C# 指针操作相关

=========================================

// ** 取int 地址以指针访问指向值 ** //

int size = Marshal.SizeOf(typeof(HLC2_OUT_DATA));

int* pInt = &size;

_syslog((*pInt).ToString());

// ** string 与IntPtr互转 ** //

string txt = "abce";

IntPtr pStr = Marshal.StringToCoTaskMemAnsi(txt); //分配内存，将string内容移入

string ss = Marshal.PtrToStringAnsi(pStr);

_syslog(ss);

//释放

Marshal.FreeHGlobal(pStr);

// ** char*与string互转 **/

string a = "11";

char* aChar = (char*)Marshal.StringToCoTaskMemAnsi(a).ToPointer(); //IntPtr To Char*

string s = Marshal.PtrToStringAnsi((IntPtr)aChar); //Char* To IntPtr

_syslog(s);

//** char* 与 IntPtr互转 **/

IntPtr intPtr = (IntPtr)aChar;

char* aChar1 = (char*)intPtr;
