| 構造体 | 解説 |
| Bool | A boolean value stored on 4 bytes (instead of 1 in .NET). |
| ColorF | Represents a color in the form of rgba. |
| DataBox | Provides access to data organized in 3D. |
| DataPointer | Pointer to a native buffer with a specific size. |
| DataRectangle | Provides access to data organized in 2D. |
| HResult | Result structure for COM methods. |
| Matrix3x2 | Direct2D Matrix3x2 3x2. Use Matrix3x2and implicit cast to Matrix3x2. |
| Matrix4x4 | Represents a 4x4 mathematical matrix. |
| Matrix5x4 | Represents a 4x4 mathematical Matrix5x4. |
| Point2D | Structure specifing a point with double X and Y coordinates. |
| Point2F | Structure specifing a point with float X and Y coordinates. |
| Point2L | Structure specifing a point with integer X and Y coordinates. |
| PointerSize | The maximum number of bytes to which a pointer can point. Use for a count that must span the full range of a pointer. Equivalent to Windows type SIZE_T. |
| RectD | Structure specifing a rectangle with double Left, Top, Right, Bottom coordinates. |
| RectF | Define a RectF. This structure is slightly different from System.Drawing.RectangleF as it is internally storing Left, Top, Right, Bottom instead of Left, Top, Width, Height. Although automatic casting from and to System.Drawing.RectangleF is provided by this class. |
| RectL | Define a RectL. This structure is slightly different from System.Drawing.Rectangle as it is internally storing Left, Top, Right, Bottom instead of Left, Top, Width, Height. Although automatic casting from and to System.Drawing.Rectangle is provided by this class. |
| Size2D | Structure specifing a size with double Width and Height. |
| Size2F | Structure specifing a size with float Width and Height. |
| Size2L | Structure specifing a size with integer Width and Height. |
| Vector2 | Represents a two dimensional mathematical vector. |
| Vector3 | Represents a three dimensional mathematical vector. |
| Vector4 | Represents a four dimensional mathematical vector. |
| ViewportF | Defines the viewport dimensions using float coordinates for (X, Y, Width, Height, MinDepth, MaxDepth). |
