What does this code do?

Question

For Each tag As HtmlTag In tags
    insertTextBuilder.Remove(0, insertTextBuilder.Length)
    insertTextBuilder.AppendFormat("<{0}", tag.Name)

Answer 1

I'm going to assume here that insertTextBuilder is a StringBuilder.

• take each tag in the collection, type it as HtmlTag.

For each tag:

• Erase the string builder's value. Remove() from index 0 to the length of the stringbuilder's value.
• put in text "<something"

You'll be left with the last value in the loop. In other words, do a whole bunch of work, always erase what you previously did, and end up with "<something", whatever the LAST tag was in the collection.

Was there a specific line of code, or method call that you were interested in?

Answer 2

As far as I can see it's going to leave string builder with a < and then the contents of the 'Name' for the last tag in the collection "tags". Lot of effort for not much content.
