Variant变量可以在COM/DCOM接口方法中传递（传入、传出）不定长结构数组，但是需要打包和解包，效率比较低。这个例子使用了size_is指定长度的方法，本是从MSDN上看到的，但是MSDN上给出的例子不够具体，所以费了些时间摸索，最后试通，给刚接触COM的朋友分享（老家伙们可以直接无视）。本例子由于是工作需要做得试验程序，因此其中存在少量冗余代码，大家注意一下就行了，还有，减少传递的参数个数时，所传递的实时（随机模拟）数据只是减了最后一个（没有减去相对应的），这个Bug不妨碍大局，因此存留，虽然Server支持DCOM，但是Client需要在本地运行，如果想Remote，稍微修改一下既可。-Variant variables can be in the COM/DCOM interface method of delivery (incoming, outgoing) variable-length array of structures, but it needs to be packaged reconciliation package, the efficiency is relatively low. This example uses the method size_is specified length, this is seen from the MSDN, but the example given on MSDN is not specific enough, it took some time to explore, the final test pass, to a friend new to COM sharing (the old guy They can ignore). This example needs to be done because it is the work of testing procedures, and therefore, there is a small amount of redundant code, we take note of the line, and also to reduce the number of parameters passed when the transmission
