前提：datatable里有值，数据库中有相应的表
一、list，string方法
List<string> lstSql = new List<string>();
for (int i = 0; i < dt.Rows.Count; i++)
{
string ticketNo = dt.Rows[i][“票号”].ToString();
string actualcollect = dt.Rows[i][“实收款”].ToString().Replace(“-“, “”);
string issueDate = Convert.ToDateTime(dt.Rows[i][“出票日期”].ToString()).ToString(“yyyy-MM-dd”).Replace(“-“, “”);
string refundCharge = dt.Rows[i][“退票手续费（航空公司）”].ToString();
string approvalStatus = dt.Rows[i][“审核状态”].ToString();
sql = “insert into CMB_Refund_TktNo_Ref(OnlineRecordTicketNo,Actualcollect,IssueDate,ApprovalStatus,RefundCharge)”
+ ” values(‘{0}’,'{1}’,'{2}’,'{3}’,'{4}’) “;
sql = string.Format(sql, ticketNo, actualcollect, issueDate, approvalStatus, refundCharge);
lstSql.Add(sql);
}
Hippo.ExecuteSqlTran(cmd);
lstSql.Clear();
执行方法
public static int ExecuteSqlTran(List<String> SQLStringList)
{
using (SqlConnection conn = new SqlConnection(connectionString))
{
conn.Open();
SqlCommand cmd = new SqlCommand { Connection = conn };
SqlTransaction tx = conn.BeginTransaction();
cmd.Transaction = tx;
try
{
int count = 0;
for (int n = 0; n < SQLStringList.Count; n++)
{
string strsql = SQLStringList[n];
if (strsql.Trim().Length > 1)
{
cmd.CommandText = strsql;
count += cmd.ExecuteNonQuery();
}
}
tx.Commit();
return count;
}
catch
{
tx.Rollback();
return 0;
}
}
}
二、
List<CommandInfo> cmd = new List<CommandInfo>();
for (int i = 0; i < dt.Rows.Count; i++)
{
StringBuilder strSqlConfig = new StringBuilder();
strSqlConfig.Append(“insert into CMB_Refund_TktNo_Ref(OnlineRecordTicketNo,Actualcollect,IssueDate,ApprovalStatus,RefundCharge)”
+ ” values(@Tno,@Actcol,@Isdate,@Status,@Charge) “);
try
{
SqlParameter[] paraConfig =
{
new SqlParameter(“@Tno”, SqlDbType.NVarChar, 10),
new SqlParameter(“@Actcol”, SqlDbType.Float),
new SqlParameter(“@Isdate”, SqlDbType.NVarChar, 8),
new SqlParameter(“@Status”, SqlDbType.NVarChar, 8),
new SqlParameter(“@Charge”, SqlDbType.Float)
};
paraConfig[0].Value = dt.Rows[i][“票号”].ToString();
paraConfig[1].Value = dt.Rows[i][“实收款”].ToString().Replace(“-“, “”);
paraConfig[2].Value =
Convert.ToDateTime(dt.Rows[i][“出票日期”].ToString()).ToString(“yyyy-MM-dd”).Replace(“-“, “”);
paraConfig[3].Value = dt.Rows[i][“审核状态”].ToString();
paraConfig[4].Value = dt.Rows[i][“退票手续费（航空公司）”].ToString();
cmd.Add(new CommandInfo(strSqlConfig.ToString(), paraConfig));
}
catch (Exception ex)
{
MessageBox.Show(“写入数据库时发生错误:{0}”, ex.Message);
return;
}
}
Hippo.ExecuteSqlTran(cmd);
cmd.Clear();
执行方法
public static int ExecuteSqlTran(List<CommandInfo> cmdList)
{
using (SqlConnection conn = new SqlConnection(connectionString))
{
conn.Open();
using (SqlTransaction trans = conn.BeginTransaction())
{
SqlCommand cmd = new SqlCommand();
try
{
int count = 0;
//循环
foreach (CommandInfo myDE in cmdList)
{
string cmdText = myDE.CommandText;
SqlParameter[] cmdParms = (SqlParameter[])myDE.Parameters;
PrepareCommand(cmd, conn, trans, cmdText, cmdParms);
if (myDE.EffentNextType == EffentNextType.WhenHaveContine || myDE.EffentNextType == EffentNextType.WhenNoHaveContine)
{
if (myDE.CommandText.ToLower().IndexOf(“count(“) == -1)
{
trans.Rollback();
return 0;
}
object obj = cmd.ExecuteScalar();
bool isHave = false;
if (obj == null && obj == DBNull.Value)
{
isHave = false;
}
isHave = Convert.ToInt32(obj) > 0;
if (myDE.EffentNextType == EffentNextType.WhenHaveContine && !isHave)
{
trans.Rollback();
return 0;
}
if (myDE.EffentNextType == EffentNextType.WhenNoHaveContine && isHave)
{
trans.Rollback();
return 0;
}
continue;
}
int val = cmd.ExecuteNonQuery();
count += val;
if (myDE.EffentNextType == EffentNextType.ExcuteEffectRows && val == 0)
{
trans.Rollback();
return 0;
}
cmd.Parameters.Clear();
}
trans.Commit();
return count;
}
catch
{
trans.Rollback();
throw;
}
}
}
}
