自定义 ConfigurationElementCollection 抛出

Question

我正在尝试ConfigurationSection使用ConfigurationElementCollection. 但是当我使用它时会抛出一个ConfigurationErrorsException带有 2 个详细信息的异常TargetInvocationException并且MissingMethodException我在构造函数中安慰一些消息，结果只是“新的 AssembySettingSection”。在 AssembySettingSection base["settings"] 处抛出异常。应用配置<?xml version="1.0" encoding="utf-8"?><configuration>  <configSections>    <section name="AssembySetting" type="IngoWinService.AssembySettingSection, IngoWinService"/>  </configSections>  <AssembySetting>    <settings>      <add name="IngoWinService.Haier.Service" assemby="IngoWinService.Haier" />    </settings>  </AssembySetting>  <startup>    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />  </startup></configuration>部分代码（需要时发布其他人）public class AssembySettingSection : ConfigurationSection{    public AssembySettingSection()    {        System.Console.WriteLine("new AssembySettingSection");    }    [ConfigurationProperty("settings", IsDefaultCollection = false)]    [ConfigurationCollection(typeof(AssembySettingCollection))]    public ConfigurationElementCollection Settings    {        get        {            return base["settings"] as AssembySettingCollection;//Throw Exception        }    }}

抱歉，我在问题中使用了错误的元素类型。无论如何，为其他用户回答这个问题。

问题已解决。

public class AssembySettingSection : ConfigurationSection

{

    public AssembySettingSection()

    {

        System.Console.WriteLine("new AssembySettingSection");

    }

    [ConfigurationProperty("settings", IsDefaultCollection = false)]

    [ConfigurationCollection(typeof(AssembySettingElement))]//Changed AssembySettingCollection to AssembySettingElement

    public AssembySettingCollection Settings

    {

        get

        {

            return base["settings"] as AssembySettingCollection;

        }

    }

}
