Why is generic constructor not allowed?
Generic argument is not allowed in the constructor. When I compile the code below I get a compilation error saying:
error CS1519: Invalid token '(' in class, struct, or interface
member declaration
The reason is simple. You can have a class Foo<T> and a class Foo as described in my previous post. Now when you says
fooInstance = new Foo<T>();
there is no way for the compiler to find out the right class constructor to call.
namespace Sample
{
using System;
public class Foo <T>
{
}
class Foo
{
public Foo<T>()
{
Console.WriteLine("This is generic Foo class {0}",typeof(T));
}
}
public class Bar
{
static public void Main()
{
Foo fooGenericInstance;
fooGenericInstance = new Foo<Int32>();
}
}
}
