Created an attachment (id=426128)
 --> (http://bugzilla.novell.com/attachment.cgi?id=426128)
sample program

User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64;
Trident/4.0; GTB6.6; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR

Setting a numerical value for "Control Propertie" using "Expression Builder"
causes an error.
It works fine in the case of strings.

<%$ AppSettings: appSettings_string %>
is worked.
<%$ AppSettings: appSettings_int %>
is not worked.

I'm going to attach a sample program.

Probably, it will be fixed if you modify line 88 in
"System.Web/System.Web.Compilation/AppSettingsExpressionBuilder.cs" as follows.

expressionArray[1] = new CodeTypeOfExpression(entry.DeclaringType);

Reproducible: Always

Steps to Reproduce:
1. Run the attached demo
2. Launch Default.aspx
3. Error
Actual Results:  
Server Error
