Question

I have tried something like this

  string path= Server.MapPath("~") + "color\";

But its throwing an error

“New line in constant”

Is there any way to append "\" in a string ?

Answer 1

Use a verbatim string literal

string path= Server.MapPath("~") + @"color\";

or \\

string path= Server.MapPath("~") + "color\\";

The problem is that \ escapes the closing ", that’s why this doesn’t work:

string invalid = "color\"; // same as: "color;

However, you should really use the Path class and it’s methods if you’re building paths as codingbiz has already mentioned in his answer. It will make your code more readable and less error-prone
