How to define a class in C#

Question

I am new to C# and I want somthing that works like this in C++

#define PointCloud List<PointData>

wherer PointData is a small class which contains some data about a point and List is the generic List.

Greetings

//edit: PS: Is there a name for the thing I am searching? If there is one, please tell me.

You can use `using PointCloud = System.List` to create an alias available within that source file. But C# does not support proper typedefs which are available from other files. Depending on the context, deriving `PointCloud` from `List` might be an alternative. — CodesInChaos, Apr 16 '15 at 10:25

I guess you don't mean class, instead you can use a "Using Alias Directive". The syntax for this is as follows:

using PointCloud = System.Collections.Generic.List<PointData>;

Just create a new definition for PointCloud

class PointCloud : List<PointData>
{
}

class PointData
{}

I think the OP is looking to alias List and not actually create a new class. – BenjaminPaul Apr 16 '15 at 10:28
this is not what I asked for, but it even works better for my case, since I can use `PointCloud` in each script. Thanks! – liquid.pizza Apr 16 '15 at 10:44
