推荐答案

我会说你几乎肯定做错了.您是否在许多项目中都尝试过?您确定文件不是只读的吗?您选择一个控件，然后单击该表单将其添加? I would say you''re almost certainly not doing it right. Have you tried it across many projects ? Are you sure the files are not read only ? You select a control, then click the form to add it ?

1-请不要按"answer"来发布非答案 2-您希望我们做什么?我该如何修理您的计算机? Visual Studio适用于使用它的每个人，因此，除了您的安装以外，我看不到任何问题，或者，如果您删除并重新安装了该程序，那么问题就是我列出的问题之一.我们肯定会根据您含糊不清的帖子为您提供帮助. 1 - please don''t push ''answer'' to post a non answer 2 - what do you expect us to do ? How can I fix your computer ? Visual Studio works for everyone who uses it, so, I don''t see how the problem can be anything but your install or, if you''ve removed and reinstalled the program, then the issue is one of the things I listed. We sure as hell cannot help you based on your vague posts.

只需在c#中创建自定义cortrol < pre lang ="cs">使用System.ComponentModel; 使用System.Security.Permissions; 使用System.Web; 使用System.Web.UI; 使用System.Web.UI.WebControls; 命名空间Samples.AspNet.CS.Controls { [ AspNetHostingPermission(SecurityAction.Demand， 级别= AspNetHostingPermissionLevel.Minimal)， AspNetHostingPermission(SecurityAction.InheritanceDemand， Level = AspNetHostingPermissionLevel.Minimal)， DefaultProperty(& quot;文本& quot;)， ToolboxData(& lt; {0}:WelcomeLabel runat = \&服务器\& quot;& lt;/{0}:WelcomeLabel& quot;) ] 公共类WelcomeLabel:WebControl { [ 可绑定(true)， 类别(外观")， DefaultValue(&&")， 说明(&欢迎消息文本.")， 可本地化(true) ] 公共虚拟字符串Text { 获取 { 字符串s =(string)ViewState [& quot; Text& quot;] ;; 返回(s == null)吗?
