As long as your string value is not private, you should be able to do something like this只要您的字符串值不是私有的，您就应该能够做这样的事情
<input type="text" value="<%= YourStringValue %>" />

You could use an actual <asp:Textbox /> and set it's "text" value directly from the code behind.您可以使用实际的<asp:Textbox />并直接从后面的代码中设置它的“文本”值。 If you want to directly inject text into a "normal" html textbox (or anywhere else for that matter), you can use <%= SomeValue %> .如果您想直接将文本注入“普通” html 文本框（或其他任何地方），您可以使用<%= SomeValue %> 。 Yet another way is to include the "runat=server" attribute on standard html elements, allowing you to manipulate them from the codebehind.另一种方法是在标准 html 元素上包含"runat=server"属性，允许您从代码隐藏中操作它们。
Normally I'd just go for the built-in ASP textbox control so I don't have to worry about persisting values/wiring up viewstate/etc.通常我只需 go 用于内置 ASP 文本框控件，因此我不必担心持久值/连接视图状态等。 Injecting dynamic content into plain html elements tends to be an edge case requirement...将动态内容注入普通的 html 元素往往是边缘情况要求......
