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(',');
}
