利用反射遍历Enum,并显示在ComboBox上，根据枚举的值，选中在comboBox中指定的项

 1using System;
 2using System.Collections.Generic;
 3using System.ComponentModel;
 4using System.Data;
 5using System.Drawing;
 6using System.Linq;
 7using System.Text;
 8using System.Threading;
 9using System.Windows.Forms;

namespace BrowserDemo
{
    public partial class Form8 : Form
    {
        public Form8()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            DoWork();
        }
        private void DoWork()
        {
            Thread t = new Thread(new ThreadStart(this.DoSomething));
            t.Start();
        }
        private void DoSomething()
        {
            MessageBox.Show("thread start");
        }

        private void button2_Click(object sender, EventArgs e)
        {
            foreach (var v in typeof(AA).GetFields())
            {
                if (v.FieldType.IsEnum == true)
                {
                    this.comboBox1.Items.Add(v.Name);
                }
            }
            this.comboBox1.SelectedIndex = 1;


        }
        public enum AA
        {
            B,
            C
        }

        private void button3_Click(object sender, EventArgs e)
        {

            AA a = AA.B;
            MessageBox.Show(a.ToString());
            this.comboBox1.SelectedIndex = this.comboBox1.FindString(a.ToString());
        }
    }
}

是些小技巧，但每次要用的时候都得google一遍，真的很痛恨自己这一点，怎么记性就不能再好一点，很耽误时间。在这里记录一下吧
