OpenFileWriteStream Method (path, fileSize, lastWriteTime)

Microsoft Deployment Tools

Deployment Tools Foundation OpenFileWriteStream Method (path, fileSize, lastWriteTime)

Opens a stream for writing extracted file bytes.

Declaration Syntax

Visual Basic

Visual C++

public virtual Stream OpenFileWriteStream(
	string path,
	long fileSize,
	DateTime lastWriteTime
)

Public Overridable Function OpenFileWriteStream ( _
	path As String, _
	fileSize As Long, _
	lastWriteTime As DateTime _
) As Stream

public:
virtual Stream^ OpenFileWriteStream(
	String^ path, 
	long long fileSize, 
	DateTime lastWriteTime
)

Parameters

path (String): The path of the file within the archive.

fileSize (Int64): The uncompressed size of the file to be extracted.

lastWriteTime (DateTime): The last write time of the file to be extracted.

Return Value

A stream where extracted file bytes are to be written, or null to skip extraction of the file and continue to the next file.

Remarks

This method opens a file using the following logic: If the Directory and the Files mapping are both null, the path is treated as relative to the current directory, and that file is opened.If the Directory is not null but the Files mapping is null, the path is treated as relative to that directory, and that file is opened.If the Directory is null but the Files mapping is not null, the path parameter is used as a key into the mapping, and the resulting value is the file path that is opened, relative to the current directory (or it may be an absolute path). If no mapping exists, the file is skipped.If both the Directory and the Files mapping are specified, the path parameter is used as a key into the mapping, and the resulting value is the file path that is opened, relative to the specified directory (or it may be an absolute path). If no mapping exists, the file is skipped.

If the ExtractOnlyNewerFiles flag is set, the file is skipped if a file currently exists in the same path with an equal or newer write time.
