如何检查C#中的某个目录是否有权限访问？

using System;
using System.IO;

class Program
{
    static void Main()
    {
        string directoryPath = "C:\\path\\to\\directory";

        DirectoryInfo directoryInfo = new DirectoryInfo(directoryPath);

        if (directoryInfo.Exists)
        {
            try
            {
                // 检查目录是否可读
                bool isReadable = CheckDirectoryReadAccess(directoryInfo);

                // 检查目录是否可写
                bool isWritable = CheckDirectoryWriteAccess(directoryInfo);

                // 检查目录是否可执行
                bool isExecutable = CheckDirectoryExecuteAccess(directoryInfo);

                Console.WriteLine($"目录是否可读：{isReadable}");
                Console.WriteLine($"目录是否可写：{isWritable}");
                Console.WriteLine($"目录是否可执行：{isExecutable}");
            }
            catch (UnauthorizedAccessException)
            {
                Console.WriteLine("没有访问目录的权限");
            }
        }
        else
        {
            Console.WriteLine("目录不存在");
        }
    }

    static bool CheckDirectoryReadAccess(DirectoryInfo directoryInfo)
    {
        try
        {
            // 尝试打开目录以检查读取权限
            directoryInfo.GetFiles();
            return true;
        }
        catch (UnauthorizedAccessException)
        {
            return false;
        }
    }

    static bool CheckDirectoryWriteAccess(DirectoryInfo directoryInfo)
    {
        try
        {
            // 尝试在目录中创建一个临时文件以检查写入权限
            string tempFilePath = Path.Combine(directoryInfo.FullName, Guid.NewGuid().ToString());
            using (File.Create(tempFilePath)) { }
            File.Delete(tempFilePath);
            return true;
        }
        catch (UnauthorizedAccessException)
        {
            return false;
        }
    }

    static bool CheckDirectoryExecuteAccess(DirectoryInfo directoryInfo)
    {
        try
        {
            // 尝试获取目录的父目录以检查执行权限
            DirectoryInfo parentDirectory = directoryInfo.Parent;
            return parentDirectory != null;
        }
        catch (UnauthorizedAccessException)
        {
            return false;
        }
    }
}
