获取配置文件内容

之前一直不知道怎么读取配置文件内容的，看了挺多，什么放在appsetting.json这种文件啊，xml啊，等等等等。不仅配置麻烦，还要引入很多dll，我就取个值这么麻烦？

public static class ConfigManager
{
    private static readonly Dictionary<string, string> ConfigDictionary = new();

    public static void InitConfig(string filePath)
    {
        try
        {
            using (StreamReader sr = new StreamReader(filePath))
            {
                string line;
                while ((line = sr.ReadLine()) != null)
                {
                    if (line.StartsWith("#"))
                    {
                        continue;
                    }

                    var strArray = line.Split(" ");
                    if (strArray.Length != 2)
                    {
                        continue;
                    }
                    ConfigDictionary.TryAdd(strArray[0], strArray[1]);
                    
                    // Console.WriteLine(line);
                }
            }
        }
        catch (Exception e)
        {
            Console.WriteLine("The file could not be read:");
            Console.WriteLine(e.Message);
        }
    }

    public static string GetConfigValue(string key)
    {
        if (!ConfigDictionary.ContainsKey(key))
        {
            return "";
        }
        return ConfigDictionary[key];
    }
}

就是这样了。在InitConfig方法里传入文件路径初始化。GetConfigValue取值。
