如何顯示從控制器獲取數據從流讀取器在C＃中的多個記錄＃

在控制器操作即時獲取多個記錄，即時通訊不能顯示在表中。此代碼適用於單個記錄，顯示不適用於多個記錄。如何爲多個記錄使用集合。如何顯示從控制器獲取數據從流讀取器在C＃中的多個記錄＃

      PIRDetailsViewModel binModel = new PIRDetailsViewModel(); 
      binModel.status = Convert.ToString(Encoding.UTF8.GetString(data).Substring(4)); 
      binModel.UpdatedTime = TimeZoneInfo.ConvertTimeFromUtc(Convert.ToDateTime(bin.timestamp), TimeZoneInfo.FindSystemTimeZoneById("India Standard Time")).ToString(); 
      model.Add(binModel); 
     }

您需要使用集合並將其綁定到模型。在視圖中，您必須使用綁定在模型中的集合並將其呈現爲網格/表格 –

你只有一個元素添加到您的模型。

只調用一次model.Add(binModel);

這就是你有你的觀點只有一個元素的原因。
