Question

我有一个Windows窗体应用程序，我正在尝试添加按钮来模仿计算器。

public class myform : Form
{
    public myform()
    {
        //setting size of form
        this.Text = "Calculator";
        this.Height = 600;
        this.Width = 400;

        //creating buttons from 0-9
        Button[] b = new Button[10];
        int x = 0;
        int y = 0;
        string ch;
        for (int i = 0; i < b.Length; i++)
        {
            ch = Convert.ToString(i);
            x = 0;
            y = y + 50;
            b[i] = new Button();
            b[i].Height = 40;
            b[i].Width = 40;
            b[i].Text = ch;
            for (int j = 0; j < 3; j++)
            {
                x = x + 50;
                b[i].Location = new Point(x, y);
            }
        }

        for (int i = 0; i < b.Length; i++)
        {
            this.Controls.Add(b[i]);
        }

    }
}

这里是我正在创建上述myform类对象的表单类。

public partial class Form1 : Form
{
    public Form1()
    {

        InitializeComponent();
        myform mf = new myform();
        mf.Show();
    }
}

问题似乎是你总是将x值设置为x = x + 150;我建议你把你的x值改为x =（i％3）* 50;你的y到y =（i / 3）* 50; 应该为你提供一系列漂亮的按钮。

        ch = Convert.ToString(i);
        x = (i%3)*50;
        y = (i/3)*50;
        b[i] = new Button();
        b[i].Height = 40;
        b[i].Width = 40;
        b[i].Text = ch;
        b[i].Location = new Point(x, y);

将是你的新循环体。
