示例1: Open
private FileStream Open(string path, FileMode mode, FileAccess access, FileShare share)
{
// Future: Support System.IO.FileOptions which is the dwFlagsAndAttribute parameter.
var fileHandle = NativeMethods.CreateFileTransactedW(path,
access.ToNative(),
share.ToNative(),
IntPtr.Zero,
mode.ToNative(),
0, IntPtr.Zero,
_TransactionHandle,
IntPtr.Zero, IntPtr.Zero);
var error = Marshal.GetLastWin32Error();
if (fileHandle.IsInvalid)
{
var baseStr = string.Format("Transaction \"{1}\": Unable to open a file descriptor to \"{0}\".", path,
Name ?? "[no name]");
if (error == TxFCodes.ERROR_TRANSACTIONAL_CONFLICT)
throw new TransactionalConflictException(baseStr
+
" You will get this error if you are accessing the transacted file from a non-transacted API before the transaction has "
+ "committed. See HelperLink for details.",
new Uri("http://msdn.microsoft.com/en-us/library/aa365536%28VS.85%29.aspx"));
throw new TransactionException(baseStr + "Please see the inner exceptions for details.",

}
return new FileStream(fileHandle, access);
}示例2: GetFileHandle
private static SafeFileHandle GetFileHandle(string normalizedPath, FileMode mode, FileAccess access, FileShare share,
FileOptions options)
{
var handle = NativeMethods.CreateFile(normalizedPath, access.ToNative(), share.ToNative(), IntPtr.Zero,
mode.ToNative(),

if (handle.IsInvalid)
throw LongPathCommon.GetExceptionFromLastWin32Error();
return handle;
