C# 计数按钮'；C中的s颜色#

我的程序有问题。我有3个按钮，默认颜色是白色。当我的按钮背面颜色变为红色时，我的程序将计算有多少按钮是红色的。我有一个使用foreach的想法，但它不起作用

Button[] Tombol = new Button[]{B1, B2, B3}
int counterbutton = 0;

foreach (Button Tombol2.BackColor = Color.Red in Tombol) //I have problem here. I don't know how to solve
{
  counterbutton++;
}

我认为正确的语法是

foreach(Button btn in Tombol)
{
    if(btn.BackColor == Color.Red)
       counterbutton++;
}

试试这个

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
    {
        public Form1()
        {
            InitializeComponent();

            Button[] Tombol = new Button[]{B1, B2, B3};
            int counterbutton = 0;
            B1.BackColor = Color.Red;
            B3.BackColor = Color.Red;

            foreach (Button b in Tombol)
            {
                if(b.BackColor == Color.Red) //I have problem here. I don't know how to solve
                {
                    counterbutton++;
                }
            }
        }
    }
}

linq的一个示例：

var counter = Tombol.Count(b=>b.BackColor == Color.Red)

顺便问一下，

Tombol2

是什么？Tombol2是按钮[]中的所有按钮Tombol:）

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
    {
        public Form1()
        {
            InitializeComponent();

            Button[] Tombol = new Button[]{B1, B2, B3};
            int counterbutton = 0;
            B1.BackColor = Color.Red;
            B3.BackColor = Color.Red;

            foreach (Button b in Tombol)
            {
                if(b.BackColor == Color.Red) //I have problem here. I don't know how to solve
                {
                    counterbutton++;
                }
            }
        }
    }
}

var counter = Tombol.Count(b=>b.BackColor == Color.Red)
