请教一下,如何在后期绑定中创建面域呢?

SurveyCAD 发表于 2016-4-6 10:17:51

在c#中通过activex方式操作AutoCAD,代码如下:

            dynamic[] circleObj=new dynamic
            double[] calpt = new double;
            calpt = 0; calpt = 0; calpt = 0;

            circleObj = AcadDoc.ModelSpace.AddCircle(cirPt, 10);
            //生成面域
            dynamic[] regionObject;
            regionObject = (dynamic[])AcadDoc.ModelSpace.AddRegion(circleObj); //执行到这句出现: 对象数组无效错误
            dynamic profileRegionObject = (dynamic)(regionObject);

调试的时候发生如下错误: 对象数组无效

请问各位有什么好的解决办法?

public virtual dynamic AddRegion(object ObjectList)返回值为dynamic

或者试试(object[])AcadDoc.ModelSpace.AddRegion()

(object[])AcadDoc.ModelSpace.AddRegion() 这种方法也出现相同的错误.

public virtual dynamic AddRegion(object ObjectList) 这个如何用的?

给你来个实例吧
Acad3DSolid damObjectCopy;
Acad3DPolyline[] polyline = new Acad3DPolyline;
AcadRegion regionObj;
try
{
damObjectCopy = (Acad3DSolid)damObject.Copy();
double[] regionCoords = new double, minPoint = new double, maxPoint = new
double;
object minPointObject, maxPointObject;
damObjectCopy.GetBoundingBox(out minPointObject, out maxPointObject);
minPoint = (double[])minPointObject;
maxPoint = (double[])maxPointObject;
regionCoords = minPoint; regionCoords = minPoint; regionCoords =
startHeight;
regionCoords = maxPoint; regionCoords = minPoint; regionCoords =
startHeight;
regionCoords = maxPoint; regionCoords = maxPoint; regionCoords =
startHeight;
regionCoords = minPoint; regionCoords = maxPoint; regionCoords =
startHeight;
polyline = AcadDoc.ModelSpace.Add3DPoly(regionCoords);
polyline.Closed = true;
object[] tempObject;
tempObject = (object[])AcadDoc.ModelSpace.AddRegion(polyline);
regionObj = (AcadRegion)(tempObject);
Acad3DSolid boolObjectB;
boolObjectB = AcadDoc.ModelSpace.AddExtrudedSolid(regionObj, endHeight - startHeight,
0.0);
damObjectCopy.Boolean(AcBooleanType.acIntersection, boolObjectB);
damObjectCopy.Layer = "划分后模型";
polyline.Delete();
regionObj.Delete();
}
catch
{
polyline.Delete();
erroInfoRichTextBox.Text += "在划分模型" + damObject.Layer.ToString()
+ "时：高程"+startHeight.ToString()+"至"+endHeight.ToString()+"出错！\n";
}

你这个是在前期绑定中可以吧? 在后期绑定中是没有AcadRegion ,Acad3DSolid 等等实体定义的.

把你的circleObj在作为参数时强类型化一下试试，或者直接强类型化circleObj

由于是后期绑定,没法强类型化啊!

这是雪山飞狐_lzh 通过后期绑定生成面域的程序,但是我执行的时候,只是画了一个正方形,并没有成功创建一个面域,请问是什么原因呢?

经测试是可以的，你再检查下代码。
