【MSCE C#】使用BodyFromSweep方法的问题

Question

ShapeElement shapeEle0 = new ShapeElement(dgnmodel, null, ptArr0);

var temp = dLJ.XLverts4S.ToArray();
DPoint3d[] LinePoint = new DPoint3d[dLJ.XLverts4S.count];
for (int i = 0; i < dLJ.XLverts4S.count; i++)
{ LinePoint[i] = dLJ.XLverts4S[i]; }
LineStringElement lineEle = new LineStringElement(dgnmodel, null, temp);
CurveVector curVecPath = lineEle.GetCurveVector();

CurveVector curVecShape = shapeEle0.GetCurveVector();
CurveVector[] curVecShapePtr = new CurveVector[1];
curVecShapePtr[0] = curVecShape;

Bentley.DgnPlatformNET.SolidKernelEntity[] solid = new SolidKernelEntity[1];

Bentley.DgnPlatformNET.Create.BodyFromSweep(out solid, curVecShapePtr, LinePoint, curVecPath, dgnmodel, null); 代码如上，其中 lineEle 是一个线串， shapeEle0 是由点数组创建好的面元素，在线串的端点，想实现面沿线拉伸形成体，但执行最后一行语句时总是报错。请教各位问题出在哪里

经过测试，这些新封装的BodyFromSweep、BodyFromLoft似乎都有问题。 
 还是先转到老的Interop对象模型使用吧。样例如下： 
 public static void SweepAlong(string unparsed)
 {
 BIM.Application app = BMI.Utilities.ComApp;

 BIM.Point3d[] aPoints = new BIM.Point3d[4];
 aPoints[0] = app.Point3dFromXYZ(1.5, -1.5, 4);
 aPoints[1] = app.Point3dFromXYZ(-1.5, -1.5, 4);
 aPoints[2] = app.Point3dFromXYZ(-1.5, 1.5, 4);
 aPoints[3] = app.Point3dFromXYZ(1.5, 1.5, 4);
 BIM.ShapeElement profile = app.CreateShapeElement1(null, ref aPoints, BIM.MsdFillMode.NotFilled);

 BIM.Point3d[] bPoints = new BIM.Point3d[3];
 bPoints[0] = app.Point3dFromXYZ(0, 0, 0);
 bPoints[1] = app.Point3dFromXYZ(0, 0, 1);
 bPoints[2] = app.Point3dFromXYZ(0, 0, 2);
 BIM.LineElement path = app.CreateLineElement1(null, ref bPoints);

 BIM.SmartSolidElement result = app.SmartSolid.SweepProfileAlongPath(profile, path);
 app.ActiveModelReference.AddElement(result);
 }
