如何检查2个DirectoryInfo对象是否指向同一目录？

DirectoryInfo directory1 = new DirectoryInfo("path1");
DirectoryInfo directory2 = new DirectoryInfo("path2");

if (directory1.FullName == directory2.FullName)
{
    Console.WriteLine("两个 DirectoryInfo 对象指向同一目录");
}
else
{
    Console.WriteLine("两个 DirectoryInfo 对象指向不同的目录");
}
