RE: [NAnt-users] Testing if a value is an Int

Title: Testing if a value is an Int

You could use a custom function in VB (‘cause IsNumeric is more tricky in C#!).  Try something like:       <script language="VB" prefix="numeric-tasks" >         <code>             <![CDATA[                                 [Function("is-integer")]                 Public Shared Function IsInteger(ByVal test As  Object)                                         Return (IsNumeric(test) AndAlso CInt(test) = Val(test))                   End Function                 ]]>         </code>     </script>   Which you can then call by using               <task if=”${numeric-tasks::is-numeric(myproperty)}”>             </task>   Where “myproperty” is the name of the property you wish to evaluate.   Note this is types freehand, so may have typos in it.   HTH,   Bill   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Nau, Michael Sent: 09 January 2006 18:43 To: nant-users@lists.sourceforge.net Subject: [NAnt-users] Testing if a value is an Int   Is there a "clean" way to test if a property value is an integer? I've come up with a bit of a hack to accomplish this, but this raises an error in my build log (which shows up in my ccnet errors page…). Here's my hack: <property name="is.input.an.integer" value="${int::parse(input)}" failonerror="false"/>        <if test="${property::exists('is.input.an.integer')}">   <echo message="input is an integer"/>  </if> <ifnot test="${property::exists('is.input.an.integer')}">   <echo message="input is not an integer"/>  </ifnot> Thanks, -Mike
