Unity 使用this关键字进行函数拓展 - Graphic

Example:

      var image = GetComponent<Image>();
      image
          .SetColor(Color.white)
          .SetColor(1f, 1f, 1f)
          .SetColor(1f, 1f, 1f, 1f)
          .SetColorAlpha(1f)
          .SetMaterial(null)
          .SetRaycastTarget(true);
  
 

Extension:

      using UnityEngine;
      using UnityEngine.UI;
      namespace SK.Framework
      {
         /// <summary>

             public static T SetColor<T>(this T self, Color color) where T : Graphic
