示例1: Main
//引入命名空间
using System;
using Microsoft.Win32;
using Microsoft.VisualBasic;
public class Example
{
public static void Main()
{
// Delete and recreate the test key.
Registry.CurrentUser.DeleteSubKey("RegistryValueOptionsExample", false);
RegistryKey rk =
Registry.CurrentUser.CreateSubKey("RegistryValueOptionsExample");
// Add a value that contains an environment variable.
rk.SetValue("ExpandValue", "The path is %PATH%", RegistryValueKind.ExpandString);
// Retrieve the value, first without expanding the environment
// variable and then expanding it.
Console.WriteLine("Unexpanded: \"{0}\"",
rk.GetValue("ExpandValue", "No Value",
RegistryValueOptions.DoNotExpandEnvironmentNames));
Console.WriteLine("Expanded: \"{0}\"", rk.GetValue("ExpandValue"));
} //Main
} //Example示例2: Main
//引入命名空间
using System;
using Microsoft.Win32;
public class Example
{
public static void Main()
{
// Delete and recreate the test key.
Registry.CurrentUser.DeleteSubKey("RegistryValueKindExample", false);
RegistryKey rk = Registry.CurrentUser.CreateSubKey("RegistryValueKindExample");
// Create name/value pairs.
// This overload supports QWord (long) values.
rk.SetValue("QuadWordValue", 42, RegistryValueKind.QWord);
// The following SetValue calls have the same effect as using the
// SetValue overload that does not specify RegistryValueKind.
//
rk.SetValue("DWordValue", 42, RegistryValueKind.DWord);
rk.SetValue("MultipleStringValue", new string[] {"One", "Two", "Three"}, RegistryValueKind.MultiString);
rk.SetValue("BinaryValue", new byte[] {10, 43, 44, 45, 14, 255}, RegistryValueKind.Binary);
rk.SetValue("StringValue", "The path is %PATH%", RegistryValueKind.String);
// This overload supports setting expandable string values. Compare
// the output from this value with the previous string value.
rk.SetValue("ExpandedStringValue", "The path is %PATH%", RegistryValueKind.ExpandString);
// Display all name/value pairs stored in the test key, with each
// registry data type in parentheses.
//
