I was looking for a quick and easy solution to export data from SQL into an Excel format from within my ASP.NET application. I came across a great video posted by Beth Massi on the asp.net website (Video #7 at the bottom at http://www.asp.net/learn/linq-videos/ ). Beth steps through creating the LINQ...

All day I was stumped on why there wasn't a simple way to grab the first object in a sequence other than using: .Take(1).Single Then I discovered the keyword First. I'm still a little puzzled as to why .Single would throw an exception if more than a single element would be returned. I can't really see...

I was running into an issue where one of my webmethods was taking a large amount of time to return a small set (5-10 objects). I was using LINQ to SQL. I noticed that the LINQ to SQL query was returning all of the rows. After looking into the table a bit further, I noticed that the table included some...

After some quick research, I came across a post by Darren Neimke that referenced Rick Strahl's post about LINQ to SQL and Serialization . For me, performing the first work-around and setting...

LINQ views the Image type in SQL Server as Binary. So, there are a few options that we have. We can either (a) modify our LINQ to SQL class and change the property to Byte() instead of Binary or we can (b) convert the Binary to an array. To do the latter, you can use a lambda expression to obtain the...

I've recently discovered that LINQ and VB can be confusing. I was attempting to pull the top 10 rows of a table where the column started with 'W'. You'd think after I typed that, I'd figure out the solution. That's not the case. Instead, I struggled. Here's what I originally came up with: Dim q = From...

I was looking to separate my LINQ to SQL data layer from the rest of my application. So, I decided to move the files to a class library. This way, when my application builds, all of my LINQ files are found in MyApp.DL or something similar. However, I wanted the class library to use the SQL connection...

It's actually pretty easy and user friendly to obtain the value of the identity column using LINQ. After you create your object and insert it on submit, you can call the identity column's property on your object. For instance: Dim db As New BlogDataContext() db.BlogPosts.InsertOnSubmit(MyPost) db.SubmitChanges...
