从SQL数据源渲染HTML中的换行符
我将一列的多行作为一个单行和一列返回：
SELECT STUFF((
SELECT '<br/>' + Notes
FROM DailyTaskHours
WHERE Notes IS NOT NULL
AND Notes <> ''
AND NonScrumStoryId = DTH.NonScrumStoryId
FOR XML PATH('')
), 1, 1, '')
)
我想在ASP.NET中连接的每一行之间插入换行符，但我的方法不起作用：
正如您所见，正在用数据库引擎替换<br />如何在数据库中获取换行符，以便在网页上呈现间隔？
以下是我正在处理的整个控件供参考：

5 个答案:
答案 0 :(得分：4)
您的数据库引擎没有这样做，ASP.NET正在这样做。这是一项有助于防止XSS的安全功能。
您可以在绑定字段上设置 HtmlEncode 属性，例如此MSDN链接中的示例：
<asp:boundfield datafield="City"
htmlencode="false"
headertext="City"/>
答案 1 :(得分：2)
在您的应用程序中，您可能希望对字符串执行HttpUtility.HtmlDecode。
来自MSDN：
将已经过HTML编码的HTTP传输字符串转换为已解码的字符串。
http://msdn.microsoft.com/en-us/library/system.web.httputility.htmldecode(v=vs.110).aspx
实际上，可能首选将<br />附加到应用程序本身，而不是查询中。在查询本身以这种方式按摩数据并不常见。通常，为应用程序提取的数据不应附加任何表示层或视图类型的内容，除非它确切地存在于数据库中。为您的应用程序保存该工作。例如，如果这是一个MVC应用程序，您可以考虑在控制器中执行此类工作。

现在，我从您刚刚发布的代码中看到了问题的完整背景，我将在下面为今后的读者添加相同的评论。自从我进入ASP.NET WebForms之后已经有一段时间了，所以我可能会有点生疏！我的评论......
有更好的方法可以解决这个问题，但我担心它可能超出了这个问题的范围，因为它也会涉及你如何创建数据源。如果您有兴趣，可以快速搜索
Repeater内GridView的{{1}}和两个相关数据表的数据源。这是一个旧的例子（.NET 2.0），但它可能仍然有效，或者至少应该有助于引导您找到更好的例子。
现在换另一个答案？ ...
我可以考虑针对您的问题的另一个选项。在查询中，您可以在SQL中追加一个简单的新行（<br />或char（10）），而不是附加\n。然后，不要在asp:BoundColumn中使用GridView该字段，而是使用asp:TemplateField并在模板内部，将\n替换为<br />。就像我之前说的那样，自从我完成WebForms以来已经有一段时间了，但我相信它看起来像是：
<%#Eval("Task").Replace("\n", "<br />")%>
我想您可以使用HtmlDecode执行类似操作，但我不喜欢在这些查询结果中看到HTML标记。
