# Find a contact using a udef field

> Find a contact using a user-defined field

This example creates the criteria directly on the client and saves and executes the find in one call.

<Note>
  The code examples on this page use the nuget SOAP proxies, [SuperOffice.NetServer.Services][2].
</Note>

```csharp theme={null}
using SuperOffice;
using SuperOffice.CRM.Services;
using SuperOffice.CRM.ArchiveLists
using(SoSession.Authenticate( "SAL1", "" ))
{
  using(FindAgent agent = new FindAgent())
  {
    string[] fields = new string[1] { "contactUdef/SuperOffice:1" };
    ArchiveRestrictionInfo[] restrictions = agent.GetSpecifiedCriteriaInformationWithDefaults( "Criteria", "findcontact", "associate=12345", fields, null ).Restrictions;
    restrictions[0].Values = new string[1] { "s" };
    restrictions[0].IsActive = true
    FindResults find = agent.FindFromRestrictions( restrictions, "findcontact", 50, 0 );
    DumpResult( find.ArchiveColumns, find.ArchiveRows );
  }
}
```

<Note>
  [DumpResult()][1] is a private helper method that you can easily add to your code.
