I want to replace all occurences of multiple slash ('') with single backslash

For example

mama\\\\Please\\\\\U0U0001f973\U00.txt

Result  should be this
mama\Please\U0U0001f973\U00.txt

I have tried

string file = "mama\\\\Please\\\\\U0U0001f973\U00.txt"
string output = Regex.Replace(file, @"[/\\]{2,}", @"\");

current result

mama\\Please\\\U0U0001f973\U00.txt

You could use `(\\)+\1` and replace it with two back slashes, or how many slashes you need – Buttered_Toast Nov 29 '22 at 14:47
See https://ideone.com/t7Fx3T, your code almost works if you define the string properly. – Wiktor Stribiżew Nov 29 '22 at 14:48
