System::String 转 std下的string

[zh2208]

System::String 转 std下的string
String* str = "dd";
string str2 = "";
如何把str中的"dd"赋值到str2中？？

[真相重于对错]

String* str = "dd";
string str2 = reinterpret_cast<char*>(System::Runtime::InteropServices::Marshal::StringToCoTaskMemAnsi(str).ToPointer());

[biweilun]

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

真是感谢！帮我一大忙！

C/C++ code

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