.NET Memory Management Basics .NET memory management is designed so that the programmer is freed from the chore of consciously having to allocate and dispose of memory resources. It is optimized to work best with the most common patters of usage. How
一:什么是IntPtr 先来看看MSDN上说的:用于表示指针或句柄的平台特定类型.这个其实说出了这样两个事实,IntPtr 可以用来表示指针或句柄.它是一个平台特定类型.对于它的解释,这个哥们写的比较好:It's a class that wraps a pointer that is used when calling Windows API functions. The underlying pointer may be 32 bit or 64 bit, depending on the

在解析C#结构体指针前,必须知道C#结构体是如何定义的.在c#中同样定义该结构体. C#结构体指针之C#结构体的定义: [StructLayout(LayoutKind.Sequential)] public struct VGAStat { public int ChannelNum;//通道数量 [MarshalAs(UnmanagedType.ByValArray, SizeConst = 64)] public char[] Version;//版本信息 public uint CPUU
