VFileStream Constructor

Namespace: Rebex.IO

Assembly: Rebex.FileSystem.dll (version 7.0.9147)

VFileStream(String, FileMode, FileAccess, FileShare, Int32, Boolean)

Initializes a new instance of the VFileStream for a file identified by the path, required mode and requested access. A caller must dispose the returned stream. Arguments share, bufferSize and useAsync are not used.

Declaration

public VFileStream(string path, FileMode mode, FileAccess access, FileShare share, int bufferSize, bool useAsync)

Parameters

Type	Name	Description
String	path	The path of the file.
FileMode	mode	One of the FileMode values which determines how to open a file.
FileAccess	access	One of the FileAccess values which determines if the returned stream should be read-only stream, write-only stream or read/write stream.
FileShare	share	This argument is ignored. Concurrent access to the same virtual file is not supported and leads to undefined behavior.
Int32	bufferSize	This argument is ignored.
Boolean	useAsync	This argument is ignored. Rebex virtual file systems now supports only synchronous methods.

Remarks

Concurrent access to the same virtual file is not supported and leads to undefined behavior.

Examples

//Create a built-in or custom VFS provider 
var memoryProvider = new MemoryFileSystemProvider()
//Save the root path
var memoryProviderRootPath = memoryProvider.GetRootVDirectoryInfo().FullName;
//Create 'file.dat' file in the root directory and open VFileStream for writing.
using (var myFileStream = new VFileStream(Path.Combine(memoryProviderRootPath, "file.dat"), FileMode.CreateNew, FileAccess.Write))
{
    myFileStream.Write(myData, 0, myData.Length);
}

Parameters

Type	Name	Description
