[.Net] 编译调试时正常，发布后无法正常运行

发现是发布后的程序找不到App.config文件

添加GetConfiguration(), 指定文件路径，可以解决问题：

private void SetConfig()
{
   try
   {
        Configuration config = GetConfiguration();//ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

        if (config.AppSettings.Settings["dbconnect_read"] != null && config.AppSettings.Settings["dbconnect_write"] != null)
        {
              _dbConnectStrRead = config.AppSettings.Settings["dbconnect_read"].Value;
              _dbConnectStrWrite = config.AppSettings.Settings["dbconnect_write"].Value;
              _dbContext = new DBContext(_dbConnectStrRead, _dbConnectStrWrite);
         }
    }
    catch (Exception ex)
    {
        _logger.Debug(ex.Message);
    }
}

private static Configuration GetConfiguration()
{
   string configFileName = string.Empty;

   try
   {
       ExeConfigurationFileMap configFileMap = new ExeConfigurationFileMap();
       var path = "./App.config";
       configFileMap.ExeConfigFilename = path;
       Configuration configObj = ConfigurationManager.OpenMappedExeConfiguration(configFileMap, ConfigurationUserLevel.None);

       return configObj;
    }
    catch (Exception ex)
    {
        throw ex;
    }
}
