Question

我收到的日期是2014年12月33日上午12:00:00，当时MySQL数据库中的日期是2014-03-22。谁能告诉我为什么它会回归一个奇怪的日子？我假设它与Convert Zero Datetime有关..但我不完全确定。

代码：

public MySqlDataReader readerDB(string strSelectStmnt)
{
    //initializing command
    var comm = new MySqlCommand(strSelectStmnt, conn);

    //datareader for reading values from table
    dr = comm.ExecuteReader();

    //return the information from that was gathered by the datareader
    return dr;
}

while (dr.Read())
{
    Console.WriteLine(Convert.ToString(dr.GetValue(0)));
    Console.WriteLine(Convert.ToString(dr.GetValue(1)));
    Console.WriteLine(Convert.ToString(dr.GetValue(2)));
}

我的连接字符串：

string MyConString = "Server=" + strIP + ";" +
                     "PORT=" + strPort + ";" +
                     "DATABASE=" + strDB + ";" +
                     "Persist Security Info=no;" +
                     "Convert Zero Datetime=True;" +
                     "username=" + strDBUID + ";" +
                     "password=" + strDBPWD + ";";

我的查询：

var dr = db.readerDB("SELECT `trial_1_end` , `trial_2_end` , `permanent_end` FROM " +
                      DataTable + " WHERE item_name= '"+ strTmpSubscription +
                      "' AND username='" + User + "'AND password='" + Password + "'");

我的结果（来自Console.WriteLine）：

31/1/0001 12:00:00 AM 31/1/0001 12:00:00 AM 33/22/2014 12:00:00 AM

解答：

    DateTime.ParseExact(dr.GetDateTime(0).ToString("dd/MM/yyyy"), "dd/MM/yyyy", null)

Answer 1

You can use the SqlDataReader method GetDateTime:

Console.WriteLine(dr.GetDateTime(0).ToString());

And you can as well give it your custom formatting like:

Console.WriteLine(dr.GetDateTime(0).ToString("dd/MM/yy H:mm:ss"));

MySQL返回错误的日期/时间
