Access vector from C#

[Reza Shademani]

Hello, I want to access my native functionalities from an unmanaged dll which performs my core processings. clinet program will be written by C# and i use DLLImport attribute to mix managed and native codes. How could i pass STL vector params between C# and C++? If there is no robust method of doing this, what's the remedy to send and receive array like data between C# and C++?

A vector is an array internally ( that is, it's continuous memory ). Therefore, if you set up an equivelant class in C# ( assuming it's not just a simple type ), you should be able to pass it through.

No. (Assuming you want to retain the full integrity of the vector, vs. just the data.) For examples on how to pass arrays of data, look at P/Invoke.
