Activator Class : How to

[Ian Semmel]

I may be way off track here but ...

I can do this :

DataGridViewColumn col = new DataGridViewCheckBoxColumn ();

but if I have this

Type t = typeof (DataGridViewCheckBoxColumn );

and I want something (like this which is wrong )

DataGridViewColumn col = Activator.CreateInstance ( t );

This doesn't work because you get the error 'Cannot implicitly convert object to
DataGridViewColumn ...'

What methods etc (if any) do I use to get around this without having to do an
explicit conversion ?

Hi,

You almost had it. When the compiler says that it can't implicitly convert,
meaning that it is not an automatic conversion to the new type, you'll need
to add it yourself in the form of a cast...
....
DataGridViewColumn col = (DataGridViewColumn)Activator.CreateInstance ( t );
