Sets the length of this stream to the given value.
Assembly: mscorlib (in mscorlib.dll)
This method overrides SetLength.
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.
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.
