前言

项目中实例化的对象，对象中里面很有很多属性，有些是我们不需要的，有些是我们需要的，例如在下面的示例中：ID，CreateBy等属性在CB_Projects对象中是不需要的，在获取实例化对象属性名称的时候需要把这些属性过滤掉。UpdateProjectRequest是入参实例

1、定义实例化对象

using System;using System.Collections.Generic; namespace ServiceMe.Apps.Business.Common.DAL{         public partial class CB_Projects    {        public int ID { get; set; }        public string ProjectNumber { get; set; }        public string CimtasNumber { get; set; }        public string Root1 { get; set; }        public string Root2 { get; set; }        public string Fill1 { get; set; }        public string Fill2 { get; set; }        public string Fill3 { get; set; }        public string Fill4 { get; set; }        public string Fill5 { get; set; }        public string Fill6 { get; set; }        public Nullable<bool> IsDelete { get; set; }        public string JointNumber { get; set; }        public string OtherJoint { get; set; }        public string CreateBy { get; set; }        public Nullable<System.DateTime> CreateTime { get; set; }        public string ModifiedBy { get; set; }        public Nullable<System.DateTime> ModifiedTime { get; set; }    }} using System;using System.Collections.Generic;using System.Linq;using System.Web; namespace ServiceMe.Apps.Business.Common.Models.RequestModel{    /// <summary>    /// 修改项目请求参数    /// </summary>    public class UpdateProjectRequest    {        /// <summary>        /// 主键ID        /// </summary>        public int? ID { get; set; }         /// <summary>        /// 项目编号        /// </summary>        public string ProjectNumber { get; set; }         /// <summary>        /// 庆达西编号        /// </summary>        public string CimtasNumber { get; set; }         /// <summary>        /// root1        /// </summary>        public string Root1 { get; set; }         /// <summary>        /// Root2        /// </summary>        public string Root2 { get; set; }         /// <summary>        /// Fill1        /// </summary>        public string Fill1 { get; set; }         /// <summary>        /// Fill2        /// </summary>        public string Fill2 { get; set; }         /// <summary>        /// Fill3        /// </summary>        public string Fill3 { get; set; }         /// <summary>        /// Fill4        /// </summary>        public string Fill4 { get; set; }         /// <summary>        /// Fill5        /// </summary>        public string Fill5 { get; set; }         /// <summary>        /// Fill6        /// </summary>        public string Fill6 { get; set; }    }}

2、获取实例化对象的属性名称。

public static void Main(string[] args, [FromBody]UpdateProjectRequest req)       {           CB_Projects cbProjects = new CB_Projects()           {               ProjectNumber = req.ProjectNumber,               CimtasNumber = req.CimtasNumber,               Root1 = req.Root1,               Root2 = req.Root2,               Fill1 = req.Fill1,               Fill2 = req.Fill2,               Fill3 = req.Fill3,               Fill4 = req.Fill4,               Fill5 = req.Fill5,               Fill6 = req.Fill6,               ModifiedBy = req.UserAccount,               ModifiedTime = DateTime.Now           };           PropertyInfo[] propertyInfos = typeof(CB_Projects).GetProperties();           List<string> nameList = propertyInfos.Where(t => t.GetValue(cbProjects) != null && t.Name.ToUpper() != "ID").Select(t => t.Name).ToList();           string str = string.Join(",", nameList);           string[] strArray = str.Split(',');       }

3、结果。
