插入块或文本的C＃代码 [英] C# code to insert a block or text
问题描述
我正在尝试编写一个C＃程序，它将在不打开Autocad应用程序的情况下在图形中插入块或文本。我可以将Autocad应用程序作为后台进程运行。
我尝试了什么：
我实际上收到错误
发生System.InvalidProgramException
HResult = 0x8013153A公共语言运行时检测到无效程序。
Source =< can not evaluation ==exception =source =>
StackTrace：at Autodesk.AutoCAD.DatabaseServices.Database.get_TransactionManager（）
在下面运行这段代码
数据库sourceDb = new数据库（false，true）; //用于保存我们要导入的块的数据的临时数据库
尝试
{
sourceDb.ReadDwgFile（dwgPath，System.IO.FileShare 。读，真，）; //将DWG读入边数据库
ObjectIdCollection blockIds = new ObjectIdCollection（）; //创建一个变量来存储块标识符列表
Autodesk.AutoCAD.DatabaseServices.TransactionManager tm = sourceDb.TransactionManager; using（Transaction myT = tm.StartTransaction（））
{
//打开块表
BlockTable bt =（BlockTable）tm。 GetObject（sourceDb.BlockTableId，OpenMode.ForRead，false）;
//检查块表中的每个块
foreach（ObjectId btrId在bt）
{
BlockTableRecord btr =（BlockTableRecord）tm.GetObject（btrId，OpenMode.ForRead，false）;
//仅限添加命名&非布局块到复制列表
if（！btr.IsAnonymous&&！btr.IsLayout）
{
blockIds。添加（btrId）;
}
btr.Dispose（）;
}
}
//将块从源数据库复制到目标数据库
// IdMapping mapping = new IdMapping（）; sourceDb.WblockCloneObjects（blockIds，_database.BlockTableId，mapping，DuplicateRecordCloning.Replace，false）; _editor.WriteMessage（\ nCopied+ blockIds.Count.ToString（）+块定义从+ blockToImport +到当前图纸。）;
}
I’m trying to write a C# program which will insert a block or text in a drawing without opening the Autocad application. I’m ok to run the Autocad application as a background process.
What I have tried:
I’m actually getting an error
System.InvalidProgramException occurred
HResult= 0x8013153A Common Language Runtime detected an invalid program.
Source=<cannot evaluate="" the="" exception="" source="">
StackTrace: at Autodesk.AutoCAD.DatabaseServices.Database.get_TransactionManager()
While running this below piece of code
Database sourceDb = new Database(false, true); //Temporary database to hold data for block we want to import
try
{
sourceDb.ReadDwgFile(dwgPath, System.IO.FileShare.Read, true, ""); //Read the DWG into a side database
ObjectIdCollection blockIds = new ObjectIdCollection(); // Create a variable to store the list of block identifiers
Autodesk.AutoCAD.DatabaseServices.TransactionManager tm = sourceDb.TransactionManager; using (Transaction myT = tm.StartTransaction())
{
// Open the block table
BlockTable bt = (BlockTable)tm.GetObject(sourceDb.BlockTableId, OpenMode.ForRead, false);
// Check each block in the block table
foreach (ObjectId btrId in bt)
{
BlockTableRecord btr = (BlockTableRecord)tm.GetObject(btrId, OpenMode.ForRead, false);
// Only add named & non-layout blocks to the copy list
if (!btr.IsAnonymous && !btr.IsLayout)
{
blockIds.Add(btrId);
}
btr.Dispose();
}
}
// Copy blocks from source to destination database
//IdMapping mapping = new IdMapping(); sourceDb.WblockCloneObjects(blockIds, _database.BlockTableId, mapping, DuplicateRecordCloning.Replace, false); _editor.WriteMessage("\nCopied " + blockIds.Count.ToString() + " block definitions from " + blockToImport + " to the current drawing.");
}
推荐答案
c＃ - InvalidProgramException / Common语言运行时检测到无效程序 - 堆栈溢出 [ ^ ]
当您尝试在同一进程中混合使用64位和32位代码时，通常会得到类似的结果。
可能是您的AutoCAD安装是64位且您的应用程序编译为x86（32位）或首选32位已启用。查看您的项目属性并将目标设置为x64并再次尝试。
You usually get something like this when you try to mix 64- and 32-bit code in the same process.
It could be that your AutoCAD installation is 64-bit and your app is compiled as x86 (32-bit) or "Prefer 32-bit" is enabled. Look in your Project Properties and set the target to x64 and try it again.
