方法 1
StringToHGlobalAnsi 将托管 String 对象的内容复制到本机堆,然后动态地将它转换为美国国家标准学会 (ANSI) 格式。此方法将分配所需的本机堆内存:
//using namespace System::Runtime::InteropServices; char* str2 = (char*)(void*)Marshal::StringToHGlobalAnsi(str); printf(str2); Marshal::FreeHGlobal( IntPtr(str2) );
方法2
VC7 CString 类有一个构造函数,它带有一个托管 String 指针并将其内容加载到 CString 中:
//#include <atlstr.h> System::String ^ str = "Hello world\n"; CString str3( str ); printf(str3);
--------------------------------------- char * 转 String^ ------------------------
const char * p = "你妹的"; String ^ MyStr = Marshal::PtrToStringAnsi((IntPtr)(char *)p); Console::WriteLine(MyStr);
完整代码示例
//compiler option:cl /clr #include <vcclr.h> #include <atlstr.h> #include <stdio.h> #using <mscorlib.dll> using namespace System; using namespace System::Runtime::InteropServices; int _tmain(void) { System::String ^str = "Hello world\n"; //method 1 char* str2 = (char*)(void*)Marshal::StringToHGlobalAnsi(str); printf(str2); Marshal::FreeHGlobal( IntPtr(str2) );
//method 2 CString str3(str); printf(str3);
const char * p = "你妹的"; String ^ MyStr = Marshal::PtrToStringAnsi((IntPtr)(char *)p); Console::WriteLine(MyStr);return 0;}
