我正在使用 Spring.NET 配置一些对象，并且我编写了一个 FactoryObject 来配置 Quartz.NET 日历。
它有如下所示的属性，我们当然希望使用 Spring.NET 进行配置
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Quartz.Impl.Calendar;
using Spring.Objects.Factory;
namespace My.Package.TaskExecutorDemo
{
/// <summary>
/// TODO:
/// </summary>
public class WeeklyCalendarFactoryObject : WeeklyCalendar, IFactoryObject
{
private ISet<DayOfWeek> _daysOfWeek = new HashSet<DayOfWeek>();
public ISet<DayOfWeek> DaysOfWeekExcluded
{
get { return _daysOfWeek; }
set
{
if (value == null)
{
throw new ArgumentNullException("DaysOfWeekExcluded");
}
_daysOfWeek = value;
}
}
//Everything else ...
}
}
它由以下对象定义配置。
<object id="weeklyCalendar" type="My.Package.TaskExecutorDemo.WeeklyCalendarFactoryObject, TaskExecutorDemo">
<property name="DaysOfWeekExcluded">
<set element-type="System.DayOfWeek, mscorlib">
<value>Friday</value>
<value>Saturday</value>
<value>Sunday</value>
</set>
</property>
</object>
但是在启动时会抛出以下异常:
Spring.Objects.Factory.ObjectCreationException: Error creating object with name 'weeklyCalendar' defined in 'config [C:\Users\username\some\path\TaskExecutorDemo\bin\Debug\TaskExecutorDemo.exe.Config#spring/objects] line 7' : Initialization of object failed : Unable to cast object of type System.Collections.Generic.HashSet`1[System.DayOfWeek]' to type 'Spring.Collections.ISet'.
System.InvalidCastException: Unable to cast object of type 'System.Collections.Generic.HashSet`1[System.DayOfWeek]' to type 'Spring.Collections.ISet'.
但我没有在我的代码中的任何地方引用 Spring.Collections.ISet。我如何让 Spring.NET 正确配置我的 ISet 属性？
最佳答案
根据 setting generic collection values 上的文档ISet<T> 不支持;只有通用集合 IDictionary<TKey, TValue>和 IList<T>得到支持。尝试通过显式配置显式 HashSet<T>使用 constructor taking an IEnumerable<T> .
关于c# - Spring.NET 无法转换为类型 Spring.Collections.Set，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18189295/
