Question

我是C＃自定义配置的新手。

我想做一个简单的例子。我试过这个：https://stackoverflow.com/a/14890095/6121574 但是，我这样访问配置文件：https://stackoverflow.com/a/25806445/6121574

现在我明白了 System.Configuration.dll中发生未处理的“System.Configuration.ConfigurationErrorsException”类型异常 ...无法加载文件或程序集My.Assembly

我的问题是：App.config文件中的My.Assembly是什么？如何使我的代码工作？

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



namespace My
{
    public class MyConfigSection : ConfigurationSection
    {
        [ConfigurationProperty("", IsRequired = true, IsDefaultCollection = true)]
        public MyConfigInstanceCollection Instances
        {
            get { return (MyConfigInstanceCollection)this[""]; }
            set { this[""] = value; }
        }
    }
    public class MyConfigInstanceCollection : ConfigurationElementCollection
    {
        protected override ConfigurationElement CreateNewElement()
        {
            return new MyConfigInstanceElement();
        }

        protected override object GetElementKey(ConfigurationElement element)
        {
            //set to whatever Element Property you want to use for a key
            return ((MyConfigInstanceElement)element).Name;
        }
    }

    public class MyConfigInstanceElement : ConfigurationElement
    {
        //Make sure to set IsKey=true for property exposed as the GetElementKey above
        [ConfigurationProperty("name", IsKey = true, IsRequired = true)]
        public string Name
        {
            get { return (string)base["name"]; }
            set { base["name"] = value; }
        }

        [ConfigurationProperty("code", IsRequired = true)]
        public string Code
        {
            get { return (string)base["code"]; }
            set { base["code"] = value; }
        }
    }

    class Program
    {


        static void Main(string[] args)
        {
            var config = ConfigurationManager.GetSection("registerCompanies")
                  as MyConfigSection;

            foreach (MyConfigInstanceElement e in config.Instances)
            {
                Console.WriteLine("Name: {0}, Code: {1}", e.Name, e.Code);
            }

        }
    }
}

我的App.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="registerCompanies"
             type="My.MyConfigSection, My.Assembly" />
  </configSections>
  <registerCompanies>
    <add name="Tata Motors" code="Tata"/>
    <add name="Honda Motors" code="Honda"/>
  </registerCompanies>
</configuration>

Answer 1

type属性的字符串的第一部分是类型本身，然后是包含该类型的程序集。

如果您的类型是Company.Project.Configuration.Settings，并且它保存在Company.Project.dll的程序集中，那么您将使用“Company.Project.Configuration.Settings，Company.Project”

Answer 2

如果项目名称是＆＃34;我的＆＃34;。它适用于此配置。 3个小时后，我找到了一个解决方案：）

 <?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section name="registerCompanies"
             type="My.MyConfigSection, My" />
  </configSections>
  <registerCompanies>
    <add name="Tata Motors" code="Tata"/>
    <add name="Honda Motors" code="Honda"/>
  </registerCompanies>
</configuration>

App.config自定义部分中的类型是什么
