Hi i have strange problem. Here is my code:

How can I get rid of that "\u0013"?
Normally I will do it with substring or something but I have some issues with that character ---> \
Could someone help me?

You can use tmp.TrimEnd('\u0013') if it is single char or tmp.Replace("\\u0013", string.Empty) if it is sequence of chars to get "20_29" part:

You should replace two newline characters(if any). Following code will work on Unix as well as non unix platforms.
var stringWithoutEmptyLines = yourString.Replace(Environment.NewLine + Environment.NewLine, Environment.NewLine);

string data = stringData.Replace("\r\n\r\n", "\r\n");

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.
