我创建了一个自定义配置部分,如下所示
<configSections>
</configSections>
<Tabs>
<Tab name="Dashboard" visibility="true" />
<Tab name="VirtualMachineRequest" visibility="true" />
<Tab name="SoftwareRequest" visibility="true" />
</Tabs>
自定义配置节处理程序
namespace EDaaS.Web.Helper
{
public class CustomConfigurationHandler : ConfigurationSection
{
[ConfigurationProperty("visibility",DefaultValue = "true",Isrequired = false)]
public Boolean Visibility
{
get
{
return (Boolean)this["visibility"];
}
set
{
this["visibility"] = value;
}
}
}
}
运行应用程序时抛出异常无法识别的配置部分选项卡.如何解决这个问题
解决方法
您需要编写一个
configuration handler来解析此自定义部分.然后在配置文件中注册此自定义处理程序：
<configSections>
<section name="mySection" type="MyNamespace.MySection,MyAssembly" />
</configSections>
<mySection>
<Tabs>
<Tab name="one" visibility="true"/>
<Tab name="two" visibility="true"/>
</Tabs>
</mySection>
现在让我们定义相应的配置部分：
public class MySection : ConfigurationSection
{
[ConfigurationProperty("Tabs",Options = ConfigurationPropertyOptions.Isrequired)]
public TabsCollection Tabs
{
get
{
return (TabsCollection)this["Tabs"];
}
}
}
[ConfigurationCollection(typeof(TabElement),AddItemName = "Tab")]
public class TabsCollection : ConfigurationElementCollection
{
protected override ConfigurationElement CreateNewElement()
{
return new TabElement();
}
protected override object GetElementKey(ConfigurationElement element)
{
if (element == null)
{
throw new ArgumentNullException("element");
}
return ((TabElement)element).Name;
}
}
public class TabElement : ConfigurationElement
{
[ConfigurationProperty("name",Isrequired = true,IsKey = true)]
public string Name
{
get { return (string)base["name"]; }
}
[ConfigurationProperty("visibility")]
public bool Visibility
{
get { return (bool)base["visibility"]; }
}
}
现在您可以访问设置：
var mySection = (MySection)ConfigurationManager.GetSection("mySection");
