推荐答案

1-选择所有按钮，然后转到属性选项卡
2-选择事件图标.
3- on Click事件下拉列表旁边的并选择包含操作的方法

1- select all buttons then go to property tab
2- select event icon.
3- on Click event drop down the list beside and select the method that contains the action

您可以在类似这样的函数中获取按钮的文本

You can get the Text of button in the function like this

 private void OnPress(object sender, System.EventArgs e)
        {
            ((Button)sender).Text; // to get Text inside

//((Button)sender).Name; to get name
        }

我认为您想要以下内容

I think you want something like following

private void Common_btn_click_event_Click(object sender, EventArgs e)
       {
           Button btn=((Button)sender);
           string btn_text= btn.text;
           if (btn.Text == "Room 1")
           {
                    Frm_Customer _Frm_Customer = new Frm_Customer();
                    _Frm_Customer.refToFrm_Rooms = this;
                    _Frm_Customer.ButtonBase = btn.text;
                    btn_Room1.BackColor = Color.Red;
                    this.Visible = true;
                   _Frm_Customer.Show();
           }
           else if (btn.Text == "Reserved")
           {
                   DialogResult dlgResult = MessageBox.Show("You Have More Time?", "Do You wnat to Vocate?", MessageBoxButtons.YesNo, MessageBoxIcon.Question);
           if (dlgResult == DialogResult.Yes)
           {
           {
                   btn.BackColor = Color.Red;
                   if(btn.Name=="btn_Room1")
                      btn.Text = "Room 1";
                   else if(btn.Name=="btn_Room2")
                      btn.Text = "Room 2";  
                   SqlConnection con = new SqlConnection();
                   string[] conString = DBSettings.connectionStringValues();
                   string connectionString = string.Format(@"server=" + conString[0] + ";database=Restaurant;uid=" + conString[2] + ";pwd=" + conString[3]);
                   con.ConnectionString = connectionString;
                   con.Open();
                   SqlCommand cmd = new SqlCommand("update AllRooms set RunFlag=0 where RoomName='"+ btn.Text +"'", con);
                   SqlDataReader _sqldatareader = cmd.ExecuteReader();
                   _sqldatareader.Read();
                   con.Close();
             }
             }
             else if(dlgResult==DialogResult.No)
             {
             }
           }
       }
