刚打开的文件为什么不能写入?

public void Test() { const string fn = "D:\\bb.dwg"; Document fDoc = Application.DocumentManager.Open(fn, false); Database fDB = null;// fDocumentACAD.Database; fDB = fDoc.Database; DocumentLock lk=fDoc.LockDocument(); fDatabaseDWG.SaveAs(fn, DwgVersion.Current); lk.Dispose(); //eFileAccessErr 刚打开的文件为什么不能写入？ }

现在给出我分析的原因。以上代码本身本无问题；出错又是事实，为什么呢？就是在于“调试方式”。我们大多在测试时用 “命令行” ，这本身并没有什么不对的，只是它对于当前的文档或库是有效的，对于后台的就不行了。如果强行在代码中切换操作的文档为当前。然而发出命令的是另外的文档对应的命令行。所以中间会中断直到回到发出命令的文档。这样始终存在一个错误的对应关系。故而调试会出错。

找到了原因，那么该如何向后台dwg文件写入数据呢？
