NET 自定义控件 以及 propertyGrid

如果添加 Category， 自定义控件，会放在杂项中

命名空间 system.ComponentModel

public class Model
{
    //   分组
	[Category("通信")]   
	// 描述信息，就是  window中 属性，下面的解释信息。 
	[Description("设置IP地址")]
	public string IP {get;set;}
}

propertyGrid

namespace WindowsFormsApp1
{
    public class StudentModel
    {
        [Category("ZEN")]
        [Description("学生姓名")]
        public string Student_Name { get; set; }
        [Category("ZEN")]
        [Description("喜欢的颜色")]
        public Color Favourite_Color { get; set; }
        private Teacher teacherInfo;
        // 显示下一级
        [TypeConverter(typeof(ExpandableObjectConverter))]
        //可编辑
        [EditorBrowsable(EditorBrowsableState.Always)]
        //描述信息
        [Description("任课老师信息")]
        //分组
        [Category("Teacher信息")]
        public Teacher TeacherInfo {
            get {
                if (teacherInfo ==null)
                {
                    return teacherInfo = new Teacher();
                }else {
                    return teacherInfo;
                }
            }
            set {
                teacherInfo = value;
            }
        }
    }
    public class Teacher
    {
        [Description("英语老师名字")]
        public string EnglishName { get; set; }
        [Description("数学老师名字")]
        public string MathName { get; set; }
        [Description("语文老师名字")]
        public string ChineseName { get; set; }
        public override string ToString()
        {
