Preserve the Sequence of Web Methods

Preserve the Sequence of Web Methods

The .NET Framework generates a service help page when accessing the asmx page for a Web service. This page lists the Web methods exposed by the Web service, but doesn’t list these methods in the order they appear in the source code. This tip describes a minor modification which keeps Web methods in source code sequence.

The service help page is generated by DefaultWsdlHelpGenerator.aspx in

\%WINDOWS%  Microsoft.NET    Framework      [version]        CONFIG

DefaultWsdlHelpGenerator.aspx uses a Hashtable to store the Web methods. Replace the Hashtable with a ListDictionary (in the System.Collections.Specialized namespace) as follows:

  1. Open DefaultWsdlHelpGenerator.aspx
  2. Search for ‘Hashtable methodsTable’ in the line which reads
    'Hashtable methodsTable = new Hashtable();'
  3. Change both occurrences of ‘Hashtable’ to:
  4. 'System.Collections.Specialized.ListDictionary' so that the line reads'System.Collections.Specialized.ListDictionary methodsTable = newSystem.Collections.Specialized.ListDictionary();'
  5. Save the file.

Every service help page will now list Web methods in source code sequence.
