微软BUG: 发现VS2010调试模式类似BUG问题 比较有趣!

}前台调用: <%SNS_DCC.MongoDBInfo.GetInstance().BlogsDBNameQueue.Push("456"); %>必须在程序第一次运行时候有用!在get
{
    GetPrepare();
    return this.blogsDBNameQueue;
}加一个断点 跑到此处时this 是刚刚new的状态 new MongoDBInfo();
但是如果在每个方法中 加断点  你会发现 再次运行到此处 this 是从MongoDBInfo.dat 中读取的对象.
当然为了区别 是新new的还是读取的值 MongoDBInfo.dat  一定要是存有值得序列化文件
