可以定义一个 static class, 再定义一个静态的字段或者属性就可以了,

 

  

Code Snippet

     public static class CommonData
        {
            private static int data = 0;

            public static int Data
            {
                get { return data; }
                set { data = value; }
            }
        }

 

 

可以这样引用：CommonData.Data

 

也可以定义一个 Singleton 的类, 公开一些字段或者属性.

    

Code Snippet

    public sealed class CommonData
        {
            private int data;
            private static CommonData instance = new CommonData();

            private CommonData() { }

            public static CommonData Instance
            {
                get { return instance; }
                set { instance = value; }
            }

            public int Data
            {
                get { return data; }
                set { data = value; }
            }
        }
