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

I am trying to do a string replace for website names. Here is the code:
string output = input.Replace("C:\Design\Website\", "Someting");
TextBox.Text = osc.output;
The code is incorrect as there is an issue \ with these marks. How can I fix my code?

You need to escape the \:
Either:
"C:\\Design\\Website\\"
Or:
#"C:\Design\Website\"

What does "#" mean before a string?
I saw this notation with paths:
string myfolder = #"C:\Users\";
But also with normal strings.

It means it's a literal string, so won't treat \ as an escape character, for example. This page should help you understand it better.

Equivalent to Javascript's encodeURI? [duplicate]

C#'s equivalent to encodeURIComponent is well-covered on SO and elsewhere, but what about encodeURI? Basically I want to encode invalid URL characters only and not reserved characters such as /, :, etc. So
"http://www.example.com/my cool page"
would be encoded to
"http://www.example.com/my%20cool%20page"
Is there something baked into .NET to do this? Or is a regex my best bet?

Try
Uri.EscapeUriString("http://www.mysite.com/my cool page")

Try
Server.URLEncode(uri.ToString)

Try this:
HttpUtility.UrlEncode(String)
For example:
var url_encoded_string = HttpUtility.UrlEncode(userInput);

You could use System.Net.WebUtility.UrlEncode(string value).

How to build a query string for a URL in C#?

I have to write this data in querystring:
http://localhost:1256/4.market.ph.local/WEP/Add.cshtml?data=me+&+you
I got an error because of that symbol '&' i used.

In c# you can use this:-
HttpUtility.UrlEncode("http://localhost:1256/4.market.ph.local/WEP/Add.cshtml?data=me+&+you");
HttpUtility is a part of System.Web and this will ensure an of the non permitted query string char are url Encoded.
Once you do this you will get something like this http%3a%2f%2flocalhost%3a1256%2f4.market.ph.local%2fWEP%2fAdd.cshtml%3fdata%3dme%2b%26%2byou
On the receiver just decode it back.

Use urlencode($yourstring) or if you are hard coding it, use %26 to represent the ampersand.
