Question

private void opc(object sender, EventArgs e)
{
    //NOTE: buttons 13-16 share same click event

    // needs for each loop 
    button13.Enabled = false;
    button14.Enabled = false;
    button15.Enabled = false;
    button16.Enabled = false;
}

Answer 1

你可以试试这个。

private void opc(object sender, EventArgs e)
{
    for (int i = 13; i <= 16; i++)
    {
        Control[] buttons = this.Controls.Find(String.Format("button{0}", i), false);
        if (buttons.Length > 0)
        {
            Button btn = (buttons[0] as Button);
            btn.Click += btn_Click;
            btn.Enabled = true; // or false
        }
    }
}


void btn_Click(object sender, EventArgs e)
{
    MessageBox.Show((sender as Button).Name);
}

见下面的代码：

using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.button13.Click += new System.EventHandler(this.button_Click);
            this.button14.Click += new System.EventHandler(this.button_Click);
            this.button15.Click += new System.EventHandler(this.button_Click);
            this.button16.Click += new System.EventHandler(this.button_Click);
        }

        private void button_Click(object sender, EventArgs e)
        {
            Button button = sender as Button;
            string name = button.Text;
        }
    }
}

您想将assignmens放入循环中吗？使用静态定义的按钮名称是不可能的AFAIK。您应该首先将按钮放入数组或集合中：

Button[] button = new Button[numberOfButtons];
for (int i=0; i<numberOfButtons; i++)
{
    button[i] = new Button();
    button[i].Click += new System.EventHandler(WhateverYouLike);
    // ... some other property assignments, probably also rule-based
}

// ... and at a later time:

for (int i=0; i<numberOfButtons; i++) button[i].Enabled = false;

foreach循环C＃Windows窗体，相同的按钮单击事件
