SharePoint site theming: CSOM development

  • 아티클

The SharePoint client-side object model (CSOM) provides access to the SharePoint object model from code that is running locally or on a different server than SharePoint.

Prerequisites

Before you get started, make sure that you're familiar with the following:

You also need to reference the Microsoft.SharePointOnline.CSOM NuGet package (version 16.1.6906.1200 or later).

CSOM code example

The following example shows how to create a Microsoft.Online.SharePoint.TenantAdministration.Tenant object and call the GetAllTenantThemes method to return a list of themes.

Note

  • The URL used to create the context object includes the -admin suffix because TenantAdministration methods work with the admin site.
  • Create a Tenant instance with the Tenant constructor, and then call the methods on that instance.
  • You can use the same approach to call other theme management methods.
using System.Security;
using Microsoft.SharePoint.Client;
using Microsoft.Online.SharePoint.TenantAdministration;
using Microsoft.Online.SharePoint.TenantManagement;

...

ClientContext ctx = new ClientContext("https://mysite-admin.sharepoint.com/");
var pwd = "mypassword";
var passWord = new SecureString();
foreach (char c in pwd.ToCharArray()) passWord.AppendChar(c);
ctx.Credentials = new SharePointOnlineCredentials("admin@mydomain.com", passWord);
Tenant tenant = new Tenant(ctx);
ClientObjectList<ThemeProperties> themes = tenant.GetAllTenantThemes();

Theme definition example

For methods that take a theme argument, the following code defines an SPOTheme class that you can use to create custom themes.

/// <summary> 
/// Properties defining a theme in SharePoint Online. 
/// </summary> 
public class SPOTheme 
{ 
    /// <summary> 
    /// Specifies the name of the theme. This must uniquely identify the theme. 
    /// </summary> 
    public string Name 
    { 
        get; private set; 
    } 
    /// <summary> 
    /// Specifies the palette of colors in the theme, as a dictionary of theme slot values. 
    /// </summary> 
    public IDictionary<String, String> Palette 
    { 
        get; private set; 
    } 
    /// <summary> 
    /// Specifies whether the theme is inverted, with a dark background and a light foreground. 
    /// </summary> 
    public bool IsInverted 
    { 
        get; private set; 
    } 
} 

Applying a theme

There's currently no supported CSOM API to programmatically apply a theme to a specific site. For information on applying custom themes to individual site collections see SharePoint site design and site script overview

Methods/properties of the Microsoft.Online.SharePoint.TenantAdministration.Tenant class

Use the following methods to customize the set of available themes for a SharePoint tenant administration site. You can add a new custom theme, update an existing theme, or delete a theme, and you can retrieve a specific theme or all themes. You can also hide or restore the default themes that come with SharePoint.
