Article Introduction：When using HTML5 inputtype="date", the core reasons and solutions for inconsistent date format display are as follows: 1. You must always use the YYYY-MM-DD format to set and get the value, otherwise it may cause recognition failure; 2. The browser display format varies according to system and region settings, but does not affect the actual value; 3. If you need to uniformly display the format, you should use a third-party library to replace the native controls; 4. Server-side verification is required and a fallback solution is provided for unsupported browsers, such as using the text type to cooperate with the JS plug-in to handle it.

They provide additional information that can be queried through reflection at runtime and play a key role in metaprogramming. 1. Attributes are applied to target elements through square brackets, such as marking methods are outdated; 2. Custom attributes can be created by inheriting System.Attribute, such as adding description information to the class; 3. Use reflection to dynamically read attribute content, which is very useful for building systems such as serializers, ORMs or test runners; 4. Attributes are often used to mark members that need to be ignored, annotated unit test methods, and define WebAPI model verification rules. 5. In metaprogramming, attributes are combined with reflection to support plug-in automatic detection.
