将HTML ID添加到.aspx文件中的标签

Question

So I'm writing an app that lets the user select a folder, it gets all the .aspx files in that folder, and lets the users check off which ones they want to add HTML ID's to.

Then they click start, and this runs

private void btnStart_Click(object sender, EventArgs e)
        {
            for (int i = 0; i < listFiles.CheckedItems.Count; i++)
            {

            }
        }

It loops through all the selected file names. How do I open each of these .aspx files in the background, and go through them and add the

id="thisItemId"

attribute to each tag that's like a , , , , , etc....

Answer 1

Assuming you know how to do basic file IO, I recommend using the HTML Agility Pack to parse the ASPX files. Using that library you can modify the HTML elements in which you're interested, and then save the file back using some more basic file IO.
