Hi,<\/p>\n

when working with X# and Vulcan.NET, I have created this particular sample. It should help understand how delegates work (and that they are immutable):<\/p>\n

\n#using DelegateSample<\/p>\n

begin namespace DelegateSample<\/p>\n

public delegate SampleDelegate( cParameter as string ) as void <\/p>\n

function Start( ) as void
\n  local oSample as SampleClass
\n  local oSample2 as Sample2Class
\n  local oDelegate as SampleDelegate
\n  local oDelegate2 as SampleDelegate<\/p>\n

  System.Console.WriteLine(“Start SampleDelegate”)<\/p>\n

  oSample := SampleClass{}
\n  oSample2 := Sample2Class{}<\/p>\n

  oDelegate := SampleDelegate{ oSample:Method1 }
\n  oDelegate += oSample:Method2
\n  oDelegate += oSample2:Method3<\/p>\n

  oDelegate( “Hi” )
\n  oDelegate2 := oDelegate<\/p>\n

  oDelegate -= oSample:Method2
\n  oDelegate -= oSample2:Method3<\/p>\n

  oDelegate( “Hott” )
\n  oDelegate2( “Hups” )<\/p>\n

  return<\/p>\n

class SampleClass<\/p>\n

  constructor()<\/p>\n

  return<\/p>\n

  public method Method1( cParameter as string ) as void<\/p>\n

    System.Console.WriteLine( “method1, parameter ” + cParameter )<\/p>\n

    return\t\t<\/p>\n

  public method Method2( cParameter as string ) as void<\/p>\n

    System.Console.WriteLine( “method2, parameter ” + cParameter )<\/p>\n

    return\t\t<\/p>\n

end class <\/p>\n

class Sample2Class<\/p>\n

  public method Method3( cParameter as string ) as void<\/p>\n

    System.Console.WriteLine( “method3, Sample2Class, parameter ” + cParameter )<\/p>\n
