控制台应用程序的C＃设置文件

所以我想创建一个存储可以编辑的特定信息的文件，如：

（lvl2 = false）

So I want to make a file that stores specific information that can be edited like:
(lvl2 = false)

//Just imagine that the user just wanted to play level 2

if (lvl2 = false){
Console.Writeline("Sorry but you didn't unlock level 2 yet");

if (lvl2 = true){
Console.Writeline("You entered level 2...");
//Here the user gets redirected to level 2
}

所以我想到了一个设置文件。无论是XML还是普通项目>添加属性>配置文件方法都没关系，我只是不知道如何从中检索数据。



做什么如果我想从设置文件中检查lvl2 = true，我必须这样做吗？



感谢您的每一个有用答案。



我尝试过：



我试过

So I thought of a settingfile. It does not matter if its XML or just the normal project>add attribute>configurationfile method, I just don't get how to retrieve data from it.

What do I have to do if I want to check if lvl2 = true from the settingfile?

Thanks for every useful answer.

What I have tried:

I have tried

lvl1 = ConfigurationManager.AppSettings.Get("lvl1");

和

and

using System;
using System.Configuration;
using System.Collections.Specialized;

namespace ConConfig
{
    class Program
    {
        static void Main(string[] args)
        {
            string sAttr;

            // Read a particular key from the config file            
            sAttr = ConfigurationManager.AppSettings.Get("Key0");
            Console.WriteLine("The value of Key0: " + sAttr);

            // Read all the keys from the config file
            NameValueCollection sAll;
            sAll = ConfigurationManager.AppSettings;

            foreach (string s in sAll.AllKeys)
                Console.WriteLine("Key: " + s + " Value: " + sAll.Get(s));
           Console.ReadLine();
       }
    }
}

但它没有用，我得到的错误代码是在当前上下文中无法使用configurationManager与CS0103。我也搜索了互联网，但我没有得到解决方案。



这个似乎也没有解决问题，因为我收到属性不在的错误当前的背景。

But it did not work and I got the error code that configurationManager is not availible in the current context with CS0103. I also searched the internet but I didn't get a solution.

This one also does not seem to solve the problem since I get the error that Properties is not in the current context.

using System;
using System.Configuration;
using System.Collections.Specialized;

namespace ConConfig
{
    class Program
    {
        static void Main(string[] args)
        {
            if (Properties.Settings.Default.lvl2)
            {
                Console.WriteLine("Sorry but you didn't unlock level 2 yet");
            }
            else
            {
                Console.WriteLine("You entered level 2...");
            }

            Properties.Settings.Default.lvl2 = true;
            Properties.Settings.Default.Save();
        }
    }
}
