How do i find out if a value exists in a table in sql compact edition

In C# i want to know if a value exists in a column within a table.  I can't find or figure out the syntax.  I think i am looking for a function that returns the number of rows if found, but i cant find that function for sql compact edition in the class SqlCeCommand.
Thanks,

See, you need to check for the DataReader.HasRows property.
Aftere execulting the SQLCommand you will be retrieving resultset. get the DataReader and check with the property mentioned

I tried DataReader.HasRows property and this doesn't work in sql compact edition, "unless you have active cursor", or something like that, (which i do not).  But following along those lines i found I just need to return   reader.Read().  If there is anything to read it will be true, else false.  So i think that will do it unless anybody else has a better way.

 On the other solution, i did not want to do anything that would cause an exception as part of my "normal" code.  

Thanks both for the help
