摘　　要：OPC数据存取规范基于COM,要将其移植到.NET平台,需要解决编排过程中数据类型转换、接口实现、参数传递等问题。研究C#接口属性类.、NET托管和非托管的转换后,解决了OPC数据存取规范3.0定制接口COM编排的问题。OPC data access specification is based on COM,the problem such as the data type transform,interface implementation,argument pass must be handled when it migrate to . NET planfform. The problem of COM marshalling OPC data access specification version 3.0 is solved after the C# attributes class of interface and the transfrom of. NET managed and unmanaged have been studied.
