The error is not related to toDictonary method. That is perfect. The issue is that there is a cast error around (int)B.STRIKE, SKEW_A = (decimal)S.SKEW_A. Make sure these two variables (B.STRIKE and S.SKEW_A) are cast-able to int and decimal respectively.

Just curious. Why don't you use data picker like https://jqueryui.com/datepicker/

Why you want to use MTOM. Using basic http binding sufficient for this case.

using (var command = new SqlCommand("Select * From Order1", connection)) // Table doesn't exist.
            {
                var ds = new DataSet();
                var da = new SqlDataAdapter(command);
                da.Fill(ds);

                Console.WriteLine(ds.Tables.Count);
                Console.WriteLine(ds.Tables[0]);
            }

Wonde Tadesse 12-Feb-16 16:29pm View

This code won't execute. It never reach there.

Console.WriteLine(ds.Tables.Count);
Console.WriteLine(ds.Tables[0]);

Wonde Tadesse 12-Feb-16 16:25pm View

Your "Print Hello" query won't fill the DataSet. You just simply arguing here. The where you get exception.

Wonde Tadesse 12-Feb-16 16:15pm View

"You will end up with a DataSet where Tables.Count == 0, and your attempt to access the first table with ds5.Tables[0] will throw an exception."

NO!

You won't get exception as long as dapt.Fill(ds5) executed properly. I already said to many times. Why don't you try it.

Wonde Tadesse 12-Feb-16 16:05pm View

That what I was saying you confused with Table.Count vs Rows.Count. Let me rephrase it again. If a command does not return any rows, no tables are added to the DataSet, and no exception is raised. But there will be table schema with empty record. Which means you have a Table but no rows

Careful here.

A command may not return a record/rows based on the query, but there is still a schema of a table.E.g

Select * From Order Where Order ID = 1000. Mind you this may returnempty record/row, However you still have Order Table

Wonde Tadesse 12-Feb-16 15:52pm View

Back to square one. There is always be a Table(at least one) in DataSet as long as dapt.Fill(ds5) executed. Do you agree ?

Wonde Tadesse 12-Feb-16 15:47pm View

If that is the case then ds5.Tables.Count !=0 is same as ds.Tables[0] !=null since both always be true. In this case.

Wonde Tadesse 12-Feb-16 15:43pm View

It's always true as long as dapt.Fill(ds5) executed. I think you're mixing Tables.Count with Rows.Count

Wonde Tadesse 12-Feb-16 15:38pm View

Checking ds5.Tables[0] != null never be false. Having there doesn't harm though. Do you agree ?

Wonde Tadesse 12-Feb-16 15:30pm View

If you traverse the code as is and assuming that dapt.Fill(ds5) works properly then there is at least one table. That is what it won't throw exception.

Wonde Tadesse 12-Feb-16 15:23pm View

Not necessary. If DataSet doesn't contain any tables, dapt.Fill(ds5) will throw exception. Since it couldn't fill any tables. That's why I skip that condition. Try it before commenting.

Wonde Tadesse 12-Feb-16 14:18pm View

It seems an issue of SQL Server version 2005 and less. The DataContext needs differing entity connection to be passed in the constructor. Like ProfileDataContext dbLive = new ProfileDataContext(entityConnectionInstance) ...

OP indicated may be he doesn't know. I don't blame the OP, Since he asked as a question. I understand you don't feel like to test this issue, however from my experience, either in runtime/compile time, String.Concat 100% works with LINQ to Entities query.

Wonde Tadesse 7-Jun-12 21:18pm View

I don't expect such kind of suggestion from you. In any case LINQ to Entities supports String.Conact funtionality.

Wonde Tadesse 6-Jun-12 22:41pm View

I'm not trying to make superior or inferior the "+" operator and Concat. I'm recommending a way of good programming practice. Don't forget it's a recommendation/suggestion. If we can avoid such kind of coding style for such small code we will not forget for the larger one.

Things to do with smallest change of " ext. " + c.PhoneExt to string.Concat("ext.",c.PhoneExt).

Wonde Tadesse 6-Jun-12 22:16pm View

We know that the compiler will do that. However Good programming skill starts with smallest. Don't you think?

Wonde Tadesse 6-Jun-12 20:35pm View

You don't need to evaluate "if (this.checked == true){ ... }" Instead use "if(this.checked) { ...}"

Wonde Tadesse 6-Jun-12 20:21pm View

Instead of " ext. " + c.PhoneExt, please do string.Concat("ext.",c.PhoneExt). :)

You need to create them(either OnPageLoad or OnPageInit) because that how Asp.NET run time controls works. Remember Http is stateless.

Wonde Tadesse 6-Apr-12 21:57pm View

If you follow what I wrote as a solution, you'll get the concept easily. In addition, see my previous comment. It's quite simple. Cheers.

Wonde Tadesse 6-Apr-12 20:47pm View

Where are you calling AddHtmlGroups method ? o_O, OnPageLoad or OnPageInit.
Either you are passing parameter or not, the method has to be called OnPageLoad or OnPageInit. This is a must. However you may check the parameter is passed or not before calling the method. Simple if condition statement. Like

protected void Page_Load(object sender, EventArgs e)
{
if(ulnumber!=null || ulnumber>0) // And check the rest of the parameters
AddHtmlGroups(,,ulnumber);
}
