WebString Pool. A string pool is a specialized memory pool that attempts to efficiently manage and mitigate some of the more expensive operations required when utilizing strings in an application. This could include, but is not limited to, decreasing the cost of dynamic allocation, memory usage, and comparison operations. WebNext the StringBuilder object is passed to the C++ code and its default marshalling is as a LPWSTR. In this approach the C# code allocates the string and your C++ code receives a C string to which it must copy the buffer. Alternatively you can return a BSTR from the C++ which allows allocation in the native C++ code and deallocation in the C# code.
