我花了几个小时试图确定是什么导致我的自定义配置节失败,但我似乎无法找到问题的根源。配置节设置不初始化
我得到一个错误:
An exception of type 'System.Configuration.ConfigurationErrorsException' occurred in System.Configuration.dll but was not handled in user code
Additional information: The value for the property 'afDatabase' is not valid. The error is: The string must be at least 1 characters long.
看着我的配置部分,我开始通过注意到我有一个字符串验证器设置:
配置CS
public class TankConfigurationSection : ConfigurationSection
{
[ConfigurationProperty("afServer", IsRequired = true)]
[StringValidator(InvalidCharacters = "[email protected]#$%^&*()[]{}/;'\"|\\", MinLength = 0, MaxLength = 60)]
public String AfServer
{
get
{
return (String)this["afServer"];
}
set
{
this["afServer"] = value;
}
}
[ConfigurationProperty("afDatabase", IsRequired = true)]
[StringValidator(InvalidCharacters = "[email protected]#$%^&*()[]{}/;'\"|\\", MinLength = 1, MaxLength = 60)]
public String AfDatabase
{
get
{
return (String)this["afDatabase"];
}
set
{
this["afDatabase"] = value;
}
}
[ConfigurationProperty("tankTemplate", IsRequired = true)]
[StringValidator(InvalidCharacters = "[email protected]#$%^&*()[]{}/;'\"|\\", MinLength = 1, MaxLength = 60)]
public String TankTemplate
{
get
{
return (String)this["tankTemplate"];
}
set
{
this["tankTemplate"] = value;
}
}
}
我删除了afServer上1个字符长度的字符串验证器要求,并注意到afDatabase上发生错误。在我看来,这些值永远不会被初始化,这就是为什么当afServer的最小长度为1时,它会失败,但通过删除它,错误将落在afDatabase上。
这里是我的 的web.config:
<configuration>
<!-- Configuration section-handler declaration area. -->
<configSections>
<sectionGroup name="tankConfigurationGroup">
<section
name="tankConfiguration"
type="TankInventory.Configurations.TankConfigurationSection"
allowLocation="true"
allowDefinition="Everywhere"
/>
</sectionGroup>
<!-- Other <section> and <sectionGroup> elements. -->
</configSections>
<!-- Configuration section settings area. -->
<tankConfigurationGroup>
<tankConfiguration afServer ="Test123" afDatabase ="Test123" tankTemplate ="Test21345" >
</tankConfiguration>
</tankConfigurationGroup>
</configuration>
