在配置文件中创建自定义部分

问题描述

我正在尝试在app.config文件中创建自定义部分

I am trying to create custom section in app.config file

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="BlogSettings" type="ConsoleApplication1.BlogSettings,
      ConsoleApplication1" />
  </configSections>
  <BlogSettings
    Price="10"
    title="BLACKswastik" />
</configuration>

C#代码:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Configuration;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string title = BlogSettings.Settings.Title;

            Console.WriteLine(title);
            Console.ReadKey();
        }
    }

    public class BlogSettings : ConfigurationSection
    {
        private static BlogSettings settings
          = ConfigurationManager.GetSection("BlogSettings") as BlogSettings;

        public static BlogSettings Settings
        {
            get
            {
                return settings;
            }
        }

        [ConfigurationProperty("Price"
          , DefaultValue = 20
          , IsRequired = false)]
        [IntegerValidator(MinValue = 1
          , MaxValue = 100)]
        public int Price
        {
            get { return (int)this["Price"]; }
            set { this["Price"] = value; }
        }


        [ConfigurationProperty("title"
          , IsRequired = true)]
        [StringValidator(InvalidCharacters = "  ~!@#$%^&*()[]{}/;’\"|\\"
          , MinLength = 1
          , MaxLength = 256)]
        public string Title
        {
            get { return (string)this["title"]; }
            set { this["title"] = value; }
        }
    }
}

但是当我运行这段代码时，我得到了这个错误:

but when I run this code I am getting this error:

请告诉我我做错了什么事.

Please suggest me whats wrong I am doing.

Phil Haack also has a great blog post Three easy steps to a custom configuration section that will give you a quick head-start into building your own custom config sections.

要设计自己的自定义部分，还有一个方便的工具(Visual Studio外接程序)，名为配置部分设计器这将使创建自己的自定义部分变得非常容易和简单，并使它建立所有必要的代码来处理该自定义部分.

To design your own custom section, there's also a handy tool (Visual Studio add-in) called Configuration Section Designer that will make it very easy and simple to create your own custom section and have it build up all the necessary code to handle that custom section.
