【求助】使用c#在CAD中批量创建图层
小弟最近在做的一个小项目，想从excel文档中批量读取数据到CAD创建图层。采用将excel中的数据存入不同的数组，再在创建CAD图层的时候应用这些数组的方法。
现在对于图层名字，颜色和线型的设置都没有问题。
对于线宽：acLineWeights = LineWeight.LineWeight005;acLyrTblRec.LineWeight = acLineWeights ；可以创建单一的图层线宽。
但是想要将批量创建图层线宽就发生了问题。
我的想法是，
string u = LineWeight005；
acLyrTblRec.LineWeight = LineWeight.（u）；
只要这种参数化的设置线宽可以实现，那么就可以实现批量导入。
望有人赐教，不甚感激！（附代码）
