AutoCADArchitecture二次开发中的错误处理和调试

在AutoCADArchitecture二次开发过程中，错误处理和调试是确保应用程序稳定性和可靠性的重要环节。本节将详细介绍如何在AutoCADArchitecture二次开发中有效地处理错误和进行调试，包括常见的错误类型、错误处理策略、调试工具和技巧。

常见的错误类型

在AutoCADArchitecture二次开发中，常见的错误类型可以分为以下几类：

1.语法错误

语法错误是最常见的错误类型，通常在编写代码时由于语法不正确导致。AutoCADArchitecture二次开发主要使用C#、VisualBasic.NET和LISP等编程语言，每种语言都有其特定的语法规范。

例子：C#语法错误

//错误代码

publicvoidDrawRectangle()

{

Lineline1=newLine(newPoint3d(0,0,0),newPoint3d(10,0,0)

Lineline2=newLine(newPoint3d(10,0,0),newPoint3d(10,10,0);

Lineline3=newLine(newPoint3d(10,10,0),newPoint3d(0,10,0);

Lineline4=newLine(newPoint3d(0,10,0),newPoint3d(0,0,0);

line1.Color=Color.FromColorIndex(ColorMethod.ByAci,1);

line2.Color=Color.FromColorIndex(ColorMethod.ByAci,1);

line3.Color=Color.FromColorIndex(ColorMethod.ByAci,1);

line4.Color=Color.FromColorIndex(ColorMethod.ByAci,1);

Databasedb=HostApplicationServices.WorkingDatabase;

using(Transactiontr=db.TransactionManager.StartTransaction())

{

BlockTablebt=(BlockTable)tr.GetObject(db.BlockTableId,OpenMode.ForRead);

BlockTableRecordbtr=(BlockTableRecord)tr.GetObject(bt[BlockTableRecord.ModelSpace],OpenMode.ForWrite);

btr.AppendEntity(line1);

btr.AppendEntity(line2);

btr.AppendEntity(line3);

btr.AppendEntity(line4);

tr.AddNewlyCreatedDBObject(line1,true);

tr.AddNewlyCreatedDBObject(line2,true);

tr.AddNewlyCreatedDBObject(line3,true);

tr.AddNewlyCreatedDBObject(line4,true);

tr.Commit();

}

}

//正确代码

publicvoidDrawRectangle()

{

Lineline1=newLine(newPoint3d(0,0,0),newPoint3d(10,0,0));

Lineline2=newLine(newPoint3d(10,0,0),newPoint3d(10,10,0));

Lineline3=newLine(newPoint3d(10,10,0),newPoint3d(0,10,0));

Lineline4=newLine(newPoint3d(0,10,0),newPoint3d(0,0,0))
