相當(dāng)于序列化與反序列化，但是不用借助外部文件
1、struct轉(zhuǎn)換為byte[]

?1static???byte[]???StructToBytes(object???structObj)???
?2??{???
?3??int???size???=?????Marshal.SizeOf(structObj);???
?4??IntPtr???buffer???=???Marshal.AllocHGlobal(size);???
?5??try???
?6??{???
?7??Marshal.StructureToPtr(structObj,???buffer,???false);???
?8??byte[]???bytes???=???new???byte[size];???
?9??Marshal.Copy(buffer,???bytes,???0,???size);???
10??return???bytes;???
11??}???
12??finally???
13??{???
14??Marshal.FreeHGlobal(buffer);???
15??}???
16????
17??}?

?2、byte[]轉(zhuǎn)換為struct

?1static???object???BytesToStruct(byte[]???bytes,???Type???strcutType)???
?2??{???
?3??int???size???=?????Marshal.SizeOf(strcutType);???
?4??IntPtr???buffer???=???Marshal.AllocHGlobal(size);???
?5??try???
?6??{???
?7??Marshal.Copy(bytes,???0,???buffer,???size);???
?8??return???Marshal.PtrToStructure(buffer,???strcutType);???
?9??}???
10??finally???
11??{???
12??Marshal.FreeHGlobal(buffer);???
13??}???
14??}?
