如何通过点击按钮动态生成图片框

我正在尝试将pictureboxes动态添加到C#win32表单中，以用于我正在尝试构建的接近生产质量的应用程序，我已经把它搞定了。

我遇到的问题是，我似乎无法在一个方法中动态地向表单添加图片框或控件。我已经通过Form1初始化方法将它们添加到表单中，但如果我在button_click方法中添加控件，它就不会添加它们，除非我有一个面板容器，并键入panel1.controls.add（stuff）。但是，然后picturebox出现在与预期完全不同的位置，并且显然被面板本身阻止了。图片框的大部分被面板挡住了，还有一部分在面板外面。我不知道发生了什么事。

以下是我在网上学习的添加图片框的代码，使用点击按钮的方法：

PictureBox pb = new PictureBox();
        pb.Size = new Size(this.Size.Width / 14, this.Size.Width / 12);  //I use this picturebox simply to debug and see if I can create a single picturebox, and that way I can tell if something goes wrong with my array of pictureboxes. Thus far however, neither are working.
        pb.BackgroundImage = Properties.Resources.cardback;
        pb.BackgroundImageLayout = ImageLayout.Stretch;
        pb.Location = new Point(50, 50);
        pb.Anchor = AnchorStyles.Left;
        pb.Visible = true;
        InitializeComponent();
        this.Controls.Add(pb);
        PictureBox[] pbName = new PictureBox[totaldeckcount];
        for (int i = 0; i < totaldeckcount; i++)
        {
            pbName[i] = new PictureBox();
            pbName[i].Size = new Size(this.Size.Width / 14, this.Size.Width / 12);
            pbName[i].BackgroundImage = Properties.Resources.cardback;
            pbName[i].BackgroundImageLayout = ImageLayout.Stretch;
            pbName[i].Image = Properties.Resources.cardback;
            pbName[i].Anchor = AnchorStyles.Left;
            pbName[i].Visible = true;
            int x = 0;
            int y = 15;
            if (i > 10)
            {
                y += (int)((this.Size.Height * i) + 30);
            }
            x = (int)((this.Size.Width / 12) * Math.IEEERemainder(i, 10));
            pbName[i].Location = new Point(x, y);
            this.Controls.Add(pbName[i]);
        }

Cardback是一种工作纹理，当我尝试用Form1的方法制作图片框时，我看到它会弹出，所以这不是问题所在。问题似乎不是我的语法，因为我可以复制

PictureBox pb = new PictureBox();

代码直接转换到Form1方法中，它执行得很好。

我在谷歌上找不到任何东西，这让我完全不知所措。

   PictureBox[] pics = new PictureBox[50];
    TextBox[] txts = new TextBox[50];
    Button[] butns = new Button[50];
    FlowLayoutPanel[] flws = new FlowLayoutPanel[50]
    static int brh =0; 

    for (int i = 0; i < totalnumbers; i++)
        {
            flws[i] = new FlowLayoutPanel();
            flws[i].Name = "flw" + i;
            flws[i].Location = new Point(3,brh);
            flws[i].Size = new Size(317,122);
            flws[i].BackColor = Color.DarkCyan;
            flws[i].BorderStyle = BorderStyle.Fixed3D;
            flws[i].Disposed += Form1_Disposed;               
            flws[i].Click += new EventHandler(butns_Click);
            pics[i] = new PictureBox();
            pics[i].Location = new Point(953, 95 + brh);
            pics[i].Name = "pic" + i;
            pics[i].Size = new Size(300, 75);
            pics[i].ImageLocation = "E:/image"+i;
            flws[i].Controls.Add(pics[i]);
            txts[i] = new TextBox();
            txts[i].Name = "txt" + i;
            txts[i].Location = new Point(953, 186 + brh);
            txts[i].TextChanged += Form1_TextChanged;
            flws[i].Controls.Add(txts[i]);
            butns[i] = new Button();
            butns[i].Click += new EventHandler(butns_Click);
            butns[i].Text = "submit";
            butns[i].Name = "but" + i;
            butns[i].Location = new Point(1100, 186 + brh);
            flws[i].Controls.Add(butns[i]);
            this.Controls.Add(flws[i]);
            flowLayoutPanel1.Controls.Add(flws[i]);
            brh += 130;
        }  

 private void butns_Click(object sender, EventArgs e)
    {
        // you can add the procces to perform after dynamically created button pressed
     }
