dotnet 从 app.config 中获取配置信息示例

dotnet 代码

// 配置信息类
public static class Config
    {
        // 获取 Configuration 对象
       static Configuration _config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

        public static string Token
        {
            get
            {
                // 根据 Key 读取 <add> 元素的 Value
                return _config.AppSettings.Settings["Token"].Value;

            }
        }

        public static string connectionString
        {
            get
            {
                return _config.AppSettings.Settings["connectionString"].Value;

            }
        }
        public static string filePath
        {
            get
            {
                return _config.AppSettings.Settings["filePath"].Value;

            }
        }
    }

app.config 中节点配置

// app.config
