C#里判断文件和文件夹是否存在

//判断文件是否存在时用FileInfo或File
string SkinName = Application.StartupPath + "\\skin.txt";

FileInfo myDir = new FileInfo(SkinName);

if (myDir.Exists)
{

}

//判断目录是否存在时用Directory或DirectoryInfo
string SkinName = Application.StartupPath + "\\skin";

DirectoryInfo myDir = new DirectoryInfo(SkinName);

if (myDir.Exists)
{

}
