Get a pointer to the start of a string and display the contents of string via pointer : Pointer « unsafe « C# / CSharp Tutorial






using System; 
 
class MainClass { 
  unsafe public static void Main() { 
    string str = "this is a test"; 
 
    fixed(char* p = str) { 
      for(int i=0; p[i] != 0; i++) 
        Console.Write(p[i]); 
    } 
    Console.WriteLine(); 
  } 
}
this is a test
