/// 读取注册表键值
/// </summary>
public static string ReadRegistryKey(string name)
{
Microsoft.Win32.RegistryKey reg = Microsoft.Win32.Registry.CurrentUser;
string path="Software\\" + Application.ProductName; if (reg.OpenSubKey(path) == null)
reg.CreateSubKey(path); reg = reg.OpenSubKey(path, true); string str;
if (reg.GetValue(name) == null)
str="";
else
    str = reg.GetValue(name).ToString(); reg.Close();
return str;
}/// <summary>
/// 设置注册表键值
/// </summary>
public static void SetRegistryKey(string name, string Value)
{
Microsoft.Win32.RegistryKey reg = Microsoft.Win32.Registry.CurrentUser;
string path="Software\\" + Application.ProductName; if (reg.OpenSubKey(path) == null)
reg.CreateSubKey(path); reg=reg.OpenSubKey(path,true); reg.SetValue(name, Value);
reg.Close();
}好用就把分都给我吧

using System;
using Microsoft.Win32;public class Example
{
    public static void Main()
    {
        // Delete and recreate the test key.
        Registry.CurrentUser.DeleteSubKey("RegistrySetValueExample", false);
        RegistryKey rk = Registry.CurrentUser.CreateSubKey("RegistrySetValueExample");        // Create name/value pairs.        // Numeric values that cannot be interpreted as DWord (int) values
        // are stored as strings.
        rk.SetValue("LargeNumberValue1", (long) 42);
        rk.SetValue("LargeNumberValue2", 42000000000);        rk.SetValue("DWordValue", 42);
        rk.SetValue("MultipleStringValue", new string[] {"One", "Two", "Three"});
        rk.SetValue("BinaryValue", new byte[] {10, 43, 44, 45, 14, 255});        // This overload of SetValue does not support expanding strings. Use
        // the overload that allows you to specify RegistryValueKind.
        rk.SetValue("StringValue", "The path is %PATH%");
        // Display all name/value pairs stored in the test key, with each
        // registry data type in parentheses.
        //
        string[] valueNames = rk.GetValueNames();
        foreach (string s in valueNames)
        {
            RegistryValueKind rvk = rk.GetValueKind(s);
            switch (rvk)
            {
                case RegistryValueKind.MultiString :
                    string[] values = (string[]) rk.GetValue(s);
                    Console.Write("\r\n {0} ({1}) = \"{2}\"", s, rvk, values[0]);
                    for (int i = 1; i < values.Length; i++)
                    {
                        Console.Write(", \"{0}\"", values[i]);
                    }
                    Console.WriteLine();
                    break;
                
                case RegistryValueKind.Binary :
                    byte[] bytes = (byte[]) rk.GetValue(s);
                    Console.Write("\r\n {0} ({1}) = {2:X2}", s, rvk, bytes[0]);
                    for (int i = 1; i < bytes.Length; i++)
                    {
                        // Display each byte as two hexadecimal digits.
                        Console.Write(" {0:X2}", bytes[i]);
                    }
                    Console.WriteLine();
                    break;
                
                default :
                    Console.WriteLine("\r\n {0} ({1}) = {2}", s, rvk, rk.GetValue(s));
                    break;
            }
        }
    }

Answer 4

//写注册表
RegistryKey regWrite;
//往HKEY_CURRENT_USER主键里的Software子键下写一个名为“Test”的子键
//如果Test子键已经存在系统会自动覆盖它
regWrite = Registry.CurrentUser.CreateSubKey("Software\\Test");
//往Test子键里添两条数据项，一条名为"Name",另一条名为"Sex"
//值分别是"luolie","男"
regWrite.SetValue("Name","luolie");
regWrite.SetValue("Sex","男");
//关闭该对象
regWrite.Close();
读注册表
RegistryKey regRead;
//读取HKEY_CURRENT_USER主键里的Software子键下名为“Test”的子键
regRead= Registry.CurrentUser.OpenSubKey("Software\\Test",true);
if(regRead==null) //如果该子键不存在
{
MessageBox.Show("No Data!")；
}
else
｛
         object obj= regRead.GetValue("Name");  //读取“Name”项的值
         textBox1.Text = obj.ToString();       //显示在TextBox里
｝
//关闭该对象
oReg.Close();
