1、添加下拉框的值：

comboBoxEdit1.Properties.Items.Add("12");

2、获取选中下拉框的值：

控件事件SelectedIndexChanged下，添加comboBoxEdit1.SelectedIndex.ToString();

3、获取选中下拉框的值：

comboBoxEdit1.Properties.Items\[comboBoxEdit1.SelectedIndex\].ToString();

完整代码示例和结果如下：

using System;
    using System.Collections.Generic;
    using System.ComponentModel;
    using System.Data;
    using System.Drawing;
    using System.Linq;
    using System.Text;
    using System.Windows.Forms;
    
    namespace ComboBoxEdit
    {
        public partial class Form1 : Form
        {
            public Form1()
            {
                InitializeComponent();
                Init();
            }
    
            private void Init()
            {
                comboBoxEdit1.Properties.Items.Add("12");//添加下拉框的值
                comboBoxEdit1.Properties.Items.Add("13");
                comboBoxEdit1.Properties.Items.Add("14");
                comboBoxEdit1.Properties.Items.Add("15");
            }
    
            private void comboBoxEdit1_SelectedIndexChanged(object sender, EventArgs e)
            {
                string str;
                //str = comboBoxEdit1.Properties.Items[comboBoxEdit1.SelectedIndex].ToString();//获取选中值的值
                str = comboBoxEdit1.SelectedIndex.ToString();//获取选中值的索引值
                textEdit1.Text = str;
            }
        }
    }
