错误。在一个文件中的code不是能引用在其它文件中定义的对象。
在逻辑块修复类的名称相匹配的设计师块和错误应该消失。
修改：我注意到它在标记文件的第一行拼错为好。一定要修复类的名称也有。
If your code is copied verbatim, then the class name in the Logic block is misspelled and doesn't match the name in the designer file. This causes it to interpreted as two separate classes, which causes the errors. The code in the one file is not able to reference objects defined in the other file.
Fix the class name in the logic block to match the designer block and the errors should go away.
Edit: I noticed it was misspelled in the first line of the markup file as well. Be sure to fix the class name there too.
