c#个人记录常用方法(更新中)
1.日期毫秒转换为标准的C#日期格式
//使用时,先将秒Convert.ToInt64,返回格式2015-2-10 14:03:33
public DateTime JavaTimeToC(long ltime)
{
long time_JAVA_Long = ltime;//java长整型日期，毫秒为单位
DateTime dt_1970 = new DateTime(, , );
long tricks_1970 = dt_1970.Ticks;//1970年1月1日刻度
long time_tricks = tricks_1970 + time_JAVA_Long * ;//日志日期刻度
DateTime dt = new DateTime(time_tricks, DateTimeKind.Unspecified).AddHours();//转化为DateTime
return dt;
}
2.带事务的数据库插入更新删除方法
public void DbOp(List<string> sqlNum, ref string error)
{
if (sqlNum.Count <= )
{
error = "sql语句为空,没有订单数据!";
return;
}
try
{
if (!string.IsNullOrEmpty(strDbConnection))//缺少数据库连接字符串
{
using (OracleConnection con = new OracleConnection(strDbConnection))
{
using (OracleCommand cmd = con.CreateCommand())
{
con.Open();
OracleTransaction trans = con.BeginTransaction();//开始事务
cmd.Transaction = trans;//设置事务
string[] sql = sqlNum.ToArray();
try
{ for (int i = ; i < sql.Length; i++)
{
cmd.CommandText = sql[i];
cmd.ExecuteNonQuery();
}
trans.Commit();//提交事务
}
catch (Exception ex)
{
error += ex;
trans.Rollback();//回滚
}
finally
{
con.Close();//始终关闭数据库连接
}
}
}
}
else
{
//缺少数据库连接字符串
error += "缺少数据库连接字符串";
}
}
catch (Exception ex)
{ error += ex;
}
}
3.数据库查询方法
public DataSet Query(string SQLString)
{
using (OracleConnection connection = new OracleConnection(strDbConnection))
{
DataSet ds = new DataSet();
try
{
connection.Open();
OracleDataAdapter command = new OracleDataAdapter(SQLString, connection);
command.Fill(ds, "ds");
}
catch (System.Data.OracleClient.OracleException ex)
{
throw new Exception(ex.Message);
}
finally
{
connection.Close();
}
return ds;
}
}
4.DataTime,转换为string类型
public string DateTimeChange(DateTime dt)
{
string strDT = dt.Year.ToString();
if (dt.Month.ToString().Length == )
{
strDT += "-0" + dt.Month.ToString();
}
else
{
strDT += "-" + dt.Month.ToString();
} if (dt.Day.ToString().Length == )
{
strDT += "-0" + dt.Day.ToString();
}
else
{
strDT += "-" + dt.Day.ToString();
} if (dt.Hour.ToString().Length == )
{
strDT += "" + dt.Hour.ToString();
}
else
{
strDT += " " + dt.Hour.ToString();
} if (dt.Minute.ToString().Length == )
{
strDT += ":0" + dt.Minute.ToString();
}
else
{
strDT += ":" + dt.Minute.ToString();
} if (dt.Second.ToString().Length == )
{
strDT += ":0" + dt.Second.ToString();
}
else
{
strDT += ":" + dt.Second.ToString();
}
return strDT;
}
5.写日志dll
//地址:http://files.cnblogs.com/files/valiant1882331/%E5%86%99%E6%97%A5%E5%BF%97.rar
//使用
Log.ClsLog lo = new Log.ClsLog();
lo.writelogtype("",);
lo.writelogtype("", ,"日志文件名称");
dll源代码
public class ClsLog
{
/// 不限定名称写日志主方法
/// <summary>
