DataTable转List<T>

类：

 public class ModelConvertHelper<T> where T : new()
    {
        public static List<T> ConvertToModel(DataTable dt)
        {
            List<T> ts = new List<T>();//定义集合
            //Type type = typeof(T);//获得此模型的类型
            foreach (DataRow dr in dt.Rows)
            {
                T t = new T();
                PropertyInfo[] propertys = t.GetType().GetProperties();//获取此模型的公共属性
                foreach (PropertyInfo pi in propertys)
                {
                    if (dt.Columns.Contains(pi.Name))
                    {
                        if (!pi.CanRead)
                        {
                            continue;
                        }
                        object value = dr[pi.Name];
                        if (value != DBNull.Value)
                        {
                            pi.SetValue(t, value, null);
                        }
                    }
                }
                ts.Add(t);
            }
            return ts;
        }
    }

调用示例：

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            DataTable dt = new DataTable();

            dt.Columns.Add(new System.Data.DataColumn("Code", typeof(string)));
            dt.Columns.Add(new System.Data.DataColumn("ChineseName", typeof(string)));
            dt.Columns.Add(new System.Data.DataColumn("UserApplicant", typeof(string)));
            dt.Columns.Add(new System.Data.DataColumn("Email", typeof(string)));
            dt.Columns.Add(new System.Data.DataColumn("CreateDate", typeof(string)));

            for (int i = 0; i < 100; i++)
            {
                DataRow dr = dt.NewRow();
                dr[0] = "0801";
                dr[1] = "赵孟蒙";
                dr[2] = "mengmeng.zhao";
                dr[3] = "[email protected]";
                dr[4] = DateTime.Now.ToString();
                dt.Rows.Add(dr);
            }

            List<person> list = ModelConvertHelper<person>.ConvertToModel(dt);
        }
    }

    public class person
    {
        public string Code { get; set; }
        public string ChineseName { get; set; }
        public string UserApplicant { get; set; }
        public string Email { get; set; }
        public string CreateDate { get; set; }
    }
}
