C# 什么'；在c语言中，使用不同的按钮执行重复操作的最佳方法是什么#

这是我当前的代码：

        subject subject1;
    string DocPath = AppDomain.CurrentDomain.BaseDirectory  + "Documents/";
    public Form1()
    {
        InitializeComponent();
        subject1 = new subject();                     
    }
    public class subject
    {
        Form1 frm;

        public void changeTab(int tabPage/* , Form1 frm1 */, Form1 frm1)
        {
            frm = frm1;
            frm.TabControlSubjects.SelectTab(tabPage);
        }

    }

    private void materialRaisedButton1_Click(object sender, EventArgs e)
    {

        subject1.changeTab(0, this);        
    }

    private void materialRaisedButton2_Click(object sender, EventArgs e)
    {
        subject1.changeTab(1, this);
    }

    private void materialRaisedButton4_Click(object sender, EventArgs e)
    {
        subject1.changeTab(2, this);
    }

    private void materialRaisedButton3_Click(object sender, EventArgs e)
    {
        subject1.changeTab(3, this);
    }

    private void materialRaisedButton8_Click(object sender, EventArgs e)
    {
        subject1.changeTab(4, this);
    }

    private void materialRaisedButton7_Click(object sender, EventArgs e)
    {
        subject1.changeTab(5, this);
    }

    private void materialRaisedButton6_Click(object sender, EventArgs e)
    {
        subject1.changeTab(6, this);
    }

    private void materialRaisedButton5_Click(object sender, EventArgs e)
    {
        subject1.changeTab(7, this);
    }

    private void materialRaisedButton12_Click(object sender, EventArgs e)
    {
        subject1.changeTab(8, this);
    }

    private void materialRaisedButton11_Click(object sender, EventArgs e)
    {
        subject1.changeTab(9, this);
    }

    private void materialRaisedButton10_Click(object sender, EventArgs e)
    {
        subject1.changeTab(10, this);
    }

    private void materialRaisedButton9_Click(object sender, EventArgs e)
    {
        subject1.changeTab(11, this);
    }

有没有更有效的方法？因为如果我现在看的话，似乎有更好的方法。我是C#的新手，说话的时候还在学习。欢迎提供任何建议/提示。

谢谢阅读。

试试这个。我从按钮的文本名称中提取按钮的编号

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 WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        subject subject1;
        string DocPath = AppDomain.CurrentDomain.BaseDirectory + "Documents/";
        public Form1()
        {
            InitializeComponent();
            subject1 = new subject();
            materialRaisedButton1.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton2.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton3.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton4.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton5.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton6.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton7.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton8.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton9.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton10.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton11.Click += new EventHandler(materialRaisedButton_Click);
            materialRaisedButton12.Click += new EventHandler(materialRaisedButton_Click);
        }
        public class subject
        {
            Form1 frm;

            public void changeTab(int tabPage/* , Form1 frm1 */, Form1 frm1)
            {
                frm = frm1;
                frm.TabControlSubjects.SelectTab(tabPage);
            }

        }
        const string buttonPrefix = "materialRaisedButton";
        private void materialRaisedButton_Click(object sender, EventArgs e)
        {
            Button button = sender as Button;
            string name = button.Text;
            int number = int.Parse(name.Substring(buttonPrefix.Length));

            subject1.changeTab(number, this);
        }

    }

}​

是的，将所有按钮映射到同一个单击事件，并执行一些逻辑以获得所需的整数。谢谢！但最后一件事，你能给我解释一下

as

在

Button-Button=sender-as-Button中的作用吗？只需将发送者强制转换为按钮对象。
