How are enumeration values used? Summarize enumeration value Instance usage

This article mainly introduces C # from the enumeration value to get the corresponding text description of the relevant information, the need for friends can refer to C # from the enumeration value to get the corresponding text description of the enumeration value in the display, you need to display the enumeration value corresponding to the text string. One option is to use switch or if at the call to determine the enumeration value and then assign it to a different text string, but this can be cumbersome if more places are used. Of course, some people say that, in this case, you can encapsulate a method for this enumeration value and then call it. What if there are multiple enumeration types that require this? Is there a more general solution? Some.

Summary: Adding new values to a list is a common and necessary requirement. Pattern designers often want to build a method of adding added value in the system architecture, and that added value is unknown at design time. How does the pattern designer create a list of extensible, easy-to-implement enumeration values? This article describes several ways to achieve this goal. Pattern designers and implementation personnel need an extended

4. MySQL list partition

Summary: The list partition and range partition are very similar, the main difference is that the list is a collection of enumeration value lists, and range is a continuous set of interval values. The two are very similar in terms of syntax. It is also recommended that the list partition column is a non-null column, otherwise inserting a null value if there is no null value in the enumeration list fails to insert, which is not the same as other partitions, and the range partition stores it as a minimum partition value, which is hash\key into 0 storage. The primary list partition only supports shaping, and non-shaping fields need to be converted to shaping by functions; After version 5.5, you can use the list column partition to support non-shaping fields, and the column partition
