c# - app.config custom configuration - 'System.TypeInitializationException' -

-

i tried following instruction app.config custom configuration

however, got stuck. app.config code:

<?xml version="1.0" encoding="utf-8"?> <configuration>   <configsections>     <section name="configuration" type="dp.configuration, myassembly" />   </configsections>   <startup>        <supportedruntime version="v4.0" sku=".netframework,version=v4.5.2"/>   </startup>   <configuration       inputloc="c:\input"    /> </configuration>

here configuration class:

    using system.configuration;      namespace dp     {         public class configuration : configurationsection         {             private static readonly configuration settings = configurationmanager.getsection("configuration") configuration;          public static configuration settings         {                         {                 return settings;             }         }          [configurationproperty("inputloc", isrequired = true)]         [stringvalidator(invalidcharacters = "  ~!@#$%^&*()[]{}/;’\"|", minlength = 1, maxlength = 256)]         public string inputlocation         {             { return (string)this["inputloc"]; }             set { this["inputloc"] = value; }         }     } }

and when call inputfolder = clientconfiguration.settings.inputlocation; system.typeinitializationexception.

error code:

see question: configurationsection-stringvalidator-failing

it looks need add default value attribute in configurationproperty attribute, ie.

[configurationproperty("inputloc", isrequired = true, defaultvalue="something")]
