1.主窗体下的代码

namespace TestReflection
    {
        public partial class Form2 : Form
        {
            public Form2()
            {
                InitializeComponent();
            }
    
            /// <summary>
            /// 赋值属性
            /// </summary>
            /// <param name="sender"></param>
            /// <param name="e"></param>
            private void simpleButton1_Click(object sender, EventArgs e)
            {
                Attribute.School = "金陵中学";
                Attribute.Class = "高一6班";
                Attribute.Name = "奚学长";
                Attribute.Sex = "男";
                Attribute.Age = "17";
            }
    
            /// <summary>
            /// 显示属性
            /// </summary>
            /// <param name="sender"></param>
            /// <param name="e"></param>
            private void simpleButton2_Click(object sender, EventArgs e)
            {
                List<string> listAttribute = new List<string> { "School", "Class", "Name", "Sex", "Age" };
                try
                {
                    foreach (string item in listAttribute)
                    {
                        listBoxControl1.Items.Add(ShowAttribute(item));
                    }
                }
                catch
                { 
                
                }
            }
    
            /// <summary>
            /// 传入属性名 来获取属性
            /// </summary>
            /// <param name="Name">属性名</param>
            /// <returns></returns>
            private string ShowAttribute(string Name)
            {
                try
                {
                        typeof(类名)
                    Type type = typeof(Attribute);
    
                        根据属性名，获取类下的属性
                    PropertyInfo p = type.GetProperty(Name);
    
                        获得属性值
                    object obj = p.GetValue(null, null);
                    
                    if (obj != null)
                    {
                        return obj.ToString();
                    }
                    else
                    {
                        return "Null";
                    }
                }
                catch
                {
                    return "Null";
                }
    
            }
        }
    }

2.属性

namespace TestReflection
    {
        class Attribute
        {
            public static string School
            {
                get;
                set;
            }
    
            public static string Class
            {
                get;
                set;
            }
    
            public static string Name
            {
                get;
                set;
            }
    
            public static string Sex
            {
                get;
                set;
            }
    
            public static string Age
            {
                get;
                set;
            }
        }
    }
