I have classitems whose unique identifier is their stringfield. I am set these elements in html using Razor(C#). I handle it for javascript. I need to convert strings from example"Mr. Smith" to id"{2342-2341-2324-...}" or at Base64"92384098230...". And then use javascript to get the value from the encoded string. How to do it in C# and Javascript?

You could do the following-

C# - Uri.EscapeDataString(String)

And to convert the above value in JavaScript-

js - unescape(string) or decodeURI(string)

If you would like to do the reverse you can use

C# - Uri.UnEscapeDataString(string) & js - escape(string) or encodeURI (string)

  • Thank you, this is what need. But it doesn't work - when converting back, I get Ðвод%20инÑоÑмаÑии – Nik Volk Sep 16 '21 at 04:16
  • Can you share a bit more details? C# what's is the original text and escaped text and in js unescaped text? – Joel Pusanur Sep 16 '21 at 04:20

    I did it! The "unescape" method is deprecated, I replaced it with "decodeURI": C#:`Uri.EscapeDataString(item.Name)` => Javascript:`decodeURI(itemId)`. Its work! Thanks! – Nik Volk Sep 16 '21 at 04:24
  • Added decodeURI in the answer - however https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/unescape – Joel Pusanur Sep 16 '21 at 04:36
