推荐答案

这很容易用Google搜索.如果您用谷歌在运行时更改主题"，则第一个结果将在此站点上出现:

This is very easily googled. If you google "change themes at runtime" the first result is on this very site: How to change page theme in asp.net 2.0 dynamically at runtime[^] and it answers your question.
Please google your question first.

我发现此链接非常有用:

我添加了主题:在我的项目中为白色，黄色和红色.

I added themes : As White , Yellow and Red In my Project .

To add theme :

<asp:button runat="server" xmlns:asp="#unknown">
  BackColor="White" 
  ForeColor="Black" 
  Font-Name="Times New Roman" 
  Font-Size="12px" />


<asp:button runat="server">
  BackColor="Red" 
  ForeColor="Green" 
  Font-Name="Arial Black" 
  Font-Size="12px" />

<asp:button runat="server">
  BackColor="Yellow" 
  ForeColor="Orange" 
  Font-Name="Comic Sans MS" 
  Font-Size="12px" />



</asp:button></asp:button></asp:button>

我已经为黄色"和红色"主题选择了两个按钮，并为显示消息"添加了一个标签.代码如下

I have taken two buttons for Yellow and Red Theme and a label to Display message . Code is as below

<pre lang="HTML">
<asp:button id="btnYellowTheme" runat="server" text="Yellow Theme" style="position :absolute ; left: 76px; top: 74px;" onclick="btnYellowTheme_Click" xmlns:asp="#unknown" />       
<asp:button id="btnRedTheme" runat="server" text="Red Theme" style="position :absolute ; left: 225px; top: 74px;" height="24px" onclick="btnRedTheme_Click" xmlns:asp="#unknown" />       
<asp:label id="lblDisplay" runat="server" text="" style="position :absolute; left: 135px; top: 34px;" xmlns:asp="#unknown"></asp:label>

对于Coding Part，要动态应用主题:

For Coding Part , to apply theme dynamically :

public partial class _Default : System.Web.UI.Page 
{

    string thmName; 
    protected void Page_Load(object sender, EventArgs e)
    {
      
    }
    protected void Page_PreInit(Object sender, EventArgs e)
    {
        thmName = (string)Session["ThemeName"];
        if (thmName != null)
        {
            Page.Theme = thmName;
            lblDisplay.Text = "You have applied Theme :" + (string)Session ["ThemeName"];
        }
        else
        {
            thmName = "White";
            Page.Theme = thmName;
            lblDisplay.Text = "This is default White Theme";
        }
    }
    protected void btnYellowTheme_Click(object sender, EventArgs e)
    {
        thmName = "Yellow";
        Session["ThemeName"] = thmName;
        Session["ThemeName"] = "Yellow";
        Server.Transfer(Request.FilePath);  
    }
    protected void btnRedTheme_Click(object sender, EventArgs e)
    {
        thmName = "Red";
        Session["ThemeName"] = thmName;
        Response.Redirect("Default.aspx");
        Session["ThemeName"] = "Red";
        Server.Transfer(Request.FilePath);
    }
}
