Question

I am probably totally missing the point here but….

How can I pass a ‘var’ into another method?

(I am using linq to load XML into an Enumerable list of objects).

I have differernt object types (with different fields), but the final step of my process is the same regardless of which object is being used.

XNamespace xmlns = ScehmaName;
var result = from e in XElement.Load(XMLDocumentLocation).Elements(xmlns + ElementName)
             select new Object1
             {
                 Field1 = (string)e.Element(xmlns + "field1"),
                 Field2 = (string)e.Element(xmlns + "field2")
             };

var result2 = Enumerable.Distinct(result);

This code will vary for the different type of XML files that will be processed. But I then want to iterate though the code to check for various issues:

foreach (var w in result2)
{
    if (w.CheckIT())
    {
        //do something
    }  
}

What I would love is the final step to be in a method in the base class, and I can pass the ‘var’ varible into it from each child class.

The type of w is Object1 (in the code as written above). You can find this yourself by hovering your mouse over the var keyword and seeing the tooltip that Visual Studio shows you.

It’s hard to tell from your question, but it sounds like the CheckIt method is defined on a base type of Object1. If it is you can write your method to check them as

protected void CheckAll<T>(IEnumerable<T> result) where T : <base type with CheckIt method>
{
    foreach(var w in result)
    {
        if(w.CheckIt())
        {
            // do something
        }
    }
}
