VB.NET如何遍历注册表键

这篇文章给大家分享的是有关VB.NET如何遍历注册表键的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。

VB.NET遍历注册表代码如下：

Imports Microsoft.Win32  Public Class Form1  Dim KeyUsers As RegistryKey  ''' 
 ''' 显示用户列表  ''' summary> ''' 显示用户的列表对象param> ''' remarks> Private Sub ListAllUsers(ByVal list As ListBox)  '清除列表中的内容  list.Items.Clear()  '遍历用户键下的子键  For Each keyname As String In KeyUsers.GetSubKeyNames()  list.Items.Add(keyname)  Next  End Sub  ''' 
 ''' 判断用户是否存在  ''' summary> ''' 用户名param> ''' 存在返回true，否则返回falsereturns> ''' remarks> Private Function IsUserExists(ByVal username As String) As Boolean  '遍历用户键下的子键  For Each keyname As String In KeyUsers.GetSubKeyNames()  '如果用户存在返回true  If (keyname.ToUpper() = username.ToUpper()) Then  Return True  End If  Next  Return False  End Function   ''' 
 ''' 删除用户  ''' summary> ''' 被删除的用户名param> ''' remarks> Private Sub DeleteUser(ByVal username As String)  If (IsUserExists(username)) Then  '删除该用户对应的键  KeyUsers.DeleteSubKey(username)  ListAllUsers(ListBox1)  End If  End Sub  '更多vb.net源代码和实例，请关注乐博网lob.cn  ''' 
 ''' 添加用户  ''' summary> ''' 用户名param> ''' 添加成功返回true，否则返回falsereturns> ''' remarks> Private Function AddUser(ByVal username As String) As Boolean  Try  '判断用户是否存在  If (IsUserExists(username)) Then  MsgBox("用户已经存在，请输入其它用户！")  Return False  End If  '创建用户键  KeyUsers.CreateSubKey(username, _  RegistryKeyPermissionCheck.ReadWriteSubTree)  '重新列表  ListAllUsers(ListBox1)  Catch ex As Exception  Return False  End Try  End Function  Private Sub btnCreateKey_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCreateKey.Click  Dim key As RegistryKey  Dim mykey As RegistryKey  '首先需要获得HKEY_CURRENT_USER\Softwar子键，将writable设置为True确保可写  key = My.Computer.Registry.CurrentUser.OpenSubKey("Software", True)  '在HKEY_CURRENT_USER\Softwar下面创建子键并返回创建的子键对象  mykey = key.CreateSubKey("MyKey", RegistryKeyPermissionCheck.ReadWriteSubTree)  '创建值并且设置值的内容  mykey.SetValue("UserName", "Rui.Chen", RegistryValueKind.String)  End Sub  Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged  If (ListBox1.SelectedIndex >= 0) Then  btnDelete.Enabled = True Else  btnDelete.Enabled = False End If  End Sub  Private Sub btnDelete_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click  DeleteUser(ListBox1.SelectedItem.ToString())  End Sub  Private Sub btnCreate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCreate.Click  If (TextBox1.Text <> "") Then  AddUser(TextBox1.Text)  End If  End Sub  Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load  KeyUsers = My.Computer.Registry.CurrentUser.OpenSubKey("Software\MyKey", True)  ListAllUsers(ListBox1)  btnDelete.Enabled = False End Sub  End Class
