Body
<p>Writing a web api project and one of the parameters (which is a json array) on my method is coming into the api null. The jquery I'm making the call with looks like this:</p> <pre><code><script> $(document).ready(function () { $('#btnSubmit').click(function () { var jsRequestAction = { appId: 'appName', custId: 'custId', oprId: 'oprId', businessProcess: 'Requisition', action: 'Approve', actionKeys: [ 'blah blah 1', 'blah blah 2', 'blah blah 3' ] }; $.ajax({ type: "POST", content: "json", url: "http://localhost/api/appName/custId/oprId", contentType: "application/json; charset=utf-8", data: JSON.stringify({ requestAction: jsRequestAction }) }); }); }); </script> </code></pre> <p>My web api method looks like this:</p> <pre><code>public IList<ResponseAction> ActionCounter(string appName, string custCode, string custUserName, RequestAction requestAction) { IList<ResponseAction> actionResponseList = new List<ResponseAction>(); var conn = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString); conn.Open(); try { foreach (string s in requestAction.actionKeys) { var command = new SqlCommand { CommandText = "Sql statement", Connection = conn }; command.ExecuteNonQuery(); var reply = new ResponseAction(); reply.responseActionKey = s; reply.responseMessage = "Success"; actionResponseList.Add(reply); } return actionResponseList; } finally { conn.Close(); conn.Dispose(); } } </code></pre> <p>RequestAction model:</p> <pre><code>public class RequestAction { public string appId { get; set; } public string custId { get; set; } public string oprId { get; set; } public string businessProcess { get; set; } public string action { get; set; } public string[] actionKeys { get; set; } public string actionKey { get; set; } } </code></pre> <p>When I debug, I step through the method and when I get to the foreach loop, I get a null object reference. Looking in my locals section, all my properties for requestAction are null. I have tried prefixing the object with the [FromBody] tag to no avail after reading a few related articles. Any help would be appreciated.</p>

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.
