Question

这是我可以在dwg file中打印属性的程序，但问题是mtext打印的值如下：项目：534Phase：1Zone：A（0530）项目：534阶段：1区域：A（0520）等等，但我希望输出像项目：534 阶段1 区：一（0530）（0520）。

如果我不误解你要做的事，你应该分开不同的任务：

构建文本的开头以使用文件名打印（具有匹配模式）。
添加所选属性的值文本末尾的块。

在AutoCAD中将文本打印为MText

[CommandMethod("ATT")]
public void ListAttributes()
{
    Document acDoc = Application.DocumentManager.MdiActiveDocument;
    Editor ed = acDoc.Editor;
    Database db = acDoc.Database;

    // build the begining of the text from the filename
    string filename = Path.GetFileNameWithoutExtension(acDoc.Name);
    string pattern = @"^(?<code>\w+)-[CSDWM](?<phase>\d+)(?<zone>[A-Z])-\w+$";
    //  pattern description:
    //  ^(?<code>\w+)   'code' named group: one or more word characters at the begining
    //  -               one hyphen (literal)
    //  [CSDWM]         one alphabetic character (C, S, D, W or M)
    //  (?<phase>\d+)   'phase' named group: one or more digits
    //  (?<zone>[A-Z])  'zone' named group: one alphabetic character
    //  -               one hyphen (literal)
    //  \w+$            one or more world characters at the end
    Match match = Regex.Match(filename, pattern);
    if (!match.Success)
    {
        ed.WriteMessage("\n The document file name does not match the pattern.");
        return;
    }
    var groups = match.Groups;
    string text = $"Project:{groups["code"]} Phase:{groups["phase"]} Zone:{groups["zone"]}";

    // Build a filter list so that only "NAL-SCRTAG"
    // block references are selected

    PromptSelectionResult res = ed.GetSelection(opts, filter);

        return;

    // Start the transaction
    using (Transaction tr = db.TransactionManager.StartTransaction())
    {
        try
        {
            // use a HashSet to avoid duplicated values
            HashSet<string> attValues = new HashSet<string>();

            // add the attributes values at the end of the text
            foreach (ObjectId blkId in res.Value.GetObjectIds())
            {
                BlockReference blkRef = (BlockReference)tr.GetObject(blkId, OpenMode.ForRead);
                foreach (ObjectId attId in blkRef.AttributeCollection)
                {
                    AttributeReference attRef = (AttributeReference)tr.GetObject(attId, OpenMode.ForRead);
                    string str = (attRef.TextString);
                    if (attValues.Add(str)) // returns false if attValues already contains str
                    {
                        text += $" ({str})"; // adds the attribute text string at the end of the text
                    }
                }
            }

            // add the mText to the current space
            var curSpace = (BlockTableRecord)tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite);
            MText mtext = new MText();
            mtext.Location = startPoint;
            mtext.Contents = text;
            curSpace.AppendEntity(mtext);
            tr.AddNewlyCreatedDBObject(mtext, true);
            tr.Commit();
        }
        catch (Autodesk.AutoCAD.Runtime.Exception ex)
        {
            ed.WriteMessage(("Exception: " + ex.Message));
        }
    }
}

在单个程序中创建两个不同的mtext
