C＃中的PathIterator

Question

在Java中，我们可以使用PathIterator遍历Shape的顶点（并检测循环和其他功能），我一直在尝试将以下代码转换为C＃，因为我无法找到类中的内容与PathIterator等效的C＃。那么有谁知道C＃中的等价类或方法是什么。

代码是：

private void processCircleShape(Circle circle, final Shape cellBoundaryPolygon) 
{
    initializeForNewCirclePrivate(circle);
    if (cellBoundaryPolygon == null) 
    {
        return;
    }
    PathIterator boundaryPathIterator = cellBoundaryPolygon.getPathIterator(null);
    double[] firstVertex = new double[2];
    double[] oldVertex = new double[2];
    double[] newVertex = new double[2];
    int segmentType = boundaryPathIterator.currentSegment(firstVertex);
    if (segmentType != PathIterator.SEG_MOVETO) 
    {
        throw new AssertionError();
    }
    System.arraycopy(firstVertex, 0, newVertex, 0, 2);
    boundaryPathIterator.next();
    System.arraycopy(newVertex, 0, oldVertex, 0, 2);
    segmentType = boundaryPathIterator.currentSegment(newVertex);
    while (segmentType != PathIterator.SEG_CLOSE) 
    {
        processSegment(oldVertex, newVertex);
        boundaryPathIterator.next();
        System.arraycopy(newVertex, 0, oldVertex, 0, 2);
        segmentType = boundaryPathIterator.currentSegment(newVertex);
    }
    processSegment(newVertex, firstVertex);
}

我认为它是Shape.RenderedGeometry（或DefiningGeometry），因为描述主要与

相匹配
