Summary

Enumeration values that represent the processing state.

Syntax

C++

public enum ProcessState

Public Enum ProcessState

public enum class ProcessState

Members

Value	Member	Description
0	Start	The processing of fields has started.
1	Processed	A field has been processed.
2	WillProcess	A field will be processed.
3	Finish	The processing of fields has finished. There are no other fields left to process.

Remarks

ProcessState is used in ProgressEventArgs to show the current state of processing.
