“无法将方法组分配给隐式类型的局部变量” 制作计算器

这里的第二篇文章，所以我最近开始了我的计算课程，我们正在研究 C#，我已经了解了一切，我们有我们的第一个项目，我们应该处理，但是我在这里被难住了，我将向您展示整个代码供您阅读，然后我将在底部脱离到发现错误的部分：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
namespace Calculator
{
public partial class Form1 : Form
{
    string number;
    public Form1()
    {
        InitializeComponent();
    }
    private void textBox1_TextChanged(object sender, EventArgs e)
    {
    }
    private void Form1_Load(object sender, EventArgs e)
    {
    }
    private void Number0_Click(object sender, EventArgs e)
    {
        number = number + "0";
        CalcForm.Text = number;
    }
    private void Number1_Click(object sender, EventArgs e)
    {
        number = number + "1";
        CalcForm.Text = number;
    }
    private void Number2_Click(object sender, EventArgs e)
    {
        number = number + "2";
        CalcForm.Text = number;
    }
    private void Number3_Click(object sender, EventArgs e)
    {
        number = number + "3";
        CalcForm.Text = number;
    }
    private void Number4_Click(object sender, EventArgs e)
    {
        number = number + "4";
        CalcForm.Text = number;
    }
    private void Number5_Click(object sender, EventArgs e)
    {
        number = number + "5";
        CalcForm.Text = number;
    }
    private void Number6_Click(object sender, EventArgs e)
    {
        number = number + "6";
        CalcForm.Text = number;
    }
    private void Number7_Click(object sender, EventArgs e)
    {
        number = number + "7";
        CalcForm.Text = number;
    }
    private void Number8_Click(object sender, EventArgs e)
    {
        number = number + "8";
        CalcForm.Text = number;
    }
    private void Number9_Click(object sender, EventArgs e)
    {
        number = number + "9";
        CalcForm.Text = number;
    }
    private void ButtonDecimal_Click(object sender, EventArgs e)
    {
        number = number + ".";
        CalcForm.Text = number;
    }
    private void ButtonTimes_Click(object sender, EventArgs e)
    {
        string equation1 = CalcForm.Text;
        double equation1int = Convert.ToDouble(equation1);
        CalcForm.Text = "";
        number = "";
        string equation2 = CalcForm.Text;
        double equation2int = Convert.ToDouble(equation2);
        var equalsclicked = ButtonEquals_Click;
        if (equalsclicked == true) 
        {
        CalcForm.Text = "";
        number = "";
        double answer = equation1int * equation2int;
        string answer1 = Convert.ToString(answer);
        CalcForm.Text = answer1;
    }
    }
    private void ButtonEquals_Click(object sender, EventArgs e)
    {
    }
}
}

所以，有表单代码，这是错误，我将在确切的行上发表评论

{
    string equation1 = CalcForm.Text;
    double equation1int = Convert.ToDouble(equation1);
    CalcForm.Text = "";
    number = "";
    string equation2 = CalcForm.Text;
    double equation2int = Convert.ToDouble(equation2);
    var equalsclicked = ButtonEquals_Click; //Here
    if (equalsclicked == true) //Here
    {
    CalcForm.Text = "";
    number = "";
    double answer = equation1int * equation2int;
    string answer1 = Convert.ToString(answer);
    CalcForm.Text = answer1;
}

有错误，你还能看出什么问题吗？还是优化明智？这只是为了乘法，但是一旦我这样做了，我可以轻松地复制它，谢谢:)
