using?System;
using?System.Text;
namespace?ConsoleApplication1
{
public?class?Data
{
public?Data(string?str)
{
Console.WriteLine(str);
}
public?Data(int?num)
{
Console.WriteLine(num);
}
}
class?Program
{
static?void?Main(string[]?args)
{
Data?d1?=?new?Data("test");
Data?d2?=?new?Data(1234);
Console.ReadKey();
}
}
}
