DataTableToModelList实体类

public List<T> DataTableToModelList<T>(DataTable table)
        {
    
            List<T> list = new List<T>();
            T t = default(T);
            PropertyInfo[] propertypes = null;
            string tempName = string.Empty;
            foreach (DataRow row in table.Rows)
            {
    
                t = Activator.CreateInstance<T>();
                propertypes = t.GetType().GetProperties();
                foreach (PropertyInfo pro in propertypes)
                {
    
                    tempName = pro.Name;
                    if (table.Columns.Contains(tempName))
                    {
    
                        object value = row[tempName].ToString();
                        if (value.GetType() == typeof(System.DBNull))
                        {
    
                            value = null;
                        }
                        pro.SetValue(t, value, null);
                    }
                }
                list.Add(t);
            }
            return list;
        }

下边展示实际中的用法

public void GetData()
        {
    
        using (MySqlHelper helper = new MySqlHelper(conn))
                {
    
                List<Data> info= new List<Data>();
                DataSet ds = helper.ExecuteDataSet("select * from Data", CommandType.Text);
                info= DataTableToModelList<Data>(ds.Tables[0]);
                }
        }
public class Data
    {
    
        public string Name {
     get; set; }
        public int Id{
     get; set; }
    }

这样就实现了把Datatable转换为指定ModelList的过程，注意Table的字段要和ModelList的字段一样
