TCustomMemoryStream.SaveToFile

Writes the contents of the stream to a file.

Declaration

Source position: classesh.inc line 1206

public 
  procedure SaveToFile(const FileName: string);

Description

SaveToFile writes the contents of the stream to a file with name FileName. It simply creates a filestream and writes the contents of the memorystream to this file stream using TCustomMemoryStream.SaveToStream .

This method will work much faster than the use of the TStream.CopyFrom method:

Stream:=TFileStream.Create(fmCreate,FileName);
  Seek(0,soFromBeginning);
  Stream.CopyFrom(Self,Size);

because the CopyFrom method copies the contents in blocks, while SaveToFile writes the contents of the memory as one big block.

!!!

Errors

If an error occurs when creating or writing to the file, an EStreamError exception may occur.
