Examples

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;
    }
}

<ConfigurationProperty("fileName", _
DefaultValue:="   default.txt  "), _
TypeConverter(GetType(WhiteSpaceTrimStringConverter))> _
Public Property FileName() As String
    Get
        Return CStr(Me("fileName"))
    End Get
    Set(ByVal value As String)
        Me("fileName") = value
    End Set
End Property

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>

Remarks

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.
