For .NET 4.5+ framework

add reference: System.Runtime.Caching

add using statement: using System.Runtime.Caching;

public string[] GetNames()
{ 
    var noms = System.Runtime.Caching.MemoryCache.Default["names"];
    if(noms == null) 
    {    
        noms = DB.GetNames();
        System.Runtime.Caching.MemoryCache.Default["names"] = noms; 
    }

    return ((string[])noms);
}

In the .NET Framework 3.5 and earlier versions, ASP.NET provided an in-memory cache implementation in the System.Web.Caching namespace. In previous versions of the .NET Framework, caching was available only in the System.Web namespace and therefore required a dependency on ASP.NET classes. In the .NET Framework 4, the System.Runtime.Caching namespace contains APIs that are designed for both Web and non-Web applications.
