ADO执行事务

在工作中遇到，需要批量提交的。在sql2008以后有表变量定义，可以实现。但个人比较习惯用C#，就有下面代码，直接上代码。。。

using (SqlConnection conn = new SqlConnection(Conn.Connection))
{
conn.Open();
SqlCommand comm = new SqlCommand() { Connection = conn };
SqlTransaction tran = conn.BeginTransaction();
comm.Transaction = tran;
try
{
comm.CommandType = CommandType.StoredProcedure;
comm.CommandText = "tb_role_INSERT";
SqlParameter[] parms = new SqlParameter[] {
new SqlParameter {ParameterName="@code",Value=array[0].ToString(),SqlDbType=SqlDbType.NVarChar, Size = 100 },
new SqlParameter {ParameterName="@name",Value=array[1].ToString(),SqlDbType=SqlDbType.NVarChar, Size = 500 },
new SqlParameter {ParameterName="@remark",Value=array[2].ToString(),SqlDbType=SqlDbType.NText},
new SqlParameter {ParameterName="@create_time",Value=DateTime.Now,SqlDbType=SqlDbType.DateTime},
new SqlParameter {ParameterName="@create_user_id",Value=Lib.ReadCookie("UserID"),SqlDbType=SqlDbType.Int},
new SqlParameter {ParameterName="@is_active",Value=1,SqlDbType=SqlDbType.Int},
new SqlParameter {ParameterName="@manufacturer_id",Value=Lib.ReadCookie("ManuID"),SqlDbType=SqlDbType.Int},
new SqlParameter {ParameterName="@custid",Value=Lib.ReadCookie("CustID"),SqlDbType=SqlDbType.Int},
new SqlParameter{ParameterName="@tb_roleID",Direction=ParameterDirection.Output,SqlDbType=SqlDbType.Int},
};
comm.Parameters.AddRange(parms);
comm.ExecuteNonQuery();
int id = Convert.ToInt32(comm.Parameters["@tb_roleID"].Value);

ArrayList sqlList = GetRolePermissionList(id, array[7].ToString());
for (int i = 0; i < sqlList.Count; i++)
{
string str2 = sqlList[i].ToString();
if (str2.Trim().Length > 1)
{
comm.CommandType = CommandType.Text;
comm.CommandText = str2;
comm.ExecuteNonQuery();
}
}

tran.Commit();
}
catch (SqlException ex)
{
tran.Rollback();
messge = ex.Message;
}
}
