类型参数对象的访问属性

Question

I am using the below code

 public static void SaveArrayAsCSV<T>(T[] arrayToSave, string fileName)
        {
            using (StreamWriter file = new StreamWriter(fileName))
            {
                foreach (T item in arrayToSave)
                {
                    //item.GetType().GetField("AccountName")
                    //item.GetType().GetProperty("AccountName")
                    file.WriteLine(item + ",");
                }
            }
        }

Here the item has property called AccountName ,

I tried to access it using

item.GetType().GetField("AccountName") //returns null
item.GetType().GetProperty("AccountName") //returns an  object, not able to spot the actual value in it

But both are not returning the values. But when I check using the quick watch I am able to see the property

您需要使用GetValue方法，请尝试以下操作：

var accountName = item.GetType().GetProperty("AccountName").GetValue(item);
