copied!<p>If you don't want to manually maintain those DataLoadOptions, you could use the <a href="http://t4toolbox.codeplex.com" rel="nofollow">T4 Toolbox</a> to generate your L2S classes and customize the DataContext generator to build a DataLoadOptions property that you can assign to the DataContext LoadOptions property when you need it. That's what I did, and now, when I want to XML Serialize an object and all of it's descendants, I can.</p> <p>I added this code to the LinqToSqlDataContextTemplate.tt</p> <pre><code> /// <summary> /// Sets up a property that will allow loading of all child properties. /// This is done to make serializing and entire object graph easier. /// </summary> private void SetupChildLoading() { #> private DataLoadOptions loadAllChildrenOptions; public DataLoadOptions LoadAllChildrenOptions { get { if (loadAllChildrenOptions == null) { loadAllChildrenOptions = new DataLoadOptions(); <#+ this.PushIndent(" "); foreach (Table t in this.Database.Table) { for (int i = 0; i < t.Type.Items.Length; i++) { Association association = t.Type.Items[i] as Association; if (association != null) { if (association.AccessModifier == GeneratedTextTransformation.AccessModifier.Public && !association.IsForeignKey) { this.WriteLine("loadAllChildrenOptions.LoadWith<{0}>(Q => Q.{1});",t.Type.Name.ToString(),association.Member); } } } } this.PopIndent(); #> } return loadAllChildrenOptions; } } <#+ } </code></pre> <p>And in the TransformText method:</p> <pre><code> #region LoadOptions <#+ SetupChildLoading(); #> #endregion </code></pre>
