C#根据数据生成力引导图

本文主要是介绍C#根据数据生成力引导图，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

效果：

    public class Rootobject
    {
        public Node[] nodes { get; set; }
        public Link[] links { get; set; }
        public Category[] categories { get; set; }
    }

    /// <summary>
    /// 节点
    /// </summary>
    public class Node
    {
        public string id { get; set; }
        public string name { get; set; }
        public float symbolSize { get; set; }

        public float value { get; set; }
        public int category { get; set; }
    }

    /// <summary>
    /// 关联
    /// </summary>
    public class Link
    {
        public string source { get; set; }
        public string target { get; set; }
    }

    /// <summary>
    /// 分类
    /// </summary>
    public class Category
    {
        public string name { get; set; }
    }

            #region 分类
            for (int i = 0; i < lines.Length; i++)

                string[] valueNum = lines[i].Split('#');
