Question

我有对象数组，如何将其包含到控制台？

我需要打印属性及其值。

#!/usr/bin/env python
# -*- coding: utf-8 -*-


from terminaltables import AsciiTable
table_data=[
['','a','b','c','d','e','f','g','h','i','j'],
['10','','','','♥','','','♥','','',''],
['9','','','','','','','','','',''],
['8','','','','','','','','','',''],
['7','♥','','','','','','','','','♥'],
['6','','','','','','','','','',''],
['5','','','','','','','','','',''],
['4','♠','','','','','','','','','♠'],
['3','','','','','','','','','',''],
['2','','','','','','','','','',''],
['1','','','♠','','','♠','','','',''],
]
table = AsciiTable(table_data)
table.inner_row_border = True
print table.table

我必须使用反射，但我不知道如何使用它。

Answer 1

您可以尝试：Console.WriteLine( string.Join(",", attrs) );

Answer 2

你需要使用反射。这是一个样本：

    static void Main(string[] args)
    {
        string obj1 = "a string";
        int obj2 = 12;
        DateTime obj3 = DateTime.Today;

        object[] obj_array = { obj1, obj2, obj3 };

        foreach (object obj in obj_array)
        {
            //Print value
            Console.WriteLine("Value: " + obj.ToString());

            //Print property names
            Console.WriteLine("Property Names:");
            foreach (PropertyInfo prop in obj.GetType().GetProperties())
            {
                Console.WriteLine(prop.Name);
            }
            Console.WriteLine();
        }
        Console.Read();
    }

编辑：抱歉，您可能想要检索对象本身的属性值。在这种情况下，这是另一个样本：

class Program
{
    static void Main(string[] args)
    {
        MyObject myobj = new MyObject("prop1", "prop2");
        object[] obj_array = { myobj };

        foreach (object obj in obj_array)
        {
            foreach (PropertyInfo property in obj.GetType().GetProperties())
            {
                Console.WriteLine("Property Name: " + property.Name);
                Console.WriteLine("Property Value: " + property.GetValue(obj));
            }
        }
        Console.Read();
    }
}
public class MyObject
{
    public string Property1 { get; set; }
    public string Property2 { get; set; }
    public MyObject(string p1, string p2)
    {
        Property1 = p1;
        Property2 = p2;
    }
}
