WhiteSpaceTrimStringConverter Class

Converts a string to its canonical format.

Namespace:  System.Configuration
Assembly:  System.Configuration (in System.Configuration.dll)

public sealed class WhiteSpaceTrimStringConverter : ConfigurationConverterBase

This WhiteSpaceTrimStringConverter object converts between a configuration string value and its canonical representation. Canonical representation means that all white spaces are trimmed from the beginning and end of a string value.

The following code example shows how to apply WhiteSpaceTrimStringConverter to a custom string property FileName.

[ConfigurationProperty("fileName", DefaultValue="   default.txt  ")]
[TypeConverter(typeof(WhiteSpaceTrimStringConverter))]
public String FileName
{
    get
    {
        return (String)this["fileName"];
    }
    set
    {
        this["fileName"] = value;
    }
}

The following is a configuration excerpt used by the previous example.

<?xml version="1.0" encoding="utf-8"?>
<configuration>

  <configSections>
    <section name="CustomSection" 
      type="Samples.AspNet.CustomSection, 
      ConfigurationConverters, 
      Version=1.0.0.0, Culture=neutral, 
      PublicKeyToken=null" 
      allowDefinition="Everywhere" 
      allowExeDefinition="MachineToApplication" 
      restartOnExternalChanges="true" />
  </configSections>
    
  <CustomSection fileName="default.txt" maxIdleTime="90" timeDelay="infinite" cdStr="str0, str1" permission="Read" maxUsers="Infinite"/>

</configuration>
