从C#字符串属性获取数组

本文介绍了从C#字符串属性获取数组的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在从数据库中检索一行，该行的属性是ID的逗号分隔列表

I'm retrieving a row from a database that has an attribute which is a comma separated list of ID's

1,2,3,4,5

在我的POCO中可以做这样的事情来找回阵列吗?

In my POCO is it possible to do something like this to get an array back?

public string SomeIDs { get { return SomeIDs.split(','); } set; }

很抱歉，为了澄清，我正在设置一个字符串，并想返回一个字符串数组

Sorry, to clarify, I am setting with a string and want to return a string array

推荐答案

您不能有一个接受string并返回string[]的设置器.您需要公开一个接受string的属性，以及一个只读属性(如下所示)，该属性从该字符串返回已解析的数组:

You can't have a setter which accepts a string and returns a string[]. You'll need to expose one property which accepts a string, and a read-only property (as below) which returns a parsed array from that string:

private static readonly string[] emptyIds = new string[0]; public string SomeIds { get; set; } public string[] ParsedIds { get { return !string.IsNullOrEmpty(SomeIds) ? SomeIds.Split(',') : emptyIds; } }
