       获取当前活动的AutoCAD对象  ,下面语句只适合AutoCAD打开的情况,否则会发生错误,对于AutoCAD没有打开的情况后续会阐述。

View Code
namespace AcadExample
{
    public class AutoCADConnector : IDisposable
    {
        private AcadApplication _application;
        private bool _initialized;
        private bool _dispoased;

        public AutoCADConnector()
        {
            try
            {
                //获取当前活动的AutoCAD对象,对于AutoCAD2000和AutoCAD2002,则把16改成15
                _application = (AcadApplication)Marshal.GetActiveObject("AutoCAD.Application.16");
            }
            catch
            {
                try
                {
                    //创建一个新的实例并作标记
                    _application = new AcadApplication();
                    _initialized = true;
                }
                catch
                {
                    throw;
                }

            }
        }
        public AcadApplication Application
        {
            get
            {
                return _application;
            }
        }

        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }
        //我们自己创建AutoCAD实例,调用此方法
        protected virtual void Dispose(bool disposing)
        {
            //退出方法,避免内存泄露
            if (!this._dispoased && _initialized)
            {
                _application.Quit();
                _dispoased = true;

            }
        }

    }
}
