使用VS连接Oracle时，提示： "Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed"

环境：VS2015       Oracle 11g 64位   Oracle客户端版本 32位

连接时提示问题：

"Attempt to load Oracle client libraries threw BadImageFormatException. This problem will occur when running in 64 bit mode with the 32 bit Oracle client components installed"  

解决办法：在环境变量Path中添加"C:\Oracle\product\instantclient_12_1\NETWORK\ADMIN;“实际依个人安装情况而定，主要是欺骗VS，使其认为Oracle是32位的

原理不是很清楚，后补
