C#:如何检查是否可以读取和/或删除目录

string directoryPath = @"C:\example\directory";
if (Directory.Exists(directoryPath))
{
    try
    {
        string[] files = Directory.GetFiles(directoryPath);
        Console.WriteLine("Directory can be read.");
    }
    catch (UnauthorizedAccessException)
    {
        Console.WriteLine("Directory cannot be read.");
    }
}
else
{
    Console.WriteLine("Directory does not exist.");
}

string directoryPath = @"C:\example\directory";
if (Directory.Exists(directoryPath))
{
    try
    {
        Directory.Delete(directoryPath);
        Console.WriteLine("Directory can be deleted.");
    }
    catch (UnauthorizedAccessException)
    {
        Console.WriteLine("Directory cannot be deleted.");
    }
}
else
{
    Console.WriteLine("Directory does not exist.");
}
