Reset Method (DicomDir)

Show in webframe
Example 







The name of an existing destination folder in which to save the DICOMDIR File.
Removes the contents of the Directory and reinitializes it.
Syntax
public void Reset( 
   string destinationFolder
)
'Declaration
 
Public Sub Reset( _
   ByVal destinationFolder As String _
) 
'Usage
 
Dim instance As DicomDir
Dim destinationFolder As String
 
instance.Reset(destinationFolder)
public void Reset( 
   string destinationFolder
)

            

            
 function Leadtools.Dicom.DicomDir.Reset( 
   destinationFolder 
)
public:
void Reset( 
   String^ destinationFolder
) 

Parameters

destinationFolder
The name of an existing destination folder in which to save the DICOMDIR File.
Remarks
When an object of the DicomDir class is created, the DICOM Directory, as specified by the object, is empty. To revert to this case at any time, call the method Reset. If the same object is to be used to create the DICOM Directory of a new file-set, this method must be called first.

This method also sets the destination folder of the DICOMDIR File. Please note that although the method can be passed a null reference (Nothing in Visual Basic), no DICOM file can be added to the DICOM Directory unless this folder is specified.
