該類實現了注冊表讀取、寫入、刪除、查找等功能。

實現代碼：

using System; using System.Collections.Generic; using System.Linq; using System.Text; using Microsoft.Win32;namespace TagReceiver {class RegistryHelper{/// <summary>/// 讀取指定名稱的注冊表的值/// </summary>/// <param name="name"></param>/// <returns></returns>public string GetRegistryData(RegistryKey root, string subkey, string name) { string registData = ""; RegistryKey myKey = root.OpenSubKey(subkey, true);if (myKey != null){registData = myKey.GetValue(name).ToString();}return registData; } /// <summary>/// 向注冊表中寫數據/// </summary>/// <param name="name"></param>/// <param name="tovalue"></param> public void SetRegistryData(RegistryKey root, string subkey, string name, string value) { RegistryKey aimdir = root.CreateSubKey(subkey); aimdir.SetValue(name, value); } /// <summary>/// 刪除注冊表中指定的注冊表項/// </summary>/// <param name="name"></param>public void DeleteRegist(RegistryKey root, string subkey, string name) { string[] subkeyNames;RegistryKey myKey = root.OpenSubKey(subkey, true);subkeyNames = myKey.GetSubKeyNames();foreach (string aimKey in subkeyNames) { if(aimKey == name)myKey.DeleteSubKeyTree(name); } } /// <summary>/// 判斷指定注冊表項是否存在/// </summary>/// <param name="name"></param>/// <returns></returns>public bool IsRegistryExist(RegistryKey root, string subkey, string name) { bool _exit = false; string[] subkeyNames; RegistryKey myKey = root.OpenSubKey(subkey, true);subkeyNames = myKey.GetSubKeyNames(); foreach(string keyName in subkeyNames) { if(keyName == name) { _exit = true; return _exit; } } return _exit; } } }

如何調用：

讀注冊表：RegistryHelper rh = new RegistryHelper();string portName = rh.GetRegistryData(Registry.LocalMachine, "SOFTWARE\\TagReceiver\\Params\\SerialPort", "PortName"); 寫注冊表：RegistryHelper rh = new RegistryHelper();rh.SetRegistryData(Registry.LocalMachine, "SOFTWARE\\TagReceiver\\Params\\SerialPort", "PortName", portName);

所有代碼在WinXP SP3+VS2010下測試通過。
