ReadOnlyFileSystemProvider.GetContent Method

Namespace: Rebex.IO.FileSystem

Assembly: Rebex.FileSystem.dll (version 7.0.9147)

GetContent(NodeBase, NodeContentParameters)

Override this method to implement retrieval of the content for the node.

By default, this method is only called for files (instances of the class FileNode). To enable this method for directories (instances of DirectoryNode), add a new instance of FileSystemProviderSettings (with the property EnableGetContentMethodForDirectories set to true) to the ReadOnlyFileSystemProvider(FileSystemProviderSettings) constructor.

When the virtual file system is used in the FileServer component, the server session, which contains information about the user and the active connection, can be accessed using Current property.

Parameters

Examples

protected override NodeContent GetContent(NodeBase node, NodeContentParams contentRequest)
{
 var fullPath = getFullPath(node.Path);
 if (contentRequest.AccesType == NodeContentAccess.Read)
 {
   var readOnlyStream = File.OpenRead(fullPath);
   return NodeContent.CreateReadOnlyContent(readOnlyStream);
 }

 var realFsAccessMode = contentRequest.AccesType == NodeContentAccess.Write
   ? FileAccess.Write
   : FileAccess.ReadWrite;

 var readWriteStream = File.Open(fullPath, FileMode.Open, realFsAccessMode);
 return NodeContent.CreateImmediateWriteContent(readWriteStream);
