Basically the web method signature should not be altered. It should be only of the form
public static string[] GetCompletionList(string prefixText, int count, string contextKey) { .... }Here prefixText = field value (on which the details has to be filtered) count = number of values to be returned in the array contextKey = the Column name on which the prefixText has to be applied. And moreover, if you want to pass more parameter to this web service - you have two options, 1. Pass using Session variables by enabling the Session in web method 2. You can append values to the contextKey with some delimitters and in the web method you can make use of a split function to read the parameters passed. Hope this helps you. Regards, Vengat -

Create a proxy of the webservice and then create an instance of that proxy class.
