IDebugExpressionEvaluator2:: SetCorPath
Imposta il percorso del Common Language (CLR) Runtime caricato nel debugger.
HRESULT SetCorPath(
LPCOLESTR pcstrCorPath
);
int SetCorPath(
string pcstrCorPath
);
Parametri
- pcstrCorPath
[in] Percorso a CLR caricato nel debugger.
Valore restituito
Se l'operazione riesce, restituisce S_OK; in caso contrario, restituisce un codice di errore.
