c# Type Alias/Custom Type

Question

Im trying to convert some Delphi code to c# and I\'ve come across a problem...

In Delphi I\'ve decalared a new type

Type TData = Array of Extended


        

Answer 1

It sounds like you want something similar to a C/C++ typedef, which unfortunately I don't think is supported in C#. You can make local alias within a single source file (see below), but the alias won't be visible anywhere else.

To create a local alias, add this at the top of your source file:

using Data = System.Double;

Answer 2

No, C# has no direct way of doing that.

You could however wrap that array (and all or most code that uses it) in a generic class:

class MyClass<T>
{
   private T[] Mydata;

}

Answer 3

You can wrap an array of Double in a class and provide index properties for it.

Answer 4

The closest you can get in C# is

using DataEntry = System.Double;

Put this at the top of each file.
