How would you convert this script:

    var originalWidth = 640.0;
    var originalHeight = 400.0;
    private var scale: Vector3;
    
    function OnGUI(){
    scale.x = Screen.width/originalWidth; // calculate hor scale
    scale.y = Screen.height/originalHeight; // calculate vert scale
    scale.z = 1;
    var svMat = GUI.matrix; // save current matrix
    GUI.matrix = Matrix4x4.TRS(Vector3.zero, Quaternion.identity, scale);
    GUI.Box(Rect(10,10,200,50), "Box");
    GUI.Button(Rect(400,180,230,50), "Button");
    
    GUI.matrix = svMat; // restore matrix
    }

into C#?

Here it is:

public class FileName : MonoBehaviour
{
    public float originalWidth = 640.0f;
	public float originalHeight = 400.0f;
	private Vector3 scale = new Vector3();

	private void OnGUI()
	{
		scale.x = Screen.width / originalWidth; // calculate hor scale
		scale.y = Screen.height / originalHeight; // calculate vert scale
		scale.z = 1;

		var svMat = GUI.matrix; // save current matrix

		GUI.matrix = Matrix4x4.TRS(Vector3.zero, Quaternion.identity, scale);
		GUI.Box(Rect(10,10,200,50), "Box");
		GUI.Button(Rect(400,180,230,50), "Button");
		GUI.matrix = svMat; // restore matrix
	}
}
