有没有一种方法可以从表格中的OLEObject字段中提取AutoCAD图形和图片？

using AutoCAD;
using System;

namespace ExtractCADFromTable
{
    class Program
    {
        static void Main(string[] args)
        {
            // Connect to AutoCAD
            AcadApplication acadApp = new AcadApplication();
            acadApp.Visible = true;

            // Open the table file
            AcadDocument doc = acadApp.Documents.Open("C:\\path\\to\\table.dwg");

            // Access the table and extract OLEObject field
            AcadTable table = (AcadTable)doc.ModelSpace.Item(0); // Assuming the table is the first object in the model space
            foreach (AcadCell cell in table.Cells)
            {
                if (cell.ObjectType == AcCellType.acCellTypeMText) // Assuming the OLEObject field is MText type
                {
                    AcadMText mtext = (AcadMText)cell.GetObject(AcGetObjectOption.acGetForRead);
                    if (mtext.FieldType == AcMTextFieldType.acFieldOLE) // Assuming the OLEObject field contains AutoCAD graphics or images
                    {
                        // Extract AutoCAD graphics or images from the OLEObject field
                        // ...
                    }
                    mtext.Close();
                }
            }

            // Close the document and disconnect from AutoCAD
            doc.Close();
            acadApp.Quit();
        }
    }
}
