现在做的一个项目需要用到批量添加，但是封装的底层没有这个方法，所以自食其力，自己来写。我们用的是拼接sql字符串的方法来实现功能。
具体实现流程：首先将需要的数据存储到实体的list中，然后将这个list传给我们批量添加的方法。批量添加的方法首先应该打开数据库连接，然后开始进行sql字符串的拼接，拼接完成后，调用sqlhelper方法进行添加。
具体代码如下：
#region 批量添加实体 /// <summary> /// 批量添加实体 /// </summary> /// <param name="staffscores"></param> /// <returns></returns> public bool Insert(List<YzQueryStaffScoresEntity> staffscores) { //打开数据库连接 SQLHelper sqlHelper = new SQLHelper("data source=192.168.22.239;initial catalog=YzEvaluationSystem;persist security info=True;user id=sa;password=xxx;", true); StringBuilder sbSql = new StringBuilder(); //拼接字符串，添加方法 sbSql.Append("insert into YzQueryStaffScoresEntity(ID,StaffID,StaffName,WorkEfficiency,ProfessionalEthics,BusinessAbility,HonestyDiscipline,WorkPerformance,other1,other2,Number,TotalScores,IsUsed) values"); //循环实体list，进行拼接 if (staffscores.Count > 1) { for (int i = 0; i < staffscores.Count - 1; i++) { sbSql.Append("('" + staffscores[i].ID + "',"); sbSql.Append("'" + staffscores[i].StaffID + "',"); sbSql.Append("'" + staffscores[i].StaffName + "',"); sbSql.Append(staffscores[i].WorkEfficiency + ","); sbSql.Append(staffscores[i].ProfessionalEthics + ","); sbSql.Append(staffscores[i].BusinessAbility + ","); sbSql.Append(staffscores[i].HonestyDiscipline + ","); sbSql.Append(staffscores[i].WorkPerformance + ","); sbSql.Append(staffscores[i].other1 + ","); sbSql.Append(staffscores[i].other2 + ","); sbSql.Append(staffscores[i].Number + ","); sbSql.Append(staffscores[i].TotalScores + ","); sbSql.Append(1); sbSql.Append("),"); } sbSql.Append("('" + staffscores[staffscores.Count - 1].ID + "',"); sbSql.Append("'" + staffscores[staffscores.Count - 1].StaffID + "',"); sbSql.Append("'" + staffscores[staffscores.Count - 1].StaffName + "',"); sbSql.Append(staffscores[staffscores.Count - 1].WorkEfficiency + ","); sbSql.Append(staffscores[staffscores.Count - 1].ProfessionalEthics + ","); sbSql.Append(staffscores[staffscores.Count - 1].BusinessAbility + ","); sbSql.Append(staffscores[staffscores.Count - 1].HonestyDiscipline + ","); sbSql.Append(staffscores[staffscores.Count - 1].WorkPerformance + ","); sbSql.Append(staffscores[staffscores.Count - 1].other1 + ","); sbSql.Append(staffscores[staffscores.Count - 1].other2 + ","); sbSql.Append(staffscores[staffscores.Count - 1].Number + ","); sbSql.Append(staffscores[staffscores.Count - 1].TotalScores + ","); sbSql.Append(1); sbSql.Append(")"); } //调用sqlhelper方法进行添加。 int flag = sqlHelper.ExecuteNonQuery(sbSql.ToString(), System.Data.CommandType.Text); if (flag > 0) { return true; } else { return false; } } #endregion
