C# VisualStudio中的多个轨迹栏

我已经使用microsoft的示例代码创建了一个任务栏，但无法使用它创建多个任务栏

这是我正在使用的代码

public class form1
{
    private System.Windows.Forms.TrackBar trackBar1;
    private System.Windows.Forms.TextBox textBox1;
    private System.Windows.Forms.TrackBar trackBar2;
    private System.Windows.Forms.TextBox textBox2;

    public Form1()
    {
        this.textBox1 = new System.Windows.Forms.TextBox();
        this.trackBar1 = new System.Windows.Forms.TrackBar();

        // TextBox for TrackBar.Value update.
        this.textBox1.Location = new System.Drawing.Point(240, 0);
        this.textBox1.Size = new System.Drawing.Size(48, 20);

        // Set up how the form should be displayed and add the controls to the form.
        this.ClientSize = new System.Drawing.Size(296, 62);
        this.Controls.AddRange(new System.Windows.Forms.Control[]
        {
            this.textBox1, this.trackBar1
        });
        this.Text = "TrackBar Example";

        // Set up the TrackBar.
        this.trackBar1.Location = new System.Drawing.Point(0, 0);
        this.trackBar1.Size = new System.Drawing.Size(224, 45);
        trackBar1.Maximum = 255;
        this.textBox2 = new System.Windows.Forms.TextBox();
        this.trackBar2 = new System.Windows.Forms.TrackBar();

        // TextBox for TrackBar.Value update.
        this.textBox2.Location = new System.Drawing.Point(240, 800);
        this.textBox2.Size = new System.Drawing.Size(48, 20);

        // Set up how the form should be displayed and add the controls to the form.
        this.ClientSize = new System.Drawing.Size(296, 62);
        this.Controls.AddRange(new System.Windows.Forms.Control[]
        {
            this.textBox1, this.trackBar1
        });
        this.Text = "TrackBar Example";

        // Set up the TrackBar.
        this.trackBar2.Location = new System.Drawing.Point(0, 100);
        this.trackBar2.Size = new System.Drawing.Size(224, 45);
        trackBar2.Maximum = 255;
    }
}

当我使用trackbar1时，它运行得非常好，当我定义trackbar1和trackbar2时，我只看到trackbar1而没有看到trackbar2。代码没有给出错误

注意：这不是全部代码，只是一个代码片段，您需要进一步放大表单并更改：

   this.Controls.AddRange(new System.Windows.Forms.Control[] { this.textBox1, this.trackBar1 });

到

在轨迹栏中

此外，要查看文本框2，您需要更改

this.textBox2.Location = new System.Drawing.Point(240, 800);

到

这是一个好问题。非常感谢。

this.textBox2.Location = new System.Drawing.Point(240, 800);

this.textBox2.Location = new System.Drawing.Point(240, 100);
