Write Method
[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]
Writes a block of bytes to the file stream.
Namespace: System.IO
Assembly: System.IO (in System.IO.dll)
Syntax
'Declaration
Public Overrides Sub Write ( _
buffer As Byte(), _
offset As Integer, _
count As Integer _
)
public override void Write(
byte[] buffer,
int offset,
int count
)
public:
virtual void Write(
array<unsigned char>^ buffer,
int offset,
int count
) override
abstract Write :
buffer:byte[] *
offset:int *
count:int -> unit
override Write :
buffer:byte[] *
offset:int *
count:int -> unit
public override function Write(
buffer : byte[],
offset : int,
count : int
)
Parameters
- buffer
Type: array<System. . :: . .Byte> [] () [] []
The buffer containing data to write to the stream.
- offset
Type: System. . :: . .Int32
The zero-based byte offset in buffer from which to begin copying bytes to the stream.
- count
Type: System. . :: . .Int32
The maximum number of bytes to write.
Remarks
This method overrides Write.
The offset parameter gives the offset of the byte in buffer (the buffer index) at which to begin copying, and the count parameter gives the number of bytes that will be written to the stream. If the write operation is successful, the current position of the stream is advanced by the number of bytes written. If an exception occurs, the current position of the stream is unchanged.
Note
Use the CanWrite property to determine whether the current instance supports writing. For additional information, see CanWrite.
Do not interrupt a thread that is performing a write operation. Although the application may appear to run successfully after the thread is unblocked, the interruption can decrease your application's performance and reliability.
