如何在 app.config 中创建自定义配置部分 [英] How to create custom config section in app.config

问题描述

我想在app.config文件中添加自定义的configsection如下

I want to add the custom configsection in the app.config file as follows

<Companies>
  <Company  name="" code=""/>
  <Company  name="" code=""/>
</Companies>

<Employees>
  <Employee name="" Des="" addr="" sal=""/>
  <Employee name="" Des="" addr="" sal=""/>
</Employeess>

<Departments>
  <Department Id="" Projects=""/>
</Departments>

<Projects>
  <Project Path=""/>
</Projects>

在部门部分，它指的是项目部分.

In the Department section it is referring to Projects section.

谁能告诉我怎么做?以及如何在我的代码中访问它?

Can anybody tell me way to do it? And how to access it in my code?

 public class RegisterCompaniesConfig : ConfigurationSection
    {
        public static RegisterCompaniesConfig GetConfig()
        {
            return (RegisterCompaniesConfig)System.Configuration.ConfigurationManager.GetSection("RegisterCompanies")?? new RegisterCompaniesConfig();
        } 
        [System.Configuration.ConfigurationProperty("Companies")]       
        public Companies Companies
        {
            get
            {
                object o = this["Companies"]; return o as Companies;
            }
        }
    } 

public class Companies : ConfigurationElementCollection
    {
        public Company this[int index] 
        { get { return base.BaseGet(index) as Company; } 
            set
            {
                if (base.BaseGet(index) != null)
                {
                    base.BaseRemoveAt(index);
                } 
                this.BaseAdd(index, value);
            } 
        } 

        protected override System.Configuration.ConfigurationElement CreateNewElement() 
        { return new Company(); 
        } 

        protected override object GetElementKey(System.Configuration.ConfigurationElement element)
        { return ((Company)element).Name; }
    } 



public class Company : ConfigurationElement
    {
        [ConfigurationProperty("name", IsRequired = true)]   
        public string Name { get { return this["name"] as string; } }

        [ConfigurationProperty("code", IsRequired = true)]        
        public string Code { get { return this["code"] as string; } }
    }
