c++ cli convert string to string^
To convert a std::string
to System::String^
in C++/CLI, you can follow these steps:
Include the necessary header files:
cpp #include <msclr/marshal_cppstd.h>
Use the
msclr::interop::marshal_as
function to perform the conversion:cpp std::string str = "Hello"; System::String^ managedStr = msclr::interop::marshal_as<System::String^>(str);
Let's break down these steps:
Step 1: Include the necessary header files
The msclr/marshal_cppstd.h
header file provides the necessary functions for marshaling between managed and native types in C++/CLI.
Step 2: Use the msclr::interop::marshal_as
function
The msclr::interop::marshal_as
function is a utility function provided by the C++/CLI library. It is used to convert between different types, such as std::string
and System::String^
. In this case, we pass the std::string
variable str
as the first argument and specify the target type System::String^
as the second template argument. The result of the conversion is stored in the managedStr
variable.
By using these steps, you can successfully convert a std::string
to System::String^
in C++/CLI.
