主要用途将c#的类数据保存为二进制文件，包含基本值类型和数组，字符串等。还有的三个指针数据操作类FakeStruct，FakeStructArray，FakeStringArray

我做过的项目，里面的UI的布局数据，kcp网络通信等都是使用DataBuffer打包的。当你的数据写完后调用ToBytes()函数，数据还原时直接使用构造函数public unsafe DataBuffer(byte[] dat)

写个示例

public unsafe struct TextData

    {

        public bool alignByGeometry;

        public TextAnchor alignment;

        public Int32 fontSize;

        public FontStyle fontStyle;

        public HorizontalWrapMode horizontalOverflow;

        public float lineSpacing;

        public bool resizeTextForBestFit;

        public Int32 resizeTextMaxSize;

        public Int32 resizeTextMinSize;

        public bool supportRichText;

        public Color color;

        public VerticalWrapMode verticalOverflow;

        public Int32 font;

        public Int32 text;

        public Int32 shader;

        public Int32 ex;

        public static int Size = sizeof(TextData);

        public static int ElementSize = Size / 4;

    }

DataBuffer buffer = new DataBuffer();

FakeStruct fake = new FakeStruct(buffer, TextData.ElementSize);

            TextData* data = (TextData*)fake.ip;

            data->alignByGeometry = txt.alignByGeometry;

            data->alignment = txt.alignment;

            data->fontSize = txt.fontSize;

            data->fontStyle = txt.fontStyle;

            data->horizontalOverflow = txt.horizontalOverflow;

            data->lineSpacing = txt.lineSpacing;

            data->resizeTextForBestFit = txt.resizeTextForBestFit;

            data->resizeTextMaxSize = txt.resizeTextMaxSize;

            data->resizeTextMinSize = txt.resizeTextMinSize;

            data->supportRichText = txt.supportRichText;

            data->verticalOverflow = txt.verticalOverflow;

            data->color = txt.color;

            data->text = buffer.AddData(txt.text);

            if (txt.font != null)

              data->font = buffer.AddData(txt.font.name);

            if (txt.material != null)

              data->shader = buffer.AddData(txt.material.shader.name);

buffer.fakeStruct=fake;

var dat = buffer.ToBytes();

恢复时

var buffer=new DataBuffer(dat);

data = *(TextData*)buffer.fakeStruct.ip;

           string shader = buffer.GetData(data.shader) as string;

          string  text= buffer.GetData(data.text) as string;

          string  fontName = buffer.GetData(data.font) as string;

还支持泛型值类型数组

        var index = DataBuffer.AddArray<Vector3>(new Vector3[66]);

        Vector3[] buf =  DataBuffer.GetArray<Vector3>(index);
