    public _Public_MyNode()
    {
        ThisMyNode.Add( new MyNode( "数字", 100, "" ) );
        ThisMyNode.Add( new MyNode( "字符", 100, "" ) );
    }
    
    }
    
}
结果只能输出个2.应该输出 “数字”和“字符”的

注意这一行
strNodeType = str_NodeType;

Answer 3

先给strNodeName赋值了,紧接着又赋值为"",哈哈,低级错误
接分~

Answer 4

 // 构造函数
        public MyNode( string str_NodeName, int n_NodeWidth, string str_NodeType )
        {
           strNodeName = str_NodeName;
           nNodeWidth  = n_NodeWidth;
           strNodeName = str_NodeType;//strNodeType = str_NodeType; 
        }

Answer 5

        public MyNode( string str_NodeName, int n_NodeWidth, string str_NodeType )
        {
           strNodeName = str_NodeName;
           nNodeWidth  = n_NodeWidth;
           strNodeName = str_NodeType;
        }

Answer 6

 public MyNode( string str_NodeName, int n_NodeWidth, string str_NodeType )
        {
           strNodeName = str_NodeName;
           nNodeWidth  = n_NodeWidth;
           strNodeType = str_NodeType; 
        }
