CLR DateTime type is currently mapped to Time Ruby class, so "new" uses only Ruby constructors to be compatible. However, you can use clr_new to call the CLR constructor for any CLR type with a public constructor: Time.clr_new(2009, 9, 28) You can also get the constructor method and call it like so: Time.clr_ctor.call(2009, 9, 28) This is useful when there are multiple overloads of the constructor among which we are not able to choose based upon the types of the actual arguments.

Hi That is fine in this case, can you tell me, in cases where I can''t fall back on a ruby class, is there a way to call an overloaded constructor? Your reply makes me worry a bit more.

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.

Hello Thank you all for your help and I have to say that I am sorry also, I missed the other replies where you came right out and told me how to do it, for some reason I only saw the one that mapped the DateTime to the Time object, you all provided very good answers to my question and I really appreciate it.
