.Net DateTime cannot be saved to SQL Server DATETIME because of precision

I have a property on an class that is of the .Net type DateTime. It is attempting to save into a table in SQL Server 2008 with a type of DATETIME. I am receiving a Database Error when I attempt to save a new record to the table from my .Net service.
When I look at SQL Server Profiler and see the call to the Stored Procedure that saves to the table, the property is a string: '2014-09-04 23:08:18.0500000'. When I truncate this string to just milliseconds the Stored Procedure call succeeds. The conversion of my .Net DateTime property to this string all happens under the hood and I have no control over that.
I do not need the full precision that I am seeing in the string, but it is important to keep milliseconds. I would rather not change my table column to a data type of DATETIME2. How can I remove the extra precision from the .Net DateTime property?

DateTime dateTime;
dateTime.ToString("yyyy-MM-dd HH:mm:ss.fff");
Please have #Tanner reply and mark that as an answer if correct as I believe he is correct in his comment above. Be careful to check for NULL on DateTime as you cannot convert to formated string if no data exists.
Below explains the range of DATETIME field in SQL Server.

C# DateTime vs SQL Server Date - type in stored procedure

If I have a C# DateTime object and a column in SQL Server of type Date (not DateTime)
For a stored procedure that takes in the date time from C# do I have any option other than passing in the C# DateTime as a SQL Server DateTime or can I pass it in of type Date?

Define it as a DATE in your stored procedure
CREATE PROCEDURE dbo.YourProcedure (#FromDate DATE)
.....
and call it like this from C#:
yourSqlCmd.Parameters.Add("#FromDate", SqlDbType.Date);
yourSqlCmd.Parameters["#FromDate"].Value = yourDotNetDateTime.Date;

You could always use the DateTime.Date Property
Gets the date component of this instance.

Safe DateTime in a T-SQL INSERT statement

Been running in problem lately with using a DateTime in a T-SQL INSERT INTO statement. Work fine on one machine but might not work on another and I guess this has to do with locale settings.
So if I have DateTime variable what is the safe way of using that in a SqlStatement string that it will always work regardless on local system settings?
Thanks

Use parameterized INSERT query.
Most likely, your code is assembling the SQL command string. That also makes your code vulnerable to SQL Injection.

You should use parameterized query as Adrian suggested.
Another possibility is to use an ISO 8601 string representation like described here which is independent of locale settings.
That would look like:
20110921 15:20:00

Either you use parametrized command/stored procedures where you create a parameter of type DateTime in the stored and assign it from .net code when you call the stored (so .NET and SQL will know they are working with a datetime and will never confuse/swap day and month), or you include a specific command on top of your insert commands and then format all dataetime strings with this pattern, for example:
SET DATEFORMAT dmy;
SET DATEFORMAT (Transact-SQL)

How to convert SQL Server timestamp object to string

I need your help in small problem, I have a column (data type timestamp) in SQL Server 2008.
Now I want to show this timestamp value in ASP.Net C# app as string. Is there any way to do that?
I tried it using regular data fetching in ASP.Net but it produced System.byte[] as output rather than actual value. In SQL Server Management Studio values are represented as 0x000000000000B3C0.

One option is to change it to the Date, while getting from the database. Like:
SELECT timestamp = DATEDIFF(s, '19700101', yourTimestampColumn)
FROM yourTable

I don't know if i catch you, but in sql you can cast timestamp value to datetime then to varchar like this:
declare #val timestamp = 0x0000AAE200B29565
select cast(cast(#val as datetime) as varchar(max))

Getting DB Server DateTime in application

I am using Entity framework and have 1 field in database AddedDate that is DateTime and not null, so I need to pass DateTime value.
But the problem is I have to pass DB Server datetime. How can I manage in this sceario or how can I get DB Server datatime to pass this.
I need to some unique solution, because I am this on many forms.
Edit: I need DB server Datetime upon insertion/updation in my application so that I can pass to entity framework object.
Thanks

Since you are using entity framework, you can do something like this:
var dateQuery = yourDbContext.CreateQuery<DateTime>("CurrentDateTime() ");
DateTime dateFromSql = dateQuery .AsEnumerable().First();

In general, if you use the entity framework and you use DateTime in a field, it will automatically do the back/forth conversion for you, just the same way it does so for integers, doubles etc.
Unless you mean something special, i.e., a char[40] field that must be filled with a DateTime value of a particular format.

You can get database server date and time by running SELECT GETDATE()) script.
Consider you have a table with 4 colums - the first 3 being strings and the last datetime, You can solve your issue by issueing INSERT SQL like this:
INSERT INTO myTable VALUES ('x', 'y', 'z', SELECT GETDATE())

Can't you use a stored procedure so you can get DB server Datetime very easily.

Just use getdate() in your query. For example:
INSERT INTO your_table (AddedDate, ...other columns) VALUES (getdate(), ...other values)
This basically asks the server to insert its own current date into the field; there's no need for you to retrieve it locally.
