以后回答问题请把代码贴完整。回答你一个问题，我还得手敲代码，你故意麻烦回答者，当然没人愿意搭理你了。

 using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Q694451
{
    class DescriptionAttribute : Attribute
    {
        public string Description { get; set; }
        public DescriptionAttribute(string s) { Description = s; }
    }

    class DataFileAttribute : Attribute
    {
        public string FieldName { get; set; }
        public string FieldType { get; set; }
        public DataFileAttribute(string s, string t) { FieldName = s; FieldType = t; }
    }

    class ModelCustomer
    { 
        [DataFileAttribute("a", "nvchar")]
        [Description("a")]
        public string a { get; set; }
        [DataFileAttribute("b", "nvchar")]
        [Description("b")]
        public string b { get; set; }
        [DataFileAttribute("c", "nvchar")]
        [Description("c")]
        public string c { get; set; }
        [DataFileAttribute("d", "nvchar")]
        [Description("d")]
        public string d { get; set; }
        [DataFileAttribute("CU-DESC1", "")]
        [Description("Customer Description 1")]
        public string CustomDescription1 { get; set; }
    }

    class Program
    {
        static void Main(string[] args)
        {
            var query = typeof(ModelCustomer).GetProperties().Select(x => new
            {
                k = (Attribute.GetCustomAttribute(x, typeof(DataFileAttribute)) as DataFileAttribute) ?? new DataFileAttribute("", ""),
                v = (Attribute.GetCustomAttribute(x, typeof(DescriptionAttribute)) as DescriptionAttribute) ?? new DescriptionAttribute("")
            }).Single(x => x.k.FieldName == "CU-DESC1").v.Description;
            Console.WriteLine(query);
        }
    }
}
