TimeSpanMinutesConverter Class

Note: This class is new in the .NET Framework version 2.0.

Converts a time span expressed in minutes.

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

public class TimeSpanMinutesConverter : ConfigurationConverterBase
public class TimeSpanMinutesConverter extends ConfigurationConverterBase
public class TimeSpanMinutesConverter extends ConfigurationConverterBase

This type, like all the other configuration converter types, converts strings found in the configuration file to and from the related strongly typed properties.

In particular, the TimeSpanMinutesConverter converts String minutes, assigned to a configuration property, to TimeSpan minutes and vice versa.

The TimeSpanMinutesConverter persists values of type long representing a number of minutes.

The following code example shows how to define a custom TimeSpanMinutesConverter type.

using System;
using System.Collections.Generic;
using System.Text;
using System.Configuration;
using System.Globalization;
using System.ComponentModel;


public sealed class CustomTimeSpanMinutesConverter :
    ConfigurationConverterBase
{
    internal bool ValidateType(object value, 
        Type expected)
    {
        bool result;

        if ((value != null) &&
            (value.GetType() != expected))
            result = false;
        else
            result = true;

        return result;
    

    public override bool CanConvertTo(
        ITypeDescriptorContext ctx, Type type)
    {
        return (type == typeof(string));
    

    public override bool CanConvertFrom(
        ITypeDescriptorContext ctx, Type type)
    {
        return (type == typeof(string));
    

    public override object ConvertTo(
        ITypeDescriptorContext ctx, CultureInfo ci,
        object value, Type type)
    {
        ValidateType(value, typeof(TimeSpan));

        long data = (long)(((TimeSpan)value).TotalMinutes);

        return data.ToString(CultureInfo.InvariantCulture);
    

    public override object ConvertFrom(
        ITypeDescriptorContext ctx, CultureInfo ci, object data)
    {

        long min = long.Parse((string)data,
            CultureInfo.InvariantCulture);

        return TimeSpan.FromMinutes((double)min);
    



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

<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>
