public class User { public int ID { get; set; } public string Name { get; set; } } //对应数据库表: //User //字段:ID、Name
Then you may need to write a method to convert the DataTable into an entity object to facilitate DataTable.Rows to obtain and fill it. .
The following is a general method I wrote, share + record, easy to copy directly in the future ~
private static List<T> TableToEntity<T>(DataTable dt) where T : class,new() { Type type = typeof(T); List<T> list = new List<T>(); foreach (DataRow row in dt.Rows) { PropertyInfo[] pArray = type.GetProperties(); T entity = new T(); foreach (PropertyInfo p in pArray) { if (row[p.Name] is Int64) { p.SetValue(entity, Convert.ToInt32(row[p.Name]), null); continue; } p.SetValue(entity, row[p.Name], null); } list.Add(entity); } return list; } // 调用: List<User> userList = TableToEntity<User>(YourDataTable);
