1.目的
本文的目的是利用C#中选择集GetSelection函数得到CAD中标注尺寸
2.实现代码

//保存图形信息到Excel文件
string fileName = ed.OpenSaveDialog(db);
if (fileName == "") return;
TypedValue[] values = new TypedValue[]
{
//设定为标注图元
new TypedValue((int)DxfCode.Start,"DIMENSION"),
//new TypedValue((int)DxfCode.Start,"CIRCLE"),
};
//过滤标注图元
SelectionFilter filter = new SelectionFilter(values);
PromptSelectionResult psr = ed.GetSelection(filter);

List strY = new List();
//List ids = new List();
if (psr.Status == PromptStatus.OK)
{
SelectionSet sSet = psr.Value;
ObjectId[] ids = sSet.GetObjectIds();
//如果ids中没有数据则返回；
if (ids.Length == 0) return;
//开启事务处理
using (Transaction trans = db.TransactionManager.StartTransaction())
{
