Example:
using (var connection = SqlConnection("DBConnectionString"))
{
C = A.SomeMethod();
}
Does Dapper open up a Connection to the Database in the example case even though there are no calls to the database?
Or is the connection only established when the connection is requested IE:
using (var connection = SqlConnection("DBConnectionString"))
{
C = context.Query("SELECT * FROM UserSecrets");
}

I'm new to C#.
I have a method that returns an object with the List of objects inside.
0 {{DapperRow, RecordedFormID = 'id1'}} object {Dapper.SqlMapper.DapperRow}
1 {{DapperRow, RecordedFormID = 'id2'}} object {Dapper.SqlMapper.DapperRow}
How can I get those ids as strings?
Here is a screenshot
You can use System.Linq namespace and do this:
yourObject.Select(x => x.RecordedFormID);

var ticketnumber = TempData["ticketId"] as Ticket;
ticketnumber.TicketId = model.TicketId;
db.SaveChanges();
HttpPostedFileBase file = Request.Files["ImageData"];
UploadRepository service = new UploadRepository();
int i = service.UploadImageInDataBase(file, model);
I have the value inside my tempdata but when i try to assign the value of it to the model value it doesnt save and even in debug it tells me the value hasnt changed so i just dont get what i am doing wrong.
You need to change the assignment:
From:
ticketnumber.TicketId = model.TicketId;
To:
model.TicketId = ticketnumber.TicketId;

How do I convert this the time the computer has been to sleep for (here called 'offTime') into an integer (in terms of minutes)?
`DateTime timeOnSleep = DateTime.Now;`
`Application.SetSuspendState(PowerState.Suspend, true, true);`
`DateTime timeOnWake = DateTime.Now;`
`System.TimeSpan offTime = timeOnWake - timeOnSleep;`
TimeSpan time = timeOnWake - timeOnSleep;
var hours = time.TotalHours;

I have connected to my database using Data Connection Server Explorer and the same is added to my web.config as well. Now can someone tell me how to query it?
Sure, you could do this:
using (SqlConnection c = new SqlConnection(ConfigurationManager.ConnectionStrings["key_of_element"]))
{
c.Open();
using (SqlCommand cmd = new SqlCommand("SELECT * FROM Table"))
{
var reader = cmd.ExecuteReader();
while (reader.Read())
{
// do something with the data
}
}
}
