属性使用Spring.Net注入数组 [英] Property Inject an Array with Spring.Net

问题描述

我一直在使用Spring.Net IoC容器，可以使用它来注入类型为IList甚至IList<T>的属性，但是我对如何注入类型的属性有些困惑string[].

I've been using the Spring.Net IoC container and can use it to inject properties that are of type IList and even IList<T> but I'm a bit stumped as to how to inject a property thats of type string[].

在XSD中似乎没有定义<array>元素，并且使用<list> <value> </list>也不起作用.

There doesn't seem to be an <array> element defined in the XSD's and using <list> <value> </list> doesn't work either.

如果任何人都可以发布xml，我需要使用数组作为属性注入，将不胜感激

If anyone could post the xml I need to inject using an array for a property it'd be much appreciated

推荐答案

如所述

As mentioned here in the documentation you can inject a string array as a comma delimited string (not sure what the syntax is for escaping actual commas in strings if necessary). In other words your config would look something like this:

<object id="MyObject" type="Blah.SomeClass, Blah" >
    <property name="StringArrayProperty" value="abc,def,ghi" />
</object>

如果您需要更复杂的内容(例如，如果要从其他参考中查找各个值而不是对其进行硬编码)，则可以使用以下语法手动构造string[]:

Manually constructing a string[] with the following syntax also works, if you need something more complex (for example if you're looking the individual values up from some other reference rather than hard coding them):

<object id="TestStrArr" type="string[]" >
    <constructor-arg value="3" />
    <property name="[0]" value="qwe" />
    <property name="[1]" value="asd" />
    <property name="[2]" value="zxc" />
</object>

<object id="MyObject" type="Blah.SomeClass, Blah" >
    <property name="StringArrayProperty" ref="TestStrArr" />
</object>
