issue escaping charceter for json using regex

Question

Trying to escape special characters for json using following code

Dim testString As String = "this ""word"" is escaped"

Dim retruString = System.Text.RegularExpressions.Regex.Replace(testString, "\\([^""\\/bfnrtu])", "\\")

I know I have overlooked something really silly or maybe its been a long day/night, if anyone can point to my mistake would be greatly thankful

There is no error but the retruString is not escaped.

In .NET 4, you do not need a regex:

retruString = System.Web.HttpUtility.JavaScriptStringEncode(testString)

For older .NET versions, check out this post: How to escape JSON string?
