推荐答案

太糟糕了.现在修复它们！下次程序清晰，没有任何警告.
说真的:我从来没有听说过这样的事情.我的大量代码从2.0转换而来，没有任何抱怨.您只会收到一些过时"的警告.您所做的事情根本上是错误的.

我希望您打开为.NET 2.0创建的同一项目，并在使用VS 2010打开时进行转换吗?您确定所有消息都是编译错误，而不是警告?您能否隔离一个简单样本以显示2-3个错误并将其发布?

谢谢.

Too bad. Now fix them! Next time program clearly, without a single warning.
Seriously: I never heard of such things. A huge mass of my codes converted from 2.0 without a single complain. You only could receive some "obsolete" warnings. You''re doing something fundamentally wrong.

I hope you opened the same very project you created for .NET 2.0 and converted when opened with VS 2010? Are you sure all messages are compilation errors, not warnings? Could you isolate a minimalistic sample to show 2-3 errors and post it?

Thank you.

运行一次.Net 4.0程序，以确保正确安装了VS2010.

然后，正如SAKryukov前面提到的，在VS2010中打开.Net 2.0项目/解决方案，VS2010应该会自动为您进行转换(然后将显示一个报告，以显示转换过程中遇到的所有错误/问题).

Run a .Net 4.0 program once to make sure VS2010 has been installed correctly.

Then as mentioned by SAKryukov earlier, open the .Net 2.0 project / solution in VS2010 and VS2010 should automatically do the conversion for you (a report will then be displayed to show all errors / issues faced during conversion).
