关于autocad的二次开发！！

[will_chen891010]

[CommandMethod("cre")]
public void cre()
{
int i,j;
MText mt = new MText();

TypedValue[] ty = new TypedValue[] { new TypedValue((int)DxfCode.Text,mt) };
SelectionFilter sel = new SelectionFilter(ty);
SelectionFilter fil = new SelectionFilter(ty);
Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;
PromptSelectionOptions re = new PromptSelectionOptions();
PromptSelectionResult su = ed.GetSelection(re );
if (su.Status != PromptStatus.OK)
{
return;
}
Autodesk.AutoCAD.EditorInput.SelectionSet SS = su.Value;
ObjectId[] idArray;
idArray = SS.GetObjectIds();
i = idArray.Length;
StreamWriter strw = File.CreateText("d:\\temp\\Mmmmtest.txt");
strw.WriteLine(i.ToString());


for (j = 0; j <= i - 1; j++)
{
//try
//{
if (idArray[j].GetObject(OpenMode.ForRead).GetType() is MText)
{


mt = (MText)idArray[j].GetObject(OpenMode.ForRead);
strw.WriteLine(mt.Contents.ToString());
}
else
{
continue;
}





}
strw.Close();


}
这编译都通过了，是关于autocad的二次开发的，目的是将text读取到txt文件中！！但是一再cad中用连autocad都直接挂了！！！说出现致命错误！高手救救火啊！！

你这是在读扩展数据吗？还是每个对象上的文本？如果只是读一般的数据不需要这么长的代码
