我需要在运行从 textbox1 获得的字符串输入流程图时创建。表单大小为 700*450，并且允许滚动。每个字母之间（输入字符串中的字符）必须是（在输出中）一个箭头（显示在按钮上）*整个图表必须在按钮 * 例如，对于这个输入字符串：'ABZAZAZA' 每个字母都有一个合适的颜色，按钮的背景应该被着色。

程序应该是“打印”：A --> B --> Z --> A --> Z --> A --> Z --> A -->

箭头按钮尺寸：34*23 字母按钮尺寸：34*29

我的代码的问题，没有显示流程图

继承人的代码：

    public void DrawingSystem(string st)
    {
        shura_acid = 12;
        tur_acid = 185;

        for (int i = 1; i <= st.Length; i++)
        {
            if ((i % 7) == 0)
            {
                OpenNewLine();
            }
            CreateAcid(st[i - 1], i);
            shura_acid = shura_acid + 24 + 68;
        }
    }

    public void OpenNewLine()
    {
        tur_acid = tur_acid + 29 + 12;//34 because the size of button,12 because space between lines
        shura_acid = 12;
    }

    public void CreateAcid(char letter, int i)
    {
        //create acid
        Button acid = new Button();
        acid.Location = new System.Drawing.Point(shura_acid, tur_acid);
        acid.Name = "acid" + i;
        acid.Size = new System.Drawing.Size(34, 29);
        acid.TabIndex = 100 + i;
        acid.Text = Convert.ToString(letter);
        switch (letter)
        {
            case 'A': acid.BackColor = System.Drawing.Color.Fuchsia; break;
            case 'C': acid.BackColor = System.Drawing.Color.Pink; break;
            case 'D': acid.BackColor = System.Drawing.Color.Gray; break;
            case 'F': acid.BackColor = System.Drawing.Color.Azure; break;
            case 'G': acid.BackColor = System.Drawing.Color.Red; break;
            case 'H': acid.BackColor = System.Drawing.Color.Aqua; break;
            case 'I': acid.BackColor = System.Drawing.Color.Lime; break;
            case 'K': acid.BackColor = System.Drawing.Color.Yellow; break;
            case 'L': acid.BackColor = System.Drawing.Color.Olive; break;
            case 'M': acid.BackColor = System.Drawing.Color.Coral; break;
            case 'N': acid.BackColor = System.Drawing.Color.SaddleBrown; break;
            case 'P': acid.BackColor = System.Drawing.Color.Teal; break;
            case 'Q': acid.BackColor = System.Drawing.Color.Blue; break;
            case 'R': acid.BackColor = System.Drawing.Color.Orange; break;
            case 'S': acid.BackColor = System.Drawing.Color.Green; break;
            case 'T': acid.BackColor = System.Drawing.Color.SteelBlue; break;
            case 'V': acid.BackColor = System.Drawing.Color.DarkViolet; break;
            case 'W': acid.BackColor = System.Drawing.Color.Crimson; break;
            case 'X': acid.BackColor = System.Drawing.Color.MediumAquamarine; break;
            default: acid.BackColor = System.Drawing.Color.Gold; break;
        }


        //create arrow
        Button arrow = new System.Windows.Forms.Button();
        arrow.Location = new System.Drawing.Point(shura_acid + 34 + 12, tur_acid);
        arrow.Name = "acid" + i;
        arrow.Size = new System.Drawing.Size(34, 23);
        arrow.TabIndex = 100 + i;
        arrow.Text = "-->";
        arrow.UseVisualStyleBackColor = false;


    }

我会试一试。在您的代码中，我没有看到您实际上将acidorarrow按钮添加到容器中。

你需要这样的东西：

this.Controls.Add(acid);

和

this.Controls.Add(arrow);

更改this.Controls为您希望它们出现的容器。
