C#.Net Generics
Generics is not a completely new concept, similar concept exist with other languages also. In C++, templates can be compared to generics. Generics allow you to define a class with some specific data type at compile time. A generic class can be defined using angle brackets <>.
Example 1: C#.Net Generic
namespace ConsoleApplication1
{
class example<t>
{
public void square(t num)
{
if (num.GetType().ToString() == "System.Int32")
{
int n = Convert.ToInt32(num.ToString());
Console.WriteLine("Square of 10 is " + n * n);
}
else
{
Console.WriteLine("Invalid Number:" + num);
}
}
}
class Program
{
static void Main(string[] args)
{
example<int> ex = new example<int>();
ex.square(10);
example<string> ex2 = new example<string>();
ex2.square("abc");
Console.ReadKey();
}
}
}
