C# IntPtr 與 string互轉

一、IntPtr 與 string互轉

string str = "aa";

IntPtr init = Marshal.StringToHGlobalAnsi(str);

string ss= Marshal.PtrToStringAnsi(init);

//最后釋放掉

Marshal.FreeHGlobal(init);  

二、char*與string互轉

 string a = "11";      

 char* aChar = (char*)System.Runtime.InteropServices.Marshal.StringToHGlobalAnsi(a).ToPointer(); 

string result = Marshal.PtrToStringAnsi((IntPtr)aChar);   

三、char* 與 IntPtr互轉

可以直接強制類型轉換

IntPtr init = (IntPtr)aChar;

char* aChar = (char*)init;
