CurrentItem Property

Summary

Gets or sets a value that represents the index of the metadata record that has just been generated.

Syntax

C++/CLI

public int CurrentItem {get; set;}

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

Property Value

A value that represents the index of the metadata record that has just been generated.

Remarks

The GenerateMetadataXml and GenerateMetadataJson classes both generate metadata, and fire the following events:

These events all have the GenerateMetadataArgs class as a parameter.
