Public Class SqlBlobStream |
The type exposes the following members.
Public Constructors
| Name | Description | |
|---|---|---|
 | SqlBlobStreamSqlBlobStreamNew | Overloaded. |
Public Methods
| Name | Description | |
|---|---|---|
| BeginRead | Begins an asynchronous read operation. (Inherited from Stream.) |
| BeginWrite | Begins an asynchronous write operation. (Inherited from Stream.) |
| Close |
Overridden. Closes the file and releases any resources associated with the current file stream.
(Overrides Stream..::Close()().) |
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
| EndRead | Waits for the pending asynchronous read to complete. (Inherited from Stream.) |
| EndWrite | Ends an asynchronous write operation. (Inherited from Stream.) |
| Equals | (Inherited from Object.) |
| Flush |
Overridden. Clears all buffers for this stream and causes any buffered data to be written to the underlying device.
(Overrides Stream..::Flush()().) |
| GetHashCode | Serves as a hash function for a particular type. GetHashCode()() is suitable for use in hashing algorithms and data structures like a hash table. (Inherited from Object.) |
| GetLifetimeService | 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 | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| Open |
Opens the closed connection.
|
| Read |
Overridden. Reads a block of bytes from the stream and writes the data in a given buffer.
(Overrides Stream..::Read(array<Byte>[](), Int32, Int32).) |
| 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 |
Overridden. Sets the current position of this stream to the given value.
(Overrides Stream..::Seek(Int64, SeekOrigin).) |
| SetLength |
Overridden. Sets the length of this stream to the given value.
(Overrides Stream..::SetLength(Int64).) |
| ToString | (Inherited from Object.) |
| Write |
Overridden. Writes a block of bytes to this stream using data from a buffer.
(Overrides Stream..::Write(array<Byte>[](), Int32, Int32).) |
| WriteByte | Writes a byte to the current position in the stream and advances the position within the stream by one byte. (Inherited from Stream.) |
Protected Methods
| Name | Description | |
|---|---|---|
 | CreateWaitHandle | Obsolete. Allocates a WaitHandle object. (Inherited from Stream.) |
| Dispose |
Releases the resources used by the SqlBlobStream.
(Overrides Stream..::Dispose(Boolean).) |
| Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetDataLength |
Gets the selected element's data length.
|
| GetDataLengthCommand |
Gets the sql command returning Data Length.
|
| GetOpenPointerCommand |
Gets the sql command returning a text pointer.
|
| GetReadTextCommand |
Gets the sql command reading a blob element.
|
| GetUpdateTextCommand |
Gets the sql command updating a blob element.
|
| GetUpdateTextCommandWithNullValue |
Gets the sql command inserting a blob element.
|
| Init |
Initializes a new connection.
|
| MemberwiseClone | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
| OnInit |
Raises the Init event.
|
| OpenPointer |
Opens the text pointer.
|
| ReadText |
Reads the array from the BLOB column.
|
| UpdateText |
Writes the array into the BLOB column.
|
| UpdateTextCommandWithNullValue |
Writes the array into the BLOB column.
|
Public Properties

|
| CanRead |
Overridden. Gets a value indicating whether the current stream supports reading.
(Overrides Stream..::CanRead.) |
| CanSeek |
Overridden. Gets a value indicating whether the current stream supports seeking.
(Overrides Stream..::CanSeek.) |
| CanTimeout | Gets a value that determines whether the current stream can time out. (Inherited from Stream.) |
| CanWrite |
Overridden. Gets a value indicating whether the current stream supports writing.
(Overrides Stream..::CanWrite.) |
| ColumnName |
Gets, sets a table column for the BLOB value that the current SqlBlobStream object will encapsulate.
