Methods| Name | Description | |
|---|---|---|
| AreInsideSameBoundary |
Determines whether the range between two specified positions does not cross a structural boundary (e.g. a block boundary on the DFS).
|
| BeginRead | Begins an asynchronous read operation. (Consider using ReadAsync(Byte, Int32, Int32) instead.) (Inherited from Stream.) |
| BeginWrite | Begins an asynchronous write operation. (Consider using WriteAsync(Byte, Int32, Int32) instead.) (Inherited from Stream.) |
| Close | Closes the current stream and releases any resources (such as sockets and file handles) associated with the current stream. Instead of calling this method, ensure that the stream is properly disposed. (Inherited from Stream.) |
| CopyTo(Stream) | Reads the bytes from the current stream and writes them to another stream. (Inherited from Stream.) |
| CopyTo(Stream, Int32) | Reads the bytes from the current stream and writes them to another stream, using a specified buffer size. (Inherited from Stream.) |
| CopyToAsync(Stream) | Asynchronously reads the bytes from the current stream and writes them to another stream. (Inherited from Stream.) |
| CopyToAsync(Stream, Int32) | Asynchronously reads the bytes from the current stream and writes them to another stream, using a specified buffer size. (Inherited from Stream.) |
| CopyToAsync(Stream, CancellationToken) | Asynchronously reads the bytes from the current stream and writes them to another stream, using a specified cancellation token. (Inherited from Stream.) |
| CopyToAsync(Stream, Int32, CancellationToken) | Asynchronously reads the bytes from the current stream and writes them to another stream, using a specified buffer size and cancellation token. (Inherited from Stream.) |
 | CreateWaitHandle | Obsolete. Allocates a WaitHandle object. (Inherited from Stream.) |
| Dispose | Releases all resources used by the Stream. (Inherited from Stream.) |
| Dispose(Boolean) |
Releases the unmanaged resources used by the DfsInputStream and optionally releases the managed resources.
(Overrides StreamDispose(Boolean).) |
| DisposeAsync | Asynchronously releases the unmanaged resources used by the Stream. (Inherited from Stream.) |
| EndRead | Waits for the pending asynchronous read to complete. (Consider using ReadAsync(Byte, Int32, Int32) instead.) (Inherited from Stream.) |
| EndWrite | Ends an asynchronous write operation. (Consider using WriteAsync(Byte, Int32, Int32) instead.) (Inherited from Stream.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize |
Ensures that resources are freed and other cleanup operations are performed when the garbage collector reclaims the DfsInputStream.
(Overrides ObjectFinalize.) |
| Flush |
This method is not used for this class; it does nothing.
(Overrides StreamFlush.) |
| FlushAsync | Asynchronously clears all buffers for this stream and causes any buffered data to be written to the underlying device. (Inherited from Stream.) |
| FlushAsync(CancellationToken) | Asynchronously clears all buffers for this stream, causes any buffered data to be written to the underlying device, and monitors cancellation requests. (Inherited from Stream.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetLifetimeService | Obsolete. Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| InitializeLifetimeService | Obsolete. Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
| ObjectInvariant | Obsolete. Provides support for a Contract. (Inherited from Stream.) |
| OffsetFromBoundary |
Determines the offset of the specified position from the directly preceding structural boundary (e.g. a block boundary on the DFS).
|
| Read(SpanByte) | When overridden in a derived class, reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read. (Inherited from Stream.) |
| Read(Byte, Int32, Int32) |
Reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read.
(Overrides StreamRead(Byte, Int32, Int32).) |
| ReadAsync(MemoryByte, CancellationToken) | Asynchronously reads a sequence of bytes from the current stream, advances the position within the stream by the number of bytes read, and monitors cancellation requests. (Inherited from Stream.) |
| ReadAsync(Byte, Int32, Int32) | Asynchronously reads a sequence of bytes from the current stream and advances the position within the stream by the number of bytes read. (Inherited from Stream.) |
| ReadAsync(Byte, Int32, Int32, CancellationToken) | Asynchronously reads a sequence of bytes from the current stream, advances the position within the stream by the number of bytes read, and monitors cancellation requests. (Inherited from Stream.) |
| ReadByte | Reads a byte from the stream and advances the position within the stream by one byte, or returns -1 if at the end of the stream. (Inherited from Stream.) |
| Seek |
Sets the position within the current stream.
(Overrides StreamSeek(Int64, SeekOrigin).) |
| SetLength |
Not supported.
(Overrides StreamSetLength(Int64).) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Write(ReadOnlySpanByte) | When overridden in a derived class, writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written. (Inherited from Stream.) |
| Write(Byte, Int32, Int32) |
Not supported.
(Overrides StreamWrite(Byte, Int32, Int32).) |
| WriteAsync(ReadOnlyMemoryByte, CancellationToken) | Asynchronously writes a sequence of bytes to the current stream, advances the current position within this stream by the number of bytes written, and monitors cancellation requests. (Inherited from Stream.) |
| WriteAsync(Byte, Int32, Int32) | Asynchronously writes a sequence of bytes to the current stream and advances the current position within this stream by the number of bytes written. (Inherited from Stream.) |
| WriteAsync(Byte, Int32, Int32, CancellationToken) | Asynchronously writes a sequence of bytes to the current stream, advances the current position within this stream by the number of bytes written, and monitors cancellation requests. (Inherited from Stream.) |
| WriteByte | Writes a byte to the current position in the stream and advances the position within the stream by one byte. (Inherited from Stream.) |
