如何为 System.String^ 定义类型别名

Question

I´m trying to define my own type aliases as follows:

using PrjString = System.String;
using PrjInt = System.Int32;
using PrjFloat = System.Single;
using PrjDateTime = System.DateTime;

I´m facing problems with the String type. When I try to use the string and pass it as reference:

PrjString^ name;
GetName(name); // Receives name as reference and return the gathered name

I cannot compile:

PrjString ^name: error CS0118: `string` is a `type` but is used like a `variable`

On the other hand, If I define:

using PrjString = System.String^; 

It does not compile as well:

using PrjString = System.String^: error CS1002: ; expected

Is there a way to define a type alias for System.String^ ?

The ^ notation is not valid syntax in c#. To pass by reference, use the ref keyword:

using PrjString = System.String;

PrjString name;
GetName(ref name);
