C          /C++中的結構類型數據在C#下的轉換
          

          
 
          
在做項目移植的時候，經常會碰到數據類型的轉換，而我這一次碰到的是C          /C++中的結構怎樣轉換到C#。折騰了一個晚上終于有一個完美的方案。
          
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);
          
OK,搞定。
          
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;
          
    }
          
其它代碼不用作修改便可使用。
