public class FileStream : Stream
The FileStream type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Close | Closes the current stream and releases any resources (such as sockets and file handles) associated with the current stream. (Inherited from Stream.) |
| CopyTo(Stream) | Reads the bytes from the current stream and writes them to the destination stream. (Inherited from Stream.) |
| CopyTo(Stream, Int32) | Reads all the bytes from the current stream and writes them to a destination stream, using a specified buffer size. (Inherited from Stream.) |
| Dispose | Releases all resources used by the Stream. (Inherited from Stream.) |
 | Dispose(Boolean) | Releases the unmanaged resources used by the Stream and optionally releases the managed resources. (Inherited from Stream.) |
| Equals(Object) | (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Read | 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.) |
| 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 | When overridden in a derived class, sets the position within the current stream. (Inherited from Stream.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Write | 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.) |
| WriteByte | Writes a byte to the current position in the stream and advances the position within the stream by one byte. (Inherited from Stream.) |
Properties| Name | Description | |
|---|---|---|
 | CanRead | When overridden in a derived class, gets a value indicating whether the current stream supports reading. (Inherited from Stream.) |
| CanSeek | When overridden in a derived class, gets a value indicating whether the current stream supports seeking. (Inherited from Stream.) |
| Length | When overridden in a derived class, gets the length in bytes of the stream. (Inherited from Stream.) |
| Name | Gets the name of the FileStream that was passed to the constructor. |
| Position | When overridden in a derived class, gets or sets the position within the current stream. (Inherited from Stream.) |
