C/C++中的結構類型數據在C#下的轉換
在做硬件對接開發的時候，會碰到SDK接口數據類型的轉換，而我這一次碰到的是C/C++中的結構怎樣轉換到C#。
例如我們在C/C++下的結構數據如下：
typedef struct
{
char sLibName[ 256 ];
char sPathToLibrary[ 256 ];
INT32 iEntries;
INT32 iUsed;
UINT16 iSort;
UINT16 iVersion;
BOOLEAN fContainsSubDirectories;
INT32 iReserved;
} LIBHEADER;
我們想把它轉成C#下的結構類型如下：
public struct LIBHEADER
{
public char[] sLibName;
public char[] sPathToLibrary;
public Int32 iEntries;
public Int32 iUsed;
public UInt16 iSort;
public UInt16 iVersion;
public Boolean fContainsSubDirectories;
public Int32 iReserved;
}
看上去好像沒問題了，呵呵呵，其實這樣是不行的，我們得再給C#編譯器一些信息，告訴它一些字符數組的大小。然后它們在C#下面長得樣子就變成這樣：
[StructLayout(LayoutKind.Sequential)]
public struct LIBHEADER
{
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 256)]
public char[] sLibName;
[MarshalAs(UnmanagedType.ByValArray, SizeConst = 256)]
public char[] sPathToLibrary;
public Int32 iEntries;
public Int32 iUsed;
public UInt16 iSort;
public UInt16 iVersion;
public Boolean fContainsSubDirectories;
public Int32 iReserved;
}
然后寫一個函數負責轉換。
public StructType ConverBytesToStructure<StructType>(byte[] bytesBuffer)
{
// 檢查長度。
if (bytesBuffer.Length != Marshal.SizeOf(typeof(StructType)))
{
throw new ArgumentException("bytesBuffer參數和structObject參數字節長度不一致。");
}
IntPtr bufferHandler = Marshal.AllocHGlobal(bytesBuffer.Length);
for (int index = 0; index < bytesBuffer.Length; index++)
{
Marshal.WriteByte(bufferHandler, index, bytesBuffer[index]);
}
StructType structObject = (StructType)Marshal.PtrToStructure(bufferHandler, typeof(StructType));
Marshal.FreeHGlobal(bufferHandler);
return structObject;
}
然后我們的函數用例是這樣：
FileStream file = File.OpenRead(@"D:/Jagged Alliance 2 Gold/INSTALL.LOG");
byte[] buffer = new byte[Marshal.SizeOf(typeof(LIBHEADER))];
file.Read(buffer, 0, buffer.Length);
LIBHEADER testValue = CommonTools.ConverBytesToStructure<LIBHEADER>(buffer);
string libName = new string(testValue.sLibName);
string pathToLibrary = new string(testValue.sPathToLibrary);
如果想去掉后面兩句的char數組的轉換哪代碼如下
C#中的結構代碼
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi)]
public struct LIBHEADER
{
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 256)]
public string sLibName;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 256)]
public string sPathToLibrary;
public Int32 iEntries;
public Int32 iUsed;
public UInt16 iSort;
public UInt16 iVersion;
public Boolean fContainsSubDirectories;
public Int32 iReserved;
}
