SetBulkData(byte[]) Method

Summary

Sets the BulkData with a byte array.

Syntax

C++/CLI

public void SetBulkData( 
   byte[] byteArray 
)

public:  
   void SetBulkData( 
      array<Byte>^ byteArray 
   )

Parameters

byteArray

a byte array representing the BulkData

Remarks

There are four ways to modify the BulkData:

Setting the BulkData property
Calling [SetBulkData(byte[])] with a byte array
Calling SetBulkData(RasterImage,int) with a RasterImage and a quality factor
Calling SetBulkData(Stream) with Stream
