Bug in WhereAny()?

Oct 20, 2013 at 6:52 PM
This is my code:
string[] barcodes = new string[] {
"20011713",
"12312312"
};
var barCodeIntName="BarCode";
                var expressions = new List<Expression<Func<SPListItem, bool>>>();
                foreach (string bc in barcodes)
                    expressions.Add(srch => ((string)srch[barCodeIntName]) == bc);

                var caml = Camlex.Query().WhereAny(expressions).ToString();
The resulting caml value is the following:
<Where>  <Or>    <Eq>      <FieldRef Name="BarCode" />      <Value Type="Text">20011713</Value>    </Eq>    <Eq>      <FieldRef Name="BarCode" />      <Value Type="Text">20011713</Value>    </Eq>  </Or></Where>
Why it forgets about the 2nd value? Or perhaps I'm doing something wrong? The isues's happening with Camlex 3.1 and 3.5.

hi
this is because of how lazy expressions evaluation rules implemented in .Net 3.5 (as far as I remember it was changed in .Net 4) and most popular question. Check the following discussions for solution:

Hi,

It this question is so popular, then I think it would be a good idea to add link to these explanations to the section 9 enlisted on your samples page. Just to help people to get rid of possible confusions.
