如何将字符串可以把用户控件 [英] How to a string can turn a UserControl

问题描述

时有什么方法/可能性，我可以用一个用户控件替换字符串？

Is there any ways/possibilities that I can replace a string with a UserControl?

除了LoadControl并将其添加到像页或占位另一个控制

apart from LoadControl and adding it to another control like page or placeholder.

原因是用户在页面上添加内容，并把像一个字符串{UC：测试}，我想解析这个文本和替换。{UC：测试}与用户控件

The reason is that a user add a content on the page and put a string like {uc:test} and I would like to parse this text and replace {uc:test} with a UserControl.

换言之;
用户输入将是唧唧歪歪{UC：测试}喇嘛喇嘛，当我找回它从数据库我怎么可以注入用户控件并将其替换为{UC：测试}

in other words ; The user input will be "bla bla bla {uc:test} bla bla", when I retrieve it from database how can I inject usercontrol and replace it with {uc:test}

感谢。

推荐答案

尝试LoadControl方法动态加载的用户控件和回发期间将它们添加到您的网页。

Try the LoadControl method to dynamically load user controls and add them to your page during postback.

Control someControl = LoadControl("~/SomeControl.ascx");

您可以...将它添加到你的页面的控件集合：

You could... Add it to your page's control collection:

        this.Page.Controls.Add(someControl);

或者......将它添加到另一个控件的控件集合

Or... Add it to another control's control collection

        someExistingPlaceHolder.Controls.Add(someControl);

如何获取标签这样使用正则表达式

How about getting the tags like this using regex

List<string> fields = new List<string>(); 
foreach(Match match in Regex.Matches(str, @"\{([^\}]*)\}")) { 
    fields.Add(match.Groups[1].Value); 
}
