Assuming you can slightly change the format of what you put in the database then I'd do something along these lines:

假设您可以稍微更改放入数据库的内容的格式，那么我会按照以下方式做一些事情：

string labelFromDatabase="You also have to click on is <a href=\"{0}\" target=\"_blank\"> link </a>";
string url = "mypage.aspx";
myLabel.Text = String.Format(labelFromDatabase, url);

Adding in the {0}placeholder into the database held string means you can easily just use String.Formatto put in whatever url you want.

将{0}占位符添加到数据库保存的字符串中意味着您可以轻松地使用它String.Format来放入您想要的任何 url。

Main things to be aware of are that putting {or }in the DB string will need special care (since they are special characters when you pass it into String.Format. Also you will of course need to make sure that url is appropriately escaped if necessary (but that is the case with all solutions).

需要注意的主要事项是放入{或}放入 DB 字符串需要特别小心（因为它们是特殊字符，当您将其传递到String.Format.所有解决方案的情况）。

Try to use HyperLink.

尝试使用超链接。

 <asp:HyperLink id="hyperlink1" 
                  ImageUrl="images/pict.jpg"
                  NavigateUrl="http://www.microsoft.com"
                  Text="Microsoft Official Site"
                  Target="_new"
                  runat="server"/>

you need to store your string in database with some formate like this...

您需要使用这样的格式将字符串存储在数据库中...

 "You also have to click on is <a href='{0}' target='_blank'> link </a>"

and when you assign that text to your lable at that time use string.formate method to add URL to href like this...

当您将该文本分配给您的标签时，请使用 string.formate 方法将 URL 添加到 href 像这样...

//get your database string
string _samplestring ="You also have to click on is <a href='{0}' target='_blank'> link </a>";
string _url ="http://stackoverflow.com/";
lbl.Text = string.Format(_samplestring, _url);

if you also need to assign something to target at run time then store your string like this..

如果您还需要在运行时为目标分配一些东西，那么像这样存储您的字符串..

"You also have to click on is <a href='{0}' target='{1}'> link </a>"

and use it like this...

并像这样使用它......

//get your database string
string _samplestring ="You also have to click on is <a href='{0}' target='{1}'> link </a>";

lbl.Text = string.Format(_samplestring, _url,_target);

Use the following code for assigning string to href in anchor tag which is created in code behind

使用以下代码将字符串分配给在后面的代码中创建的锚标记中的 href

string strstring = "../master/YourPage.aspx?TransID="+ dr["TransId"];

string strstring = "../master/YourPage.aspx?TransID="+ dr["TransId"];

Assign this string to url

将此字符串分配给 url

marqueeText += "<a href='"+strstring+"'" + <span style='color:red;font-weight:bold;font-size:16px'>"
+ Convert.ToString(dr["SocietyName"]) + "</span></a>";

Hope this will help you.

希望这会帮助你。

You should add runat="server" to your anchor and then give an ID to it. So you can edit href property in codebehind.

您应该将 runat="server" 添加到您的锚点，然后为其提供一个 ID。因此，您可以在代码隐藏中编辑 href 属性。

in html side:

在 html 端：

in code behind: xxxxx.HRef = "bla bla"

在后面的代码中：xxxxx.HRef = "bla bla"

Look at this: How do you set href attribute of anchor tag that is within a repeater in code behind?
