TotalCount Property

Summary

Gets or sets the total count of possible metadata records.

Syntax

C++/CLI

public int TotalCount {get; set;}

public:  
   property Int32 TotalCount 
   { 
      Int32 get() 
      void set(Int32 value) 
   }

Property Value

The total count of possible metadata records

Remarks

The TotalCount is equal to the number of DICOM instances stored in the Instance database table. This is the case because there can be one XML metadata record (or one JSON metadata record) for each DICOM instance.
