Hi Patrick,
Assuming you have the next C# class in C:\CustomAssembly.dll:
namespace ClassLibrary2
{
public class Class1
{
public Class1(int a)
{
Console.WriteLine(a);
}
public Class1(int a, string s)
{
Console.WriteLine("{0} and {1}",a,s);
}
public Class1(bool b)
{
Console.WriteLine("b = {0}",b);
}
}
}
There are several constructors here. All you have to do to call a specific
constructor via IronRuby, is to get the constructor method object (with
clr_ctor like Tomas said), use the overload method to pick up the needed
overload and call it.
For example, the next IronRuby code executes all three constructors of the
custom class above:
require 'c:\CustomAssembly.dll'
include ClassLibrary2
# Call Class1(int a) constructor:
Class1.clr_ctor.overload(System::Int32).call 1
# Prints "1"
# Call Class1(int a, string s) constructor
Class1.clr_ctor.overload(System::Int32, System::String).call 1, "yes"
# Prints "1 and yes"
# Call Class1(bool b) constructor:
Class1.clr_ctor.overload(System::Boolean).call true
# Prints "b = true"
Hope it helps,
Shay.
