This is a header send by client on file upload. But the problem is that I do not want to use default HttpRequest instance. All I need to get file name and file data. What is best way to parse this. The line index ? Regex ?

I have datetime field in the table in my database. How to assign that datetime in my local variable ?
i tried
DateTime createdDate;
createdDate = Convert.ToDateTime(result.GetString(1));
but didn't work.

What's the value in result.GetString(1)? Try pausing at this line and then see what the data is that's in there.

its the datetime field.
value is 2010-09-30 11:14:29.783
thanks

It sounds to me like there's a culture problem here. In other words, the format on the system doesn't match the format of data in the database.

yah. I have datetime field in the database. When i am retrieving using datareader, it is taking as string. I think there where the problem is? how to convert that data from the database in to the string value ?

System.InvalidCastException: Unable to cast object of type 'System.DateTime' to type 'System.String'.
this one is showing as error.
i declare the variable as datetime and string as well but it gave the same error in both. it seems since my datafield is datetime, it is having problem when i am extracting that datetime.

In what way did it not work?

Assuming that result is a data reader or an sql parameter:
DateTime dateTime = (DateTime)dataReader["columnName"]
or
DateTime dateTime = (DateTime)sqlParameter.Value;
Are the most correct answers. If the field allows null, check for DbNull.Value first.

ya i already tried this before but it gave the same error.

Do not use strings for date/times if you can avoid it, as it opens up a whole range of potential problems. Instead have a datetime field in the database, and a DateTime variable in your code; then do what Ennis said.
If you must use strings, make sure to use a universal format. More is here[^]

I dont think anyone of you understood my problem. Let me explain again.
I have a table as
CREATE TABLE [dbo].[tblTest](
[ID] [int] IDENTITY(1,1) NOT NULL,
[Date] [datetime] NULL )
Now I am retrieving that value :
DateTime createdDate;
SqlCommand command = new SqlCommand("SELECT ID,Date FROM tblTest WHERE ID = '1'", myConnection);
SqlDataReader result = command.ExecuteReader();
if (result.Read())
{
createdDate = result.GetString(1);
}
when i did this , it gave error.
System.InvalidCastException: Unable to cast object of type 'System.DateTime' to type 'System.String'.
so i declared createdDate as string and tried again. It gave the same error. So I thought its the problem when we are retrieving datetime field from the database. I tried this query in query analyzer, and it is working fine.
I even tried this:
createdDate =(DateTime)(result.GetString(1)); but same error.

Damn - I really should read these things through first. Basically, you are trying to read a datetime out as a string here. The code should read
if (!result.IsDBNull(1))
createdDate = result.GetDateTime(1);

thanks. it worked.

1: show this result(result.GetString(1));
2: the result fit to time of rule ;
3: String strTime = Convert.ToDateTime(the result fit to time of rule).ToString("yyyy-MM-dd")
4: DateTime dt = new DateTime();
dt = Convert.ToDateTime(the result);

Try:
DateTime.TryParseExact(....);
See MSDN for details.

Hi all! I'm writing an Interop wrapper and am wrapping a method that takes an array of objects as a parameter.
void WrappedMethod(object[,] values);
void MyWrapper<T>(T[,] values)
{
WrappedMethod(values);
}
I thought all ref types were also objects, so why can't I cast T[,] to object[,] ?
Thank you all for you time
Matt

Do this:
private void WrappedMethod(object[,] values)
{
}
private void MyWrapper<T>(T[,] values) where T:class
{
WrappedMethod(values);
}

Nice, Nish. +5
So this has something to do with the inferrable type. Why does adding the T:class modifier help...said another way, what are the non-convertable types that it's griping about?
Cheers.

Value types. The compiler can't know in advance that T won't be a value type.
