求助，为什么wpf(c#)不能步进调试部分类中的代码，vb可以
如题，我从网上下了个vb的wpf代码，改写成c#版本，但是调试中发现有一个usercontrol无易做图常实例化，原因是有一个grid组件没有被初始化，一直是null，进而在.clear()操作中报错。在vb中调试可以看到grid是在g.vb中的loadcomponent之后被赋值的，而c#中在g.cs中下的断点无效，无法知道到底是哪里出了问题！请问应该怎么改配置，还是c#本身就无法调试g.cs部分代码。另外grid==null可能是有哪些原因？谢谢！ --------------------编程问答-------------------- monthview.xaml.cs
