vb.net 如何通过byref 将结构传递给线程? [英] vb.net how to pass structure to thread by byref?

问题描述

当我尝试将结构引用传递到线程时出现构建错误.

I get a build error when I try to pass a structure reference into a thread.

dim antenna_frame_buffer as Antenna_Frame_Buffer_structure
...

new_buffer_write_thread = new Thread( AddressOf frame_buffer_write_Thread )
new_buffer_write_thread.Start( antenna_frame_buffer )   

...

    sub frame_buffer_write_Thread( ByRef antenna_frame_buffer as Antenna_Frame_Buffer_structure ) 
...

错误...

推荐答案

结构不能通过引用传递给线程.然而，幸运的是，类的对象可以通过引用传递.

Structure cannot be passed by reference to a thread. However, and fortunately, an object of a class CAN be passed by reference.
