Question

The C# 3.0 spec has the following code example in section 10.6.1.3 ‘Output parameters’:

using System; class Test {     static void SplitPath(string path, out string dir, out string name) {         int i = path.Length;         while (i > 0) {             char ch = path[i – 1];             if (ch == '\\' || ch == '/' || ch == ':') break;             i--;         }         dir = path.Substring(0, i);         name = path.Substring(i);     }     static void Main() {         string dir, name;         SplitPath('c:\\Windows\\System\\hello.txt', out dir, out name);         Console.WriteLine(dir);         Console.WriteLine(name);     } } 

I cannot get this code to compile in VS2005/C#2.0. Did the behavior of strings in C# 3.0 change so that a string can be referred as a char[] array without explicitly converting it (the statement ‘ch = path[i – 1]’)?

Answer 1

It is an invalid character ‘–’. Change ‘–’ to ‘-‘
