更改线型说明 （.NET）
线型可以具有与之关联的描述。描述提供线型的 ASCII 表示形式。您可以使用属性分配或更改线型说明。AsciiDescription 线型描述最多可以包含 47 个字符。描述可以是注释，也可以是一系列下划线、点、破折号和空格，以显示线型模式的简单表示形式。 更改线型的描述以下示例更改当前线型的描述。 VB.NETImports Autodesk.AutoCAD.Runtime
Imports Autodesk.AutoCAD.ApplicationServices
Imports Autodesk.AutoCAD.DatabaseServices
<CommandMethod("ChangeLinetypeDescription")> _
Public Sub ChangeLinetypeDescription()
'' Get the current document and database
Dim acDoc As Document = Application.DocumentManager.MdiActiveDocument
Dim acCurDb As Database = acDoc.Database
'' Start a transaction
Using acTrans As Transaction = acCurDb.TransactionManager.StartTransaction()
'' Open the Linetype table record of the current linetype for write
Dim acLineTypTblRec As LinetypeTableRecord
acLineTypTblRec = acTrans.GetObject(acCurDb.Celtype, _
OpenMode.ForWrite)
'' Change the description of the current linetype
acLineTypTblRec.AsciiDescription = "Exterior Wall"
'' Save the changes and dispose of the transaction
acTrans.Commit()
End Using
End Sub
C#using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
[CommandMethod("ChangeLinetypeDescription")]
public static void ChangeLinetypeDescription()
{
// Get the current document and database
Document acDoc = Application.DocumentManager.MdiActiveDocument;
Database acCurDb = acDoc.Database;
// Start a transaction
using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction())
{
// Open the Linetype table record of the current linetype for write
LinetypeTableRecord acLineTypTblRec;
acLineTypTblRec = acTrans.GetObject(acCurDb.Celtype,
OpenMode.ForWrite) as LinetypeTableRecord;
// Change the description of the current linetype
acLineTypTblRec.AsciiDescription = "Exterior Wall";
// Save the changes and dispose of the transaction
acTrans.Commit();
}
}
