如何理解类属性是List的东西 [英] How to understand class property is List of something

问题描述

大家好，

我有一个具有基本类型属性的类，并且还有像List<>这样的类型。这个代码：

Hi everyone,
I have a class which has primitive type properties and also has types like List<> of something.
At this code:

string[] colums = typeof(T).GetProperties().Select(c => c.Name).ToArray();
foreach (var col in colums)
{
 var tc=  typeof(C).GetProperties().Select(c => c.Name).ToArray();
 var tp = col.GetType();
 var value = typeof(T).GetProperty(col).GetValue(item, null) ?? string.Empty;

 

}

我可以得到像这样的值。但是当它是List<>我不能。有什么方法可以理解属性是List<>什么？

I can get the values like this.But when it is List<> i cant.Is there any way to understand if property is List<> of something?

大约一半是一个完整的控制台应用程序，可以做你想要的。

About half way down is a complete console app which should do what you want.

你可以获得以下类型的权利：

you can get type of propety with:

System.Reflection.PropertyInfo propertyInfo = typeof(ObjectName).GetProperty("propertyName");
Type type = propertyInfo .PropertyType;
