覆盖null的属性getter [英] Override property getter for nulls

问题描述

我正在使用带有现有sql server ce数据库的DbContext生成器（最终我希望相同的代码可以运行时可以根据sql server运行）。

I am using the DbContext generator with ef an exisiting sql server ce database (eventually I would like the same code to be runtime swichable run against sql server).

我想在可以为空的字符串属性上使用getter方法，以便在db包含null时返回一个emty字符串。  编写一个测试null的getter似乎很容易，如果为null则返回一个空格。 如果我更改生成的类
中的代码，如果我重新生成类，它将被覆盖。 我怎么能这样做？

I would like to have the getter methodss on the nullable string properties to return an emty string when the db contains null.  It seems easy enough to write a getter that tests for null and returns a blank if null. If I change the code in the generated class, it will be overridden if I regenerate the classes.  How can I do this?
