自定义配置中的C#配置错误异常

在msdn示例的帮助下，我进行了以下自定义配置。它返回System.Configuration.ConfigurationErrorsException，表示无法从assembly System.Configuration加载我的处理程序类

我做错了什么

配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="FTPLastModifiedGroup">
      <section
        name="FTPLastModified"
        type="DailyChecQ.CheckModules.FTPLastModified.Settings.FTPLastModifiedHandler"
        allowLocation="true"
        allowDefinition="Everywhere"
      />
    </sectionGroup>
  </configSections>
  <FTPLastModifiedGroup>
    <FTPLastModified enabled="true">
    </FTPLastModified>
  </FTPLastModifiedGroup>
</configuration>

正在加载导致错误的配置

FTPLastModifiedHandler config = (FTPLastModifiedHandler) ConfigurationManager.GetSection("FTPLastModifiedGroup/FTPLastModified");

---

这里缺少的是为处理配置节而配置的类型的程序集名称。如果未提供Assemblyname，.NET将在导致此问题的

System.Configuration

assembly中查找该类

<configuration>
  <configSections>
    <sectionGroup name="FTPLastModifiedGroup">
      <section name="FTPLastModified"
         type="DailyChecQ.CheckModules.FTPLastModified.Settings.FTPLastModifiedHandler, 
              {{YourAssemblyName}}"
        allowLocation="true"
        allowDefinition="Everywhere"
      />
    </sectionGroup>
  </configSections>
  <FTPLastModifiedGroup>
    <FTPLastModified enabled="true">
    </FTPLastModified>
  </FTPLastModifiedGroup>
</configuration>

YourAssemblyName是定义类

FTPLastModifiedHandler

的程序集的名称。一旦进行此更改，问题将得到解决

<configuration>
  <configSections>
    <sectionGroup name="FTPLastModifiedGroup">
      <section name="FTPLastModified"
         type="DailyChecQ.CheckModules.FTPLastModified.Settings.FTPLastModifiedHandler, 
              {{YourAssemblyName}}"
        allowLocation="true"
        allowDefinition="Everywhere"
      />
    </sectionGroup>
  </configSections>
  <FTPLastModifiedGroup>
    <FTPLastModified enabled="true">
    </FTPLastModified>
  </FTPLastModifiedGroup>
</configuration>
