Possible to add properties in an extension class?

Is it possible to add properties or Getter&Setter to an extension?

// Extension
public static class GameObjectExtension
{
public static float x( this GameObject go ) => go.transform.position.x;
public static void SetX( this GameObject go, float n ) =>
go.transform.position = new Vector3( n, go.transform.position.y, go.transform.position.z );
}

// usage:
float posX = objectA.x();
objectB.SetX( posX );

// PREFERED USAGE:
float posX = objectA.x;
objectB.x = posX;

This is showing how to add methods. I want to add properties.

 

I cannot test right now. Can you see if this works?

Code (CSharp):

1. public static float posX { get; set; }

or

Code (CSharp):

1. private static float mPosX;
2.  
3. public static float PosX
4. {
5.   get
6.   {
7.     return mPosX;
8.   }
9.   set
10.   {
11.     mPosX = value;
12.   }
13. }

 

Dude... òO

 

Code (CSharp):

1. public static void SetX(this Transform trans)
2. {
3.   trans.position = new Vector3( posX, trans.position.y, trans.position.z );
4. }

If you cannot pass var through methods.
