Dynamically Creating Sharepoint Content Type

In a scenario where you need to create Content Type in bunch, there comes the role of Dynamic Content types.

The following code snippet helps you in creating content type dynamically.

Code:

using System;using Microsoft.SharePoint;
namespace DynamicContentTypeConsole{ class Program { static void Main(string[] args) { string siteURL = "URL of Site"; using (SPSite objSPSite = new SPSite(siteURL))
{

using (SPWeb objSPWeb = objSPSite.OpenWeb()) { SPContentType objSPContentType = new SPContentType(
objSPWeb.AvailableContentTypes["ParentContentType"], objSPWeb.ContentTypes, "Dynamic Content Type");

// A Required Field // Create Site Column objSPWeb.Fields.Add("Dynamic Number Column", SPFieldType.Number, true);

SPFieldLink objSPFieldLink1 = new SPFieldLink(objSPWeb.Fields["Dynamic Number Column"]); objSPContentType.FieldLinks.Add(objSPFieldLink1);

// A required String Field // Create Site Column objSPWeb.Fields.Add("Dynamic String Column", SPFieldType.Text, true);

SPFieldLink objSPFieldLink2 = new SPFieldLink(objSPWeb.Fields["Dynamic String Column"]);

objSPContentType.FieldLinks.Add(objSPFieldLink2);

//A non-required Choice Field // Create Site Column objSPWeb.Fields.Add("Dynamic Choice Column", SPFieldType.Choice, false);

SPFieldChoice choicefield = (SPFieldChoice)objSPWeb.Fields["Dynamic Choice Column"];

// Add a group to the filed choicefield.Group = "Dynamic Group";

// Add choices choicefield.Choices.Add(string.Empty); choicefield.Choices.Add("Yes"); choicefield.Choices.Add("No");

// Set the default choice choicefield.DefaultValue = string.Empty; choicefield.Update();

SPFieldLink objSPFieldLink3 = new SPFieldLink(choicefield); objSPContentType.FieldLinks.Add(objSPFieldLink3);

objSPWeb.Fields.AddLookup("Dynamic Lookup Column", new Guid("GUIDofRemoteList"), false);

SPFieldLookup lookupfield = (SPFieldLookup)objSPWeb.Fields["Dynamic Lookup Column"];

// Set the remote field lookupfield.LookupField = "RemoteFieldName"; lookupfield.Update(); SPFieldLink objSPFieldLink4 = new SPFieldLink(lookupfield); objSPContentType.FieldLinks.Add(objSPFieldLink4);

objSPWeb.ContentTypes.Add(objSPContentType); objSPContentType.Update(); } } } }}

The code snippet is the Console Application, and is ready to use.
