VS2010 save array/collection data to a file while debugging

Question

Is there some way to save array/list/collection data to a file while debugging in VS2010?

For example, in this code:

var addressGraphs = from a in context.Addresses
                    where a.CountryRegion == "Canada"
                    select new { a, a.Contact };

foreach(var ag in addressGraphs) {
   Console.WriteLine("LastName: {0}, Addresses: {1}", ag.Contact.LastName.Trim(),
                     ag.Contact.Addresses.Count());



   foreach(var Address in ag.Contact.Addresses) {
      Console.WriteLine("...{0} {1}", Address.Street1, Address.City);
   }
}

I'd like to set a breakpoint on the first 'foreach' line and then save the data in 'addressGraph' to a file.

where 'a' contains fields such as:

   int addressID
   string Street1
   string City
   <Ect.>

and 'Contact' contains fields such as:

   string FirstName
   string LastName
   int contactID
   <Ect.>

I'd like the file to contain the values of each of the fields for each item in the collection.

I don't see an obvious way to do this. Is it possible?

Answer 1

When your breakpoint is hit, open up the Immediate window and use Tools.LogCommandWindowOutput to dump the output to a file:

>Tools.LogCommandWindowOutput c:\temp\temp.log
?addressGraphs
>Tools.LogCommandWindowOutput /off

Note: You can use Log which is an alias for Tools.LogCommandWindowOutput

Update: The > character is important. Also, the log alias is case sensitive. See screenshot:

I also encoutered such a question, but in VS2013. I have to save a content of array while debugging.

For example, I need to save a content of double array named "trimmedInput". I do so:

1. Open QuickWatch Window from Debug menu (Ctrl+D, Q).

2. Put your variable in Expression and push Recalculate Button

3. You'll see all the values. Now you could select them all (Ctrl+A) and copy (Ctrl+C).

4. Paste (Ctrl+V) them in your favorite editor. Notepad, for example. And use them.

That's the simples way that I know. Without additional efforts. Hope that my description helps you!

P.S. Sorry for non English interface on screenshots. All necessary information are written in the text.

Something similar is possible with this method:

I built an extension method that I use in all of my projects that is a general and more powerful ToString() method that shows the content of any object. I included the source code in this link: https://rapidshare.com/files/1791655092/FormatExtensions.cs

UPDATE: You just have to put FormatExtensions.cs in your project and change the Namespace of FormatExtensions to coincide to the base Namespace of your project. So when you are in your breakpoint you can type in your watch window: myCustomCollection.ToStringExtended()

And copy the output wherever you want

Answer 4

On Visual studio Gallery search for: Object Exporter Extension.
be aware: as far as I worked with, it has a bug that block you from exporting object once in a while.
