Array of Tuples

Q: How would use tuples in C# 4.0 to create an array of tuples containing various types of data (i.e. Employee Name, Employee ID#)?

A: Listed below is a sample code snippet to implement an array of tuples.

//Array of Tuples (i.e. EmpName, EmpIDNum)
Tuple[] EmpRecs =
{
Tuple.Create("Sam Nasr", 891),
Tuple.Create("Jim Smith", 358),
Tuple.Create("Lisa Jones", 962)
};

string FirstEmpName = EmpRecs[0].Item1;

string SecondEmpName = EmpRecs[1].Item1;
int SecondEmpIDNum = EmpRecs[1].Item2;

Special October Meeting

Stephen Toub from the Parallel Computing Platform team at Microsoft will be presenting at the Cleveland C#/VB.Net User Group on Thursday, October 29, 2009. Please note this meeting date is in addition to, not replacing, our regularly scheduled meeting every 4th Tuesday (October 27, 2009).

He will be travelling through our district the last week of October. He will be speaking at corporations during the day, and user groups in the evening. Stephen's goal is to get direct feedback from developers on the products he works on. Your questions and feedback help make .NET better!

Stephen will discuss concurrency and how .NET 4.0 simplifies parallel programming. This is one of the exciting things about .NET 4.0. With Moore’s Law breaking down, software developers need to be able to master multithreading and know how to develop concurrent applications. Historically, this has been very difficult. It’s hard to understand concurrency issues, hard to write good code, and hard to debug when race conditions and such do happen. With .NET 4.0, there are APIs and tools to make parallel programming much simpler.

If you would like to attend this special meeting, please send an e-mail to sam@clevelanddotnet.info with "RSVP" in the subject line.

Set the identity specification on a primary key

Q: I always used databases provided by Microsoft to practice on. Today I tried to create my own and ran into trouble. Problem is that I cannot set the identity specification on a primary key. The column properties show up as no and I cannot change it to yes. I’m using SQL Server Express 2005 on a Vista machine. Any thoughts?

A: . To change column properties, you must modify the table (right click table and select “Modify”). Select and highlight the column you want to change, then expand the “Identity Specification” in the “Column Properties” pane. Change the “Is Identity” property to “Yes”. Please note the change must be made to the “Is Identity” property, not the “Identity Specification”.
