Autodesk.Revit.DB.ReferencePointArrayIterator

Autodesk.Revit.DB.ReferencePointArrayIterator是一个用于迭代Autodesk.Revit.DB.ReferencePointArray中参照点的类。参照点是在Revit中定义的可移动点，通常用于约束和定位。

构造函数

public ReferencePointArrayIterator(ReferencePointArray referencePointArray)

• referencePointArray: 要迭代的参照点数组

属性

public ReferencePoint Current { get; }

• Current: 获取ReferencePointArrayIterator当前指向的Autodesk.Revit.DB.ReferencePoint对象。

方法

public bool MoveNext()

• MoveNext(): 将ReferencePointArrayIterator指针向下移动到参照点数组中的下一个元素。如果成功移动，则返回true，否则返回false。

public void Reset()

• Reset(): 重置迭代器将指针移回参照点数组的第一个元素。

示例

以下示例演示如何使用ReferencePointArrayIterator迭代ReferenceArray中的参考点并将它们的坐标打印到控制台上：

using Autodesk.Revit.DB;

// ...

public void IterateReferenceArray(ReferenceArray referenceArray)
{
    ReferencePointArray referencedPoints = new ReferencePointArray();

    foreach (Reference reference in referenceArray)
    {
        Element elem = doc.GetElement(reference);
        ReferencePoint rp = elem.Location as ReferencePoint;
        if(rp != null)
            referencedPoints.Append(rp);
    }

    ReferencePointArrayIterator it = referencedPoints.ForwardIterator();
    while(it.MoveNext())
    {
        ReferencePoint rp = it.Current;
        XYZ coordinate = rp.Position;
        Console.WriteLine(coordinate.ToString());
    }
}

异常

• ArgumentNullException: 当传入的参考点数组为null时抛出的异常信息。
