插入块（数据库）、预览图 错误调试

 下面是在新打开的文档中插入数据库或插入块参照（未解决）

using System.IO;
using System.Reflection;

namespace IfoxDemo;
public static class FZK
{//复制快到另一个图
    [CommandMethod("xx")]
    public static void FZKDemo()
    {//新打开一个指定文档，把另一个文档当成快插入到新文档，缩放新文档视图
        var doca = Env.Document;
        using var tr1= new DBTrans(doca,true,true);
        DocumentCollection docs = Application.DocumentManager;
        string newdocPath = "C:\\Users\\Administrator\\Desktop\\演示合并dwg\\33.dwg";
        Document newdoc = docs.Open(newdocPath, false);//.Add("acad.dwt");//docs.Add("新");
        docs.MdiActiveDocument = newdoc;//新文档设置为当前文档
        System.Windows.Forms.Application.DoEvents();
        string blockPath = @"C:\Users\Administrator\Desktop\XK新块.dwg";
        using var tr = new DBTrans(newdoc,true,true);
        var btrid =  tr.BlockTable.GetBlockFrom(blockPath, false);
        tr.ModelSpace.Database.InsertBlock( btrid,Point3d.Origin);
        System.Windows.Forms.Application.DoEvents();
        //var ed = tr.Editor;
        //ed.Redraw();
        //ed.ZoomExtents();//目前缩放失败,关闭时需保存，否则插入不进去块
        //Env.Editor.ZoomExtents();//第一个图可以缩放和重画，打开的新图缩放失败
        //Env.Editor.Redraw();
    }


}

 

批量插入失败：

using System.IO;
using System.Reflection;
using System.Windows.Forms;

namespace IfoxDemo;
public static class FZK
{//复制快到另一个图
    [CommandMethod("xx")]
    public static void FZKDemo()
    {//新打开一个指定文档，把另一个文档当成快插入到新文档，缩放新文档视图
        var doca = Env.Document;
        using var tr1= new DBTrans(doca,true,true);
        DocumentCollection docs = Application.DocumentManager;
        FolderBrowserDialog dialog = new FolderBrowserDialog();
        dialog.Description = "请选择dwg文件所在文件夹：";  // 设置对话框的标题
        DialogResult dlgResult = dialog.ShowDialog();
        if (dlgResult == DialogResult.OK)
        {
            string dialogPathName = dialog.SelectedPath;
            string[] fileNames = Directory.GetFiles(dialogPathName, "*.dwg", SearchOption.AllDirectories);//此行代码为只合并dwg
            foreach (string fileName in fileNames)
            {
              // string newdocPath = "C:\\Users\\Administrator\\Desktop\\演示合并dwg\\33.dwg";
                Document newdoc = docs.Open(fileName, false);//.Add("acad.dwt");//docs.Add("新");
                docs.MdiActiveDocument = newdoc;//新文档设置为当前文档
                System.Windows.Forms.Application.DoEvents();
                string blockPath = @"C:\Users\Administrator\Desktop\XK新块.dwg";
                using var tr = new DBTrans(newdoc, true, true);
                var btrid = tr.BlockTable.GetBlockFrom(blockPath, false);
                tr.ModelSpace.Database.InsertBlock(btrid, Point3d.Origin);//目前批量插入还未能成功
                System.Windows.Forms.Application.DoEvents();
               // newdoc.CloseAndSave(newdoc.Database.Filename );
               
                //var ed = tr.Editor;
                //ed.Redraw();
                //ed.ZoomExtents();//目前缩放失败,关闭时需保存，否则插入不进去块
                //Env.Editor.ZoomExtents();//第一个图可以缩放和重画，打开的新图缩放失败
                //Env.Editor.Redraw();
                tr.Commit();
            }
        }
    }

下面是dxf预览图问题（未解决）

     if (dlgResult == DialogResult.OK)
     {
         int counter = 0;
         string dialogPathName = dialog.SelectedPath;
         // 新文件夹的名称 和 新文件夹路径的名称
