示例1: Main
//引入命名空间
using System;
using System.Threading;
using System.Security.AccessControl;
using System.Security.Principal;
public class Example
{
public static void Main()
{
// Create a string representing the current user.
string user = Environment.UserDomainName + "\\" +

// Create a security object that grants no access.
SemaphoreSecurity mSec = new SemaphoreSecurity();
// Add a rule that grants the current user the
// right to enter or release the semaphore.
SemaphoreAccessRule rule = new SemaphoreAccessRule(user,
SemaphoreRights.Synchronize | SemaphoreRights.Modify,

// Add a rule that denies the current user the
// right to change permissions on the semaphore.
rule = new SemaphoreAccessRule(user,
SemaphoreRights.ChangePermissions,
AccessControlType.Deny);
mSec.AddAccessRule(rule);
// Display the rules in the security object.

// Add a rule that allows the current user the
// right to read permissions on the semaphore. This rule
// is merged with the existing Allow rule.
