Namespace: System.IO
Assembly: System.IO (in System.IO.dll)
Syntax
'Declaration
Public Overrides Sub SetLength ( _
value As Long _
)
public override void SetLength(
long value
)
public:
virtual void SetLength(
long long value
) override
abstract SetLength :

public override function SetLength(
value : long

Parameters
- value
Type: System. . :: . .Int64
The new length of the stream.
Remarks
If the given value is less than the current length of the stream, the stream is truncated. If the given value is larger than the current length of the stream, the stream is expanded. If the stream is expanded, the contents of the stream between the old and the new length are undefined.
A stream must support both writing and seeking for SetLength to work.
Note
Use the CanWrite property to determine whether the current instance supports writing, and the CanSeek property to determine whether seeking is supported. For additional information, see CanWrite and CanSeek.
