I've the following doubt. I'm trying to Initialize an SQLConnection variable in the following way:
using (SqlConnection cnn = new SqlConnection(_MyConnectionString))
{
if (cnn.State == ConnectionState.Closed)
cnn.Open();
using (SqlBulkCopy objBulkCopy = new SqlBulkCopy(cnn))
{
. . .
}
}
The code above is working OK. I just recently added the if condition after the first using. Without it at the momment to initialize the cnn variable (SQLConnection) I don't know why this variable was initialize with its state property as closed.
That's why I validate the state property and open it in case it's closed.
Based on it, I have the following questions:
Don't it should be Open at the momment to initialize the SQLConnection varaible?
Should I explicit close the SQlConnection now?
... or the using statement do this?
I hope you can help me whit this. Might be those questions are basic however, I haven't facing this.
SqlConnection does not open the connection until you call the Open method. This lets you set other properties on the object after you create it. Also it lets you create the connection object early then wait until it is needed before you open it.
As for closing, yes you should close and Dispose, however the "using" statement is a neat way of handling this as it calls the Dispose for you.

1. No, you will have to open the connection yourself. It is not opened automatically.
2. You don't need to close it explicitly if you are using a using statement.
3. Yes, the using statement will make sure that the connection is closed and disposed when leaving the using block.

Now, I see it. I was a little confused about this, because if I use the connectionString to initialize the SQLBulkcopy variable, it implicit open the connection to the DB.
