Question

I need a regex to move all alphabets from string (A-Z) and (a-z)..everything including any kind of special character should remain intact. I tried @”[^\d]” but it only returns numbers in string.

String : asd!@# $%dfdf4545D jasjkd #(*)jdjd56

desired output : !@# $%4545 #(*)56

Answer 1

Just replace all undesired characters with an empty string sequence:

string filtered = Regex.Replace(input, "[A-Za-z]", "");
