In c# 3.0, is it possible to add implicit operators to the string class?
c#, implicit
Solution
No, there's no such thing as extension operators (or properties etc) - only extension methods.
The C# team have considered it - there are various interesting things one could do (imagine extension constructors) - but it's not in C# 3.0 or 4.0. See Eric Lippert's blog for more information (as always).
Problem
something like ``` public static class StringHelpers { public static char first(this string p1) { return p1[0]; } public static implicit operator Int32(this string s) //this doesn't work { return Int32.Parse(s); } } ``` so : ``` string str = "123"; char oneLetter = str.first(); //oneLetter = '1' int answer = str; // Cannot implicitly convert ... ```
