    <p>I am having a problem with the following code. It uses the Facebook c# SDK. The problem is that I am pulling and printing a list of all of my friends work history. However, when this data isn't available I think it is causing a NullReferenceException. I have looked at a bunch of solutions online, but haven't found one that seems to work. Any help would be appreciated.</p> <pre><code>public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { var accessToken = "..."; var client = new FacebookClient(accessToken); dynamic myInfo = client.Get("me/friends", new { fields = "name,id,work" }); foreach (dynamic friend in myInfo) { foreach (dynamic work in myInfo.work) // &lt;---- here { Response.Write("Employer: " + work.employer.name + "&lt;br/&gt; Position:" + work.position.name + "&lt;br/&gt;&lt;br/&gt;"); } } } } </code></pre> <p>I have included the suggested edits but am now getting a different error: </p> <pre><code> namespace WebApplication1.Site { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { var accessToken = "xxx"; var client = new FacebookClient(accessToken); dynamic myInfo = client.Get("me/friends", new { fields = "name,id,work" }); foreach (dynamic friend in myInfo) { **foreach (dynamic work in friend.work ?? new[] { new { employer = new { name = string.Empty }, position = new { name = string.Empty } } })** { Response.Write("Employer: " + myInfo.work.employer.name); } } } } } </code></pre> <p>'System.Collections.Generic.KeyValuePair' does not contain a definition for 'work' on Line 21</p>

    1. COYou might want to check if work.employer is null before trying to access the name property. And likewise for the position name.

    2. COI noticed you are using dynamic with JSON and work may not exist instead of being null, try my second edit that uses the ?? operator with the anonymous type. Also remove the `if (friend.work == null)`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
