示例1: EnumerateChildrenInternal
internal static IEnumerable<IFileSystemInformation> EnumerateChildrenInternal(
string directory,
ChildType childType,
string searchPattern,
System.IO.SearchOption searchOption,
FileAttributes excludeAttributes,
IFileService fileService)
{
// We want to be able to see all files as we recurse and open new find handles (that might be over MAX_PATH).
// We've already normalized our base directory.
string extendedDirectory = Paths.AddExtendedPrefix(directory);
// The assertion here is that we want to find files that match the desired pattern in all subdirectories, even if the
// subdirectories themselves don't match the pattern. That requires two passes to avoid overallocating for directories
// with a large number of files.
// First look for items that match the given search pattern in the current directory
using (FindOperation findOperation = new FindOperation(Paths.Combine(extendedDirectory, searchPattern)))
{
FindResult findResult;
while ((findResult = findOperation.GetNextResult()) != null)
{
bool isDirectory = (findResult.Attributes & FileAttributes.FILE_ATTRIBUTE_DIRECTORY) == FileAttributes.FILE_ATTRIBUTE_DIRECTORY;
if ((findResult.Attributes & excludeAttributes) == 0
&& findResult.FileName != "."
&& findResult.FileName != ".."
&& ((isDirectory && childType == ChildType.Directory)
|| (!isDirectory && childType == ChildType.File)))
{
yield return FileSystemInformation.Create(findResult, directory, fileService);
}
}
}
if (searchOption != System.IO.SearchOption.AllDirectories) yield break;
// Now recurse into each subdirectory
using (FindOperation findOperation = new FindOperation(Paths.Combine(extendedDirectory, "*"), directoriesOnly: true))
{
