我花了幾個小時試圖確定是什麼導致我的自定義配置節失敗,但我似乎無法找到問題的根源。配置節設置不初始化

我得到一個錯誤:

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,我開始通過注意到我有一個字符串驗證器設置:

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; 
     } 
    } 

} 

我刪除了afServer上1個字符長度的字符串驗證器要求,並注意到afDatabase上發生錯誤。在我看來,這些值永遠不會被初始化,這就是爲什麼當afServer的最小長度爲1時,它會失敗,但通過刪除它,錯誤將落在afDatabase上。

這裏是我的 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>

在這一步,你得到了一個錯誤?試圖獲得價值,或者只是在運行時?......別的東西? –

試試這個

<configSections>  
    <section name="tankConfiguration" type="TankInventory.Configurations.TankConfigurationSection" 
    allowLocation="true" 
    allowDefinition="Everywhere" 
    /> 

 <tankConfiguration afServer ="Test123" afDatabase ="Test123" tankTemplate ="Test21345"/>>
