How to render a self closing tag using TagBuilder in C#?

In C#, you can use the TagBuilder class to render a self-closing tag by setting its TagRenderMode property to TagRenderMode.SelfClosing. The TagRenderMode.SelfClosing option indicates that the tag should be rendered as a self-closing tag in the output HTML.

Here's how you can render a self-closing tag using TagBuilder:

using System; using System.Text; using System.Web; public class Program { public static void Main() { // Create a self-closing tag for <img /> TagBuilder imgTag = new TagBuilder("img"); imgTag.Attributes.Add("src", "image.jpg"); imgTag.TagRenderMode = TagRenderMode.SelfClosing; // Render the self-closing tag string renderedImgTag = imgTag.ToString(TagRenderMode.SelfClosing); Console.WriteLine(renderedImgTag); } }

Output:

<img src="image.jpg" />

In this example, we use the TagBuilder class to create a self-closing <img /> tag. We add the src attribute to the tag and set its TagRenderMode property to TagRenderMode.SelfClosing. The ToString method of the TagBuilder class is then used to render the tag as a self-closing tag.

You can apply the same approach to render other self-closing tags such as <br />, <hr />, or any custom HTML tags that are meant to be self-closing in your application.
