怎么在c#中加入HTML代码

怎样在c#中加入HTML代码？
我想实现直接用C#显示出HTML代码。应该怎么写？就是用C#根据数据的多少自动的添加表格的行数。
例如我想在c#中加入下面的html代码，应该怎么写？
<tr valign="top" align=center>
<td height="20" style="width: 201px">
</td>
</tr>
[解决办法]
用Response.write()输出。
大致思路：
1、在本页面的后台声明一个ArrayList对象list，并对该对象赋值（可以在onload里面也可以是后期调用方法，这个根据不同需要而定）。
2、在页面源码模式下调用该ArrayList对象<% for(int i=0;i<list;i++)  %>
3、在循环中直接用Response.write（）输出即可以实现。

给楼主一个事例——百度分页的实现：
这个和你想要方法思路是一样的

 <%
                        if (currentPage > pageCounts)       //如果当前页大于总页数，就设置当前页码为总页数
                        {
                            currentPage = pageCounts;
                        }
                        if (currentPage < 1)        //如果当前页小于1，就设置当前页码为1
                        {
                            currentPage = 1;
                        }
                        if (currentPage != 1)           //当页码大于1的时候显示“上一页”
                        {
                            Response.Write("<a href="ShengLuo.aspx?page=" + (currentPage - 1) + "">上一页</a>");
                        }
                        if (currentPage - 4 > 1)        //如果显示的最小页码不是1，则在最小页码前添加省略号
                        {
                            if (currentPage - 4 > 4)
                            {
                                Response.Write("<a href="ShengLuo.aspx?page=" + 1 + "" style="text-decoration:none">&nbsp;&nbsp;1&nbsp;&nbsp;</a>"); 
 
                                Response.Write("<a href="ShengLuo.aspx?page=" + 2 + "" style="text-decoration:none">&nbsp;&nbsp;2&nbsp;&nbsp;</a>");
                                Response.Write("<a href="ShengLuo.aspx?page=" + 3 + "" style="text-decoration:none">&nbsp;&nbsp;3&nbsp;&nbsp;</a>");
                                Response.Write("<a href="ShengLuo.aspx?page=" + (currentPage - 4 - 1) + "" style="text-decoration:none">...&nbsp;&nbsp;</a>");
                            }
                            if (currentPage - 4 <= 4)
                            {
                                Response.Write("<a href="ShengLuo.aspx?page=" + (currentPage - 4 - 1) + "" style="text-decoration:none">...&nbsp;&nbsp;</a>");
                            }
                        }
                        for (int j = 1; j < 5; j++)    //写出前4页页码
                        {
                            if (currentPage - (5 - j) <= 0)
                            {
                                j = 5 - currentPage;
                                continue;
                            }
                            if (currentPage - (5 - j) > 0)

                                continue;
                            }
                            break; 
                        }

                        Response.Write("<a href="ShengLuo.aspx?page=" + currentPage + "" style="text-decoration:none">" + currentPage + "&nbsp;&nbsp;</a>");   //写出本页页码

                            }
                        }
                        //如果最大页码小于总页数，则在最大页码右侧添加省略号
                        if (currentPage + 4 < pageCounts - 4)
                        {
