As I read the question since I have similiar issue about the backslash. On my webform textbox, I input some thing on like VN\Mary. I would like to Split this textbox.Text as 2 words. the Split worked very well in VB.Net , after I moved to C#, it starts to have problem. Would anyone give me some advice ? I even tried textbox.Text.ToCharArray() but it does not work if I use VN\Thomas. I would appreciate your advice. Thank you.

  • You need to escape backslashes in C#. Try `textbo.Text.Split( new Char[] { '\\' } )`. – Dai Oct 03 '22 at 13:37

    Uhm, is `VN\Thomas` meant to represent a Windows Active Directory login name? – Dai Oct 03 '22 at 13:37

string[] words = textbox.Text.Split('\\');

EDIT: escape the backslash

    This doesn't compile: `'\'` is an invalid `char` literal: backslashes must be escaped. – Dai Oct 03 '22 at 13:56
  • hi @peemerdu, I checked, the function is working but it does not work on WebApi when I pass object as `{ "loginID": "a2vn\thomasl", "password": "password", } ` by using the same `Text.Split('\\')` , it does not work. Would you have suggestion ? – Tài Lê Hữu Oct 03 '22 at 14:38
  • @TàiLêHữu - You could do this a few ways which is outside the scope of the original question. Is this in JSON format? I would parse this into an object and run the above solution against the value of the property. – peemerdu Oct 04 '22 at 09:57
