C＃DateTime误解 [英] c# DateTime Misunderstanding

问题描述

在OP下方的注释中，有一个私有对象DateTime（）{throw new NotImplementedException（）; } 溜进来。

In one of the comments below the OP mentions a private object DateTime() { throw new NotImplementedException(); } slipping in. It happens .

我有一个 DateTime SqlCe数据库中的字段。我希望添加创建行的时间，因此需要：

I have a DateTime field in a SqlCe database. I wish to add the time the row is created hence the need for:

DateTime now = DateTime.Now;

但是我得到的这个问题是，这是'一种无效的方法给定的上下文。
我猜测它与静态有关，也许我在非静态函数中使用了它？

However this issue i am getting is that this is 'a method which is not valid in the given context'. Im guessing its something to do with it being static and im using it in a non static function perhaps ?

只需在同一线程中提问

SqlParameter Created = new SqlParameter("@Created", SqlDbType.DateTime);
**Created.Value = DateTime.Now; <--- gives error DateTime() is method which is not valid in the given context**
SqlCeCommand mySQLCommand = dbCon.CreateCommand();
mySQLCommand.CommandText = "INSERT into table (Created) VALUES (@Created)";
mySQLCommand.Parameters.Add(vetCreated);
mySQLCommand.ExecuteNonQuery(); 

这似乎是一个合理的列表命令，用于添加 DateTime 到数据库？

Does this seem like a resonable list commands to add DateTime to the database?

推荐答案

在这一行：

mySQLCommand.Parameters.Add(vetCreated);

我不知道 vetCreated 是什么，但我想这是根据错误消息判断的方法。

I don't know what vetCreated is, but I suppose that it's a method judging by the error message.

您应该在此处使用参数对象 Created 代替。

You should use your parameter object Created there instead.
