C# with Linq XML

Question

I'm a newbie, could someone please help me what type is the "Parts", I am unable to find the correct type and hence can't return the object "Parts". Thanks

private ???? load_parts()
{
     var element = XElement.Load("xml/suras.xml");
     **var** Parts= from var in element.Descendants("part")
                 orderby var.Attribute("index").Value
                 select new  dictSuras
                 {
                     PartIndex = Convert.ToInt32(var.Attribute("index").Value),
                     PartPosition = Convert.ToInt32(var.Attribute("position").Value),
                     PartName = var.Attribute("name").Value
                 };

     return  Parts;
 }

You might also consider using the XAttribute explicit casting operators. For example, in doing so the line for PartIndex becomes: PartIndex = (int)var.Attribute("index"), which is not only less code, but the code that is gone was noisy ceremonial type code, what's left is IMO meaty. — devgeezer

Since you're selecting a new dictSuras, the return value is an IEnumerable<dictSuras>.

@saafh, a word of advice: I highly recommend you check out ReSharper. It's great for things like this. With a single keystroke, you can convert your var declaration to the "real" type (in this case, IEnumerable<dictSuras>. I find it a huge boon, and it's exceedingly popular.

Rather than an answer that gives the information the OP is looking for, I will give an answer that shows how to find it. It is easier for all of us I think.

In Visual Studio, if you mouse-over a variable, a tooltip is displayed that includes the variable's type. This is quite useful if you are like me and dislike var, as it lets you see at a glance what the actual type is.

+1, but it's useful if people aren't like you and do like var as well!
