You can pass multiples SID at a time to these commands. But you would
have to batch the resolving in your app.

You can write a very simple C wrapper and call the wrapper from C#.
So you would have:
void* init_connection(const char *user, const char *pw)
// establish connection and return handle
const char* name_to_sid(void *con, const char *name)
// use con to resolve and return sid
const char* sid_to_name(void *con, const char *sid)
// use con to resolve and return name
void free_connection(void *con)
// release con handle
This wrapper would link against the same libs as rpcclient binary and
would compile to librpcwrapper.so. From C you can #include all the
struct definitions you need or copy them from the source code.
Then from C# you just load librpcwrapper.so and call those simple functions.
