作不规则窗体涉及到API的调用和大量的编程，是件很复杂的事情。下面我们可以使用Borland C# Builder轻松的实现一个不规则窗体，以下面用一个示例来讲述其制作过程。
一.准备不规则窗体位图
二.窗体的设置
三.代码的完成

一.准备不规则窗体位图
为了方便起见，我们随便找几个别的软件用的Skin。
这里使用金山影霸 2003的安装目录下的skins\ocean\KingDVD_Disable.BMP
当然完全可以使用画图工具，制作一个有形状的位图，背景使用一种特别的颜色，如白色。这个颜色会在后面用得上。

二.窗体的设置
1.新建C# Application

2.选中新建的窗体，设置其相应属性：
(1).将 FormBorderStyle 属性设置为 None。
(2).将窗体的 BackgroundImage 属性设置为先前面的位图文件。
(3).将 TransparencyKey 属性设置为位图文件的背景色，本例中为白色。（此属性告诉应用程序窗体中的哪些部分需要设置为透明。）
(4).加一个picturebox1，就是一关闭位图，点击时关闭应用程序。
(5).加一个contextMenu1，添加一菜单项“退出”，将winform的contextMenu设为contextMenu1。

按F9运行你的程序，就可以看到你的不规则窗体了。

三.代码的完成
   前面做的窗口还不能移动。加入下面的代码使其能移动起来，帖出完整的示例代码：

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;

   this.pictureBox1.Click += new System.EventHandler(this.pictureBox1_Click);
   //
   // WinForm
   //
   this.AutoScaleBaseSize = new System.Drawing.Size(6, 14);
   this.BackgroundImage = ((System.Drawing.Image)(resources.GetObject("$this.BackgroundImage")));
   this.ClientSize = new System.Drawing.Size(365, 235);
   this.ContextMenu = this.contextMenu1;
   this.Controls.Add(this.pictureBox1);
   this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
   this.MaximizeBox = false;
   this.MinimizeBox = false;
   this.Name = "WinForm";
   this.Text = "WinForm";
   this.TransparencyKey = System.Drawing.Color.White;

   this.MouseMove += new System.Windows.Forms.MouseEventHandler(this.WinForm_MouseMove);
   this.ResumeLayout(false);
  }
  #endregion

  }

  private void WinForm_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)

      int xOffset;
      int yOffset;

      if (e.Button == MouseButtons.Left)

        yOffset = -e.Y - SystemInformation.CaptionHeight -
          SystemInformation.FrameBorderSize.Height;
        mouseOffset = new Point(xOffset, yOffset);
        isMouseDown = true;
      }
  }

  private void WinForm_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
  {
                        // 修改鼠标状态isMouseDown的值
                        // 确保只有鼠标左键按下并移动时，才移动窗体
                        if (e.Button == MouseButtons.Left)
                        {
                                isMouseDown = false;
      }
  }

  private void pictureBox1_Click(object sender, System.EventArgs e)
  {
   this.Close();
  }
}
}

注：如果监视器的颜色深度设置大于 24 位，TransparencyKey 设置成白色，窗体的非透明部分还是会显示出来，不知道为什么。
