我有以下代码
var section = new CustomConfigurationSection();
section.SectionInformation.Type = "System.Configuration.NameValueFileSectionHandler";
section.SectionInformation.SetRawXml(sectionXml);
configuration.Sections.Add(sectionName, section);
最后一行抛出:
ConfigurationErrorsException错误 发生了执行配置 监视器的部分处理程序。
内部异常:
无法识别的元素'屏幕'。 (线 1)(第1行)
CustomConfigurationSection的定义:
public class CustomConfigurationSection: ConfigurationSection
{
public CustomConfigurationSection()
{
}
}
configuration是自定义类的一个实例,它具有名为Sections的属性,其类型为“ConfigurationSectionCollection”。
sectionXml中传入的xml是:
<monitor>
<screens>
<screen>
<regions>
<region>
<labelCoordinates />
<startupApplication>Internet</startupApplication>
<color />
<width>426</width>
<height>266</height>
<x1>0</x1>
<x2>0</x2>
<y1>0</y1>
<y2>0</y2>
</region>
</regions>
<height>800</height>
<width>1280</width>
</screen>
<screen>
<regions />
<height>0</height>
<width>0</width>
</screen>
</screens>
</monitor>
我怎样才能让它发挥作用?

在查看您的示例后,我可以看到它无法正常工作的原因是您正在使用NameValueFileSectionHandler。如果我没记错的话,这只允许使用以下语法:
<YourSectionName>
<add key="monitor.region.x" value="0"/>
<YourSectionName>
基于您想要使用的xml,您可能需要完全实现config部分类。所以你会得到以下内容:
class ServiceResponseSection : ConfigurationSection
{
[ConfigurationProperty("ServiceResponses")]
[ConfigurationCollection(typeof(ServiceResponse), AddItemName = "addServiceResponse", RemoveItemName = "removeServiceResponse", ClearItemsName = "clearServiceResponses")]
public ServiceResponses ServiceResponses
{
get { return this["ServiceResponses"] as ServiceResponses; }
}
}
public class ServiceResponses : ConfigurationElementCollection
{
public override ConfigurationElementCollectionType CollectionType
{
get
{
return ConfigurationElementCollectionType.AddRemoveClearMap;
}
}
public ServiceResponse this[int index]
{
get
{
return (ServiceResponse)this.BaseGet(index);
}
set
{
if (this.BaseGet(index) != null)
{
this.BaseRemoveAt(index);
}
this.BaseAdd(index, value);
}
}
public new ServiceResponse this[string responseString]
{
get
{
return (ServiceResponse)this.BaseGet(responseString);
}
set
{
if (this.BaseGet(responseString) != null)
{
this.BaseRemoveAt(this.BaseIndexOf(this.BaseGet(responseString)));
}
this.BaseAdd(value);
}
}
public void Add(ServiceResponse ServiceResponse)
{
this.BaseAdd(ServiceResponse);
}
public void Clear()
{
this.BaseClear();
}
protected override ConfigurationElement CreateNewElement()
{
return new ServiceResponse();
}
protected override object GetElementKey(ConfigurationElement element)
{
return ((ServiceResponse)element).ResponseString;
}
public void Remove(ServiceResponse element)
{
BaseRemove(element.ResponseString);
}
public void Remove(string responseString)
{
BaseRemove(responseString);
}
public void RemoveAt(int index)
{
BaseRemoveAt(index);
}
}
public class ServiceResponse : ConfigurationElement
{
private int m_tryCount;
public ServiceResponse()
{
this.m_tryCount = 0;
}
[ConfigurationProperty("responseString")]
public string ResponseString
{
get { return (String)this["responseString"]; }
set { this["responseString"] = value; }
}
[ConfigurationProperty("matchWholeString")]
public bool MatchWholeString
{
get
{
return (bool)this["matchWholeString"];
}
set
{
this["matchWholeString"] = value.ToString();
}
}
[ConfigurationProperty("retryCount")]
public int RetryCount
{
get
{
return (int)this["retryCount"];
}
set
{
this["retryCount"] = value.ToString();
}
}
[ConfigurationProperty("failsProcess")]
public bool FailsProcess
{
get
{
return (bool)this["failsProcess"];
}
set
{
this["failsProcess"] = value.ToString();
}
}
public int TryCount
{
get { return this.m_tryCount; }
set { this.m_tryCount = value; }
}
public void Reset()
{
this.m_tryCount = 0;
}
}
然后使用xml,如下所示:
<ServiceResponseList>
<ServiceResponses>
<clearServiceResponses/>
<addServiceResponse responseString="API Server Login Error" matchWholeString="false" retryCount="5" failsProcess="false"/>
</ServiceResponses>
</ServiceResponseList>
重点是我正在使用一个集合(在你的例子中,你实际上有几个)。在该集合中是我代表的对象。因此,要让它解析你拥有的xml,你必须创建一个部分处理程序来匹配你正在使用的。
根据我的示例,您可能希望将xml更改为以下行:
<monitor>
<screens>
<screen height="800" width="1280">
<regions>
<region startupApplication="Internet" width="426" height="266" x1="0" x2="0" y1="0" y2="0"/>
</regions>
</screen>
</screens>
</monitor>
然后,您可以使用类似于我的示例的类。虽然你可能得到你想要的东西,但你需要使用其他配置项来让它以这种方式工作。
希望有所帮助。
