在vc ++中将'System :: String ^'转换为'const char*'

#include <vcclr.h>
#include<string>
using namespace System;

int main() {
    String^ managedString = "Hello, World!";
    pin_ptr<const wchar_t> wch = PtrToStringChars(managedString);
    std::wstring ws(wch);
    const wchar_t* rawWCharString = ws.c_str();
    return 0;
}
