以编程方式创建ToolStrip按钮 [英] Programmatically create ToolStrip buttons

问题描述

我正在尝试根据文件夹的内容创建工具条按钮，到目前为止，我是这样的:

//Collect list of files<br />
            string dir = "C:\\Documents and Settings\\Herr Xandor\\Desktop\\Toolbar";<br />
            string[] files = System.IO.Directory.GetFiles(dir);<br />
            //Format string array<br />
            int x = 0;<br />
            int index = 0;<br />
            foreach (string temp in files)<br />
            {<br />
                index = temp.LastIndexOf(''\\'');<br />
                files[x] = temp.Substring(index + 1);<br />
                x += 1;<br />
            }<br />

我的问题是，如何基于数组的内容创建按钮.我知道我需要另一个foreach循环，该循环为每个按钮运行必要的命令，但是如何控制命名和onClick方法?我不知道如何使用变量来命名对象.我很确定我可以通过使用按钮数组来创建按钮，但是该如何创建事件处理程序呢?

解决方案

此 [ string[] files = System.IO.Directory.GetFiles(dir);<br /> //Format string array<br /> int x = 0;<br /> int index = 0;<br /> foreach (string temp in files)<br /> {<br /> index = temp.LastIndexOf(''\\'');<br /> files[x] = temp.Substring(index + 1);<br /> x += 1;<br /> }<br />

My question is, how can I create buttons based on the contents of the array. I understand that I need another foreach loop that runs the necessary commands for each button but how can I control the naming and the onClick methods? I know of no way to use a variable to name an object. I''m pretty sure I can get it to create the buttons by using an array of buttons, but then how can I create the event handlers?

解决方案

using System;
using System.IO;
using System.Windows.Forms;
namespace DynamicToolStrip
{
    static class Program
    {
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new DynamicToolStripForm());
        }
        class DynamicToolStripForm : Form
        {
            ToolStrip m_toolstrip = new ToolStrip();
            public DynamicToolStripForm()
            {
                Controls.Add(m_toolstrip);
                AddToolStripButtons();
            }
            void AddToolStripButtons()
            {
                const int iMAX_FILES = 5;
                string[] astrFiles = Directory.GetFiles(@"C:\");
                for (int i = 0; i < iMAX_FILES; i++)
                {
                    string strFile = astrFiles[i];
                    ToolStripButton tsb = new ToolStripButton();
                    tsb.Text = Path.GetFileName(strFile);
                    tsb.Tag = strFile;
                    tsb.Click += new EventHandler(tsb_Click);
                    m_toolstrip.Items.Add(tsb);
                }
            }
            void tsb_Click(object sender, EventArgs e)
            {
                ToolStripButton tsb = sender as ToolStripButton;
                if (tsb != null && tsb.Tag != null)
                    MessageBox.Show(String.Format("Hello im the {0} button", tsb.Tag.ToString()));
            }
        }
    }
}
