Question

我有一个方法，旨在从OleDB填充PersonModel;

public IEnumerable<PeopleModel> GetPeopleDetails()
{
    var constr = ConfigurationManager.ConnectionStrings["dbfString"].ConnectionString;
    using (var dbfCon = new OleDbConnection(constr))
    {
        dbfCon.Open();
        using (var dbfCmd = dbfCon.CreateCommand())
        {
            dbfCmd.CommandText = "SELECT pp_firstname, pp_surname, pp_title, pp_compnm, pp_hmaddr1, pp_hmaddr2, pp_hmtown, pp_hmcounty, pp_hmpcode, pp_spouse, pp_children FROM people ORDERBY pp_surname";
            using (var myReader = dbfCmd.ExecuteReader())
            {
                var peopleList = new List<PeopleModel>();
                while (myReader.Read())
                {
                    var details = new PeopleModel
                    {
                        details.Firstname = myReader[0].ToString(),
                        details.Lastname = myReader[1].ToString(),
                        details.Title = myReader[2].ToString(),
                        details.Company = myReader[3].ToString(),
                        details.Addr1 = myReader[4].ToString(),
                        details.Addr2 = myReader[5].ToString(),
                        details.Town = myReader[6].ToString(),
                        details.County = myReader[7].ToString(),
                        details.Spouse = myReader[8].ToString(),
                        details.Children = myReader[9].ToString(),                            
                    };
                    peopleList.Add(details);
                }
                return peopleList;
            }
        }
    }
}

此代码与我用于填写公司详细信息的方法完全相同，这没有问题。这是我用来建立一个人的PeopleModel。

namespace SdcDatabase.Model
{
    public class PeopleModel
    {
        public string Firstname { get; set; }
        public string Lastname { get; set; }
        public string Title { get; set; }
        public string Company { get; set; }
        public string Addr1 { get; set; }
        public string Addr2 { get; set; }
        public string Town { get; set; }
        public string County { get; set; }
        public string Spouse { get; set; }
        public string Children { get; set; }
    }
}

虽然公司方法以前运行良好，但是当我在实现People代码后尝试构建项目时，我现在遇到以下错误：无法使用集合初始化程序初始化类型'PeopleModel'，因为它没有实现'System.Collections.IEnumerable'的

我真的处于失败的原因，因为它的工作方式几乎与公司相同。

在初始化程序的赋值中没有details.的语法正确：

var details = new PeopleModel
{
    Firstname = myReader[0].ToString(),
    Lastname = myReader[1].ToString(),
    Title = myReader[2].ToString(),
    Company = myReader[3].ToString(),
    Addr1 = myReader[4].ToString(),
    Addr2 = myReader[5].ToString(),
    Town = myReader[6].ToString(),
    County = myReader[7].ToString(),
    Spouse = myReader[8].ToString(),
    Children = myReader[9].ToString(),                            
};

无法使用集合初始值设定项初始化类型'PeopleModel'，因为它没有实现'System.Collections.IEnumerable'
