以ItemNo构造类，进行举例运行。

GetValue获取值，有两个重载，一般使用的是两个参数的，第二个参数是如果选中的Model的属性是列表索引化的话，可以放索引值，不是索引化属性，则放null

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ceshitype{    class Program    {        static void Main(string[] args)        {            string[] colEName = { "ID", "Name", "Gender", "Age" };            var itemNo = new ItemNo() { ID = 1, Name = "one", Gender = "man", Age = 18 };            for (int i = 0; i < colEName.Length; i++)            {                object obj = null;                string value = "";                Type itemNoType = itemNo.GetType();//获取model类型，Type是个类，里面涉及到的东西很多                obj = itemNoType.GetProperty(colEName[i]).GetValue(itemNo, null);//GetProperty获取属性，还有一个是GetProperties获取所有属性                value = Convert.ToString(obj);//将obj                Console.WriteLine("ItemNo下:{0}的值为：{1},类型为{2}", colEName[i], value, itemNoType.GetProperty(colEName[i]).PropertyType);            }            Console.ReadKey();        }    }    public class ItemNo    {        public int ID { get; set; }        public string Name { get; set; }        public string Gender { get; set; }        public int Age { get; set; }    }}

官方例子中有给出索引属性的方式

using System;using System.Reflection;class Example{    public static void Main()    {        string test = "abcdefghijklmnopqrstuvwxyz";        // Get a PropertyInfo object representing the Chars property.        PropertyInfo pinfo = typeof(string).GetProperty("Chars");        // Show the first, seventh, and last letters        ShowIndividualCharacters(pinfo, test, 0, 6, test.Length - 1);        // Show the complete string.        Console.Write("The entire string: ");        for (int x = 0; x < test.Length; x++)        {            Console.Write(pinfo.GetValue(test, new Object[] {x}));        }        Console.WriteLine();    }    static void ShowIndividualCharacters(PropertyInfo pinfo,                                          object value,                                         params int[] indexes)    {       foreach (var index in indexes)           Console.WriteLine("Character in position {0,2}: '{1}'",                            index, pinfo.GetValue(value, new object[] { index }));       Console.WriteLine();                              }                                      }

 

参照着尝试了一下，如果在itemno类中增加个string TEST进行测试的话，会报参数计数不准确

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ceshitype{    class Program    {        static void Main(string[] args)        {            string[] colEName = { "ID", "Name", "Gender", "Age", "Test" };            var itemNo = new ItemNo() { ID = 1, Name = "one", Gender = "man", Age = 18, Test = "Test" };            int x = 0;            for (int i = 0; i < colEName.Length; i++)            {                object obj = null;                string value = "";                Type itemNoType = itemNo.GetType();                if (i==4)                {                    for (int j = 0; j < "Test".Length; j++)                    {                        obj = itemNoType.GetProperty(colEName[i]).GetValue(itemNo, new object[] { j });                    }                }                else                {                    obj = itemNoType.GetProperty(colEName[i]).GetValue(itemNo, null);                }                                value = Convert.ToString(obj);                Console.WriteLine("ItemNo下:{0}的值为：{1},类型为{2}", colEName[i], value, itemNoType.GetProperty(colEName[i]).PropertyType);            }            Console.ReadKey();        }    }    public class ItemNo    {        public int ID { get; set; }        public string Name { get; set; }        public string Gender { get; set; }        public int Age { get; set; }        public string Test { get; set; }    }}

 

下面这种和官方例子差不多的写法，倒是正常运行

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ceshitype{    class Program    {        static void Main(string[] args)        {            string[] colEName = { "ID", "Name", "Gender", "Age" };            var itemNo = new ItemNo() { ID = 1, Name = "one", Gender = "man", Age = 18 };            for (int i = 0; i < colEName.Length; i++)            {                object obj = null;                string value = "";                Type itemNoType = itemNo.GetType();                obj = itemNoType.GetProperty(colEName[i]).GetValue(itemNo, null);                value = Convert.ToString(obj);                Console.WriteLine("ItemNo下:{0}的值为：{1},类型为{2}", colEName[i], value, itemNoType.GetProperty(colEName[i]).PropertyType);            }            Console.WriteLine("************************");            string x = "Test";            Type type = x.GetType();            for (int i = 0; i < x.Length; i++)            {                Console.WriteLine( type.GetProperty("Chars").GetValue(x, new object[] {i }));            }            Console.ReadKey();        }    }    public class ItemNo    {        public int ID { get; set; }        public string Name { get; set; }        public string Gender { get; set; }        public int Age { get; set; }    }}

 

 

type.GetProperty("").GetValue(models[i], null);

标签类

public class Tag : ModelBase    {        public Tag()         {            SortID = 99;        }        /// 
        /// 产品标签名        /// 
        [Required(ErrorMessage = "标签名不能为空")]        public string Title { get; set; }        /// 
        /// 该标签是否显示        /// 
        public bool IsShow { get; set; }        /// 
        /// 排序，初始99        /// 
        public int SortID { get; set; }        public virtual ICollection
     
       ProductTags { get; set; }    }
     

var model=new Tag();

Type type = models[i].GetType();

 type.GetProperty("Title").GetValue(model, null);

根据属性名获取相应的值
