问题描述

如何在.idl文件中使用STL类型?例如如果我尝试使用stringstream作为方法的输入参数的类型，则会收到错误MIDL2025 : syntax error expecting a type specification near ''stringstream''

How to use STL types inside .idl file? e.g. If i try to use stringstream as type of input parameter of method, I get error MIDL2025 : syntax error expecting a type specification near ''stringstream''

推荐答案

，您不会将其放在IDL文件中.看一下这个MSDN示例，该示例演示如何将STL类型与ATL一起使用:

You don''t put that in the IDL file. Take a look at this MSDN example that shows how to use STL types with ATL:

http://msdn.microsoft.com/en-us/library/3stwxh95(v=VS.100).aspx[^]

总之，你不能.您可以使用STL等来实现COM公开的方法，但是这些方法本身只能接受某些类型的参数.请参见此处 [

In short, you can''t. You can use STL and such to implement COM exposed methods but the methods themselves can only accept certain types as parameters. See here[^] for a list and details. COM is language neutral so it wouldn''t make sense to export C++ specific types.
