System::String 转 std下的string
System::String 转 std下的string
String* str = "dd";
string str2 = "";
如何把str中的"dd"赋值到str2中？？
[解决办法]
String* str = "dd";
string str2 = reinterpret_cast<char*>(System::Runtime::InteropServices::Marshal::StringToCoTaskMemAnsi(str).ToPointer());
[解决办法]

std::string ConvertToString(System::String^ str)
{
 int q=(int)System::Runtime::InteropServices::Marshal::StringToHGlobalAnsi(str);
 char* p=(char*)q;
 return std::string(p);
}
