In this article, we will learn about ContentType deletion in Sharepoint 2013/Office 365 using CSOM. Below is the sample CSOM code to achieve the same.

ClientContext cc = new ClientContext(siteUrl);
cc.AuthenticationMode = ClientAuthenticationMode.Default;
cc.Credentials = new SharePointOnlineCredentials(userName, pwd);
Web web = cc.Web;

ContentTypeCollection contentTypes = web.ContentTypes;
cc.Load(contentTypes);
cc.ExecuteQuery();

foreach (var item in contentTypes)
{
if (item.StringId == “0x0101009189AB5D3D2647B580DFGT56F356FB2”)

{
item. DeleteObject();

web.Update();

cc.ExecuteQuery();

}
}
