如何使用 C# 添加 html 样式容器？

发布于 2024-10-22 23:45:55 字数 283 浏览 6 评论 0原文

我需要在特定页面的部分中添加 HTML 样式容器，如下所示：

<style>
#mycontrol
{
    color:#ff0000;
}
</style>

虽然有很多方法可以做到这一点，但我正在考虑从 System.Web.UI.HtmlControls 命名空间实例化 HtmlControl 并简单地呈现它在页面上。但是，我只发现 HtmlGenericControl 是最接近的候选者 - 是否有更合适的控件可以使用，或者我是否必须使用其他方法？

I need to add a HTML style container in the section of a particular page, like so:

<style>
#mycontrol
{
    color:#ff0000;
}
</style>

Although there are quite a few ways of doing this I was thinking about instantiating a HtmlControl from the System.Web.UI.HtmlControls namespace and simply render it on the page. However I only found the HtmlGenericControl to be the closest candidate - is there a more suitable control I can use or do I have to use another approach?

尝试类似

HtmlGenericControl style = new HtmlGenericControl();
style.TagName = "style";
style.Attributes.Add("type", "text/css");
style.InnerHtml = "body{background-color:#000000;}";
Page.Header.Controls.Add(style);

Try something like

HtmlGenericControl style = new HtmlGenericControl();
style.TagName = "style";
style.Attributes.Add("type", "text/css");
style.InnerHtml = "body{background-color:#000000;}";
Page.Header.Controls.Add(style);

你可以试试这个：

    var myStyle =
        new Style { ForeColor = System.Drawing.Color.FromArgb(255, 0, 0) };

    Page.Header.StyleSheet.CreateStyleRule(myStyle, this, ".myStyle");

you can try this:

    var myStyle =
        new Style { ForeColor = System.Drawing.Color.FromArgb(255, 0, 0) };

    Page.Header.StyleSheet.CreateStyleRule(myStyle, this, ".myStyle");

您可以使用 HtmlGenericControl - 或者如果您愿意，也可以使用 Literal。

更好的方法可能是使用

  protected void Page_Load(object sender, System.EventArgs e)
  {

      // Create a Style object for the body of the page.
      Style bodyStyle = new Style();

      bodyStyle.ForeColor = System.Drawing.Color.Blue;
      bodyStyle.BackColor = System.Drawing.Color.LightGray;

      // Add the style rule named bodyStyle to the header 
      // of the current page. The rule is for the body HTML element.
      Page.Header.StyleSheet.CreateStyleRule(bodyStyle, null, "body");

      // Add the page title to the header element.
      Page.Header.Title = "HtmlHead Example"; 

  }

You can use an HtmlGenericControl - or you can use a Literal if you want to.

A better way might be to insert this into your HTML Header using something like this code from http://msdn.microsoft.com/en-us/library/system.web.ui.page.header.aspx

  protected void Page_Load(object sender, System.EventArgs e)
  {

      // Create a Style object for the body of the page.
      Style bodyStyle = new Style();

      bodyStyle.ForeColor = System.Drawing.Color.Blue;
      bodyStyle.BackColor = System.Drawing.Color.LightGray;

      // Add the style rule named bodyStyle to the header 
      // of the current page. The rule is for the body HTML element.
      Page.Header.StyleSheet.CreateStyleRule(bodyStyle, null, "body");

      // Add the page title to the header element.
      Page.Header.Title = "HtmlHead Example"; 

  }
