先通过实验观察不同平台目标组件的下拉列表。在Visual Studio中依序调整PlatformTarget为Any CPU, x86及x64，分别编译成EventPingPongAny.exe, EventPingPongX86.exe, EventPingPongX64.exe三个程序集。

再使用corflags EventPingPong*.exe的方法检查相关属性，得到结果如下:

H:\Lab\EventPingPong\bin>corflags EventPingPongAny.exe

若要将编译成Any CPU的程序目标平台改为限定x86，可使用以下指令:

CorFlags /32BIT+ EventPingPongAny.exe

将参数改为/32BIT-则可以再还原回Any CPU。至于纯x64目标平台的程序由于PE不同(为PE32+，与Any CPU, x86不同)，故无法直接使用CorFlags切换，必须重新编译。
