ArgumentException “Value does not fall within the expected range” error using fields on SPListItem

Here’s a pointer that might save a few minutes (or hours!) of frustration if you hit the same problem as me.  I was trying to extract the column (field) values from an SPListItem.  Easy enough, you just use code like this:

public void ProcessItem(SPListItem item)
    string name = item.Name;
    string title = item.Title;
    int id = item.ID;
    // Do something else here

OK so far so good. I had this code within my project and ran it. As soon as it got the line where it assigns the name variable it threw an exception:

System.ArgumentException: Value does not fall within the expected range

I put a breakpoint in the function and ran it with the VS debugger attached to the W3WP process to hit the breakpoint.  I began to check the item object in Visual Studio, and tried out a few expressions:

  • item.Name and item.Title both threw the exception
  • item[“Name”] and item[“Title”] both threw the exception as well
  • item.ID and item[“ID”] returned the correct values
  • item.Fields.ContainsField(“Name”), item.Fields.ContainsField(“Title”) and item.Fields.ContainsField(“ID”) returned true
How weird.  The ID column was behaving like I expected, but Title and Name were not.  All three  fields were in the Fields property on the item, but I couldn’t extract their column values without getting the ArgumentException.  It took a while and a fair bit of chasing around on forums to figure this out.  What was happening is that my SPListItem objects were coming out of the results of a query in SharePoint, using an SPQuery object.  It turns out that this is the behaviour you see if you forget to include the columns that you want in the ViewFields property of SPQuery.  This property should have a list of FieldRef XML elements so I had to add elements like this:
<FieldRef Name=’Name’><FieldRef Name=’Title’>
Check the MSDN documentation for more information about using SPQuery and ViewFields.
