CloseFilesAfterReading Property (DicomGlobal)

In This Topic

Controls how pixel data is read from disk

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Shared Property CloseFilesAfterReading As Boolean

'Usage
 
Dim value As Boolean
 
DicomGlobal.CloseFilesAfterReading = value
 
value = DicomGlobal.CloseFilesAfterReading

public static bool CloseFilesAfterReading {get; set;}

public:
static property bool CloseFilesAfterReading {
   bool get();
   void set (    bool value);
}

Remarks

If true, then all the pixel data is read from the disk at the time of reading the file, and the file is then closed. if false, then the file is kept open and pixel data is only read as and when required.

The default setting is true which improves memory usage, but has the downside that the file is locked. If you wish to over-write files which have been opened, then set this value to true before reading the files.

The default value is false

This corresponds to the old "DisableMemoryMapping" registry setting.

If required, this behaviour can be controlled on a file by file basis by using the CloseFilesAfterReading property of the ReadBehaviours class, combined with the appropriate override of DicomDataSet.Read

Requirements

Target Platforms: .NET CLR 4.0 or higher
