在 XNA 4.0 中实现可移动平台的问题

我目前正在学习本教程：http://robotfootgames.com/xna-tutorials/78-xna-platformer-starter-kit-movable-platforms

它基于以下代码示例：http://xbox.create.msdn.com/en-US/education/catalog/sample/platformer

除了这段代码之外，一切似乎都可以工作，它给了我一堆错误：

private Rectangle HandleCollision(Rectangle bounds, TileCollision collision, Rectangle tileBounds)
{
Vector2 depth = RectangleExtensions.GetIntersectionDepth(bounds, tileBounds);
if (depth != Vector2.Zero)
{
    float absDepthX = Math.Abs(depth.X);
    float absDepthY = Math.Abs(depth.Y);
    // Resolve the collision along the shallow axis.
    if (absDepthY < absDepthX || collision == TileCollision.Platform)
    {
        // If we crossed the top of a tile, we are on the ground.
        if (previousBottom <= tileBounds.Top)
            isOnGround = true;
        // Ignore platforms, unless we are on the ground.
        if (collision == TileCollision.Impassable || IsOnGround)
        {
            // Resolve the collision along the Y axis.
            Position = new Vector2(Position.X, Position.Y + depth.Y);
            // Perform further collisions with the new bounds.
            bounds = BoundingRectangle;
        }
    }
    else if (collision == TileCollision.Impassable) // Ignore platforms.
    {
        // Resolve the collision along the X axis.
        Position = new Vector2(Position.X + depth.X, Position.Y);
        // Perform further collisions with the new bounds.
        bounds = BoundingRectangle;
    }
 }
 return bounds;
}

有谁知道如何解决以下错误（我尝试了自己，它似乎只会导致代码进一步中断）：

看起来有人没有正确转义他们的 HTML。只需将每个&lt;替换为<，代码就可以工作。
