Why does Html.ActionLink render "?Length=4"
📝 Why does Html.ActionLink render "?Length=4"?
Are you confused about why your code for rendering a link in HTML is resulting in an unexpected "?Length=4" at the end of the link URL? Don't worry, you're not alone! This blog post aims to shed some light on this common issue and provide you with easy solutions to fix it.
🔍 Understanding the Problem To understand why you're seeing "?Length=4" in the rendered link, let's break down the code snippet you provided:
Html.ActionLink("About", "About", "Home", new { hidefocus = "hidefocus" })This code is using the Html.ActionLink method, which is typically used to generate an anchor tag with a specific URL. The parameters passed to this method specify the link text ("About"), the action ("About"), the controller ("Home"), and an anonymous object with additional HTML attributes ("hidefocus").
By default, when you use Html.ActionLink, it will include route values as query string parameters in the generated URL. In this case, since there are no additional route values, it adds "?Length=4" to the end of the URL.
🔧 Easy Solutions To fix this issue and get rid of the "?Length=4" from the URL, you have a couple of options:
Specify
nullfor the route values parameter:
Html.ActionLink("About", "About", "Home", null, new { hidefocus = "hidefocus" })By passing null as the route values parameter, you're telling the method to not include any additional route values in the URL.
Use an overload that does not include route values:
Html.ActionLink("About", "About", "Home")If you don't have any additional route values to include, you can simply omit the route values parameter altogether.
