C# 注册右键菜单、文件夹与文件的实现代码

本文介绍的代码，显示了如何通过操作注册表，添加文件或文件夹右键菜单的方法。

代码如下：

// 添加到注册表
private void btnRegister_Click(object sender, EventArgs e)
{
if (this.tbMenuTitle.Text.Length == 0) return;

// 注册到文件
if (this.ckRegToFile.checked)
{
RegistryKey shell = Registry.ClassesRoot.OpenSubKey("*", true).OpenSubKey("shell", true);
if (shell == null) shell = Registry.ClassesRoot.OpenSubKey("*", true).CreateSubKey("shell");
RegistryKey custome = shell.CreateSubKey(this.tbMenuTitle.Text);
RegistryKey cmd = custome.CreateSubKey("command");
cmd.SetValue("", Application.ExecutablePath + " %1");
cmd.Close();
custome.Close();
shell.Close();
}

// 注册到文件夹 www.jb200.com
if (this.ckRegToDir.Checked)
{
RegistryKey shell = Registry.ClassesRoot.OpenSubKey("directory", true).OpenSubKey("shell", true);
if (shell == null) shell = Registry.ClassesRoot.OpenSubKey("directory", true).CreateSubKey("shell");
RegistryKey custome = shell.CreateSubKey(this.tbMenuTitle.Text);
RegistryKey cmd = custome.CreateSubKey("command");
cmd.SetValue("", Application.ExecutablePath + " %1");
cmd.Close();
custome.Close();
shell.Close();
}
MessageBox.Show("注册成功!", "提示");
}

// 反注册
private void btnUnRegister_Click(object sender, EventArgs e)
{
RegistryKey shell = Registry.ClassesRoot.OpenSubKey("*", true).OpenSubKey("shell", true);
if (shell != null) shell.DeleteSubKeyTree(this.tbMenuTitle.Text);

shell = Registry.ClassesRoot.OpenSubKey("directory", true).OpenSubKey("shell", true);
if (shell != null) shell.DeleteSubKeyTree(this.tbMenuTitle.Text);

shell.Close();

MessageBox.Show("反注册成功!", "提示");
}
