首先要构建一个实体类，注意实体类的属性和数据的列要一一对应，否则会报错。
public class Animal
{
public string Name { get; set; }
public int Age { get; set; }
public int Weight { get; set; }
public string Color { get; set; }
}
根据实体类获取要插入的表结构
public static string GetProperty<T>(T t) { string str=String.Empty; StringBuilder sb = new StringBuilder(); if (t == null) { return str; } System.Reflection.PropertyInfo[] properties = t.GetType().GetProperties(); if (properties.Length <= 0) { return str; } foreach (System.Reflection.PropertyInfo info in properties) { sb.Append(string.Format("@{0},", info.Name)); } sb.Remove(sb.Length-1,1); return sb.ToString(); }
数据插入的方法：
public int InsertBatch<T>(IEnumerable<T> entities) { Type t = typeof(T); string sql = "insert into " + t.Name + " values ("+ClassHelper.GetProperty(entities.FirstOrDefault())+")"; using (System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection(ConnectionString)) { conn.Open(); int records = 0; using (var trans = conn.BeginTransaction()) { try { records = conn.Execute(sql, entities, trans, 30, CommandType.Text); } catch (DataException ex) { trans.Rollback(); throw ex; } trans.Commit(); } return records; } }
