Get all site collections from tenant using Tenant.GetSiteProperties()

Question

Could someone help me with implementation of GetSiteProperties to get all site collections from tenant.

What value we need to pass as start index. According to Microsoft documentation it is
An integer that represents the start index of the list of deleted sites.

https://learn.microsoft.com/en-us/previous-versions/office/sharepoint-csom/dn174792(v=office.15)

could you please confirm how many sites this method returns in one go.
For my application it is returning around 400 sites in first run with startindex as 0, which is very less than actual sites on tenant. And it is failing for any other value of startindex.
Could you please let me know if any updates pushed by Microsoft for this method.

Hello @shraddha sawant ,

Welcome to Q&A Forum!

The snippet using the "Tenant.GetSiteProperties" method o retrieve the site collection from the SharePoint Online Tenant is as follow:

Tenant tenant = new Tenant(context);  
SPOSitePropertiesEnumerable siteProps = tenant.GetSiteProperties("0", true);  
context.Load(siteProps);  
context.ExecuteQuery();  
Console.WriteLine("Total Site Collections: " + siteProps.Count.ToString());  
foreach (var site in siteProps)  
{  
 Console.WriteLine(site.Title + "\t" + site.Template.ToString());  
}  

Disadvantage to this method is, it won’t return the Site Collections created on new modern site templates.

We have another method under Microsoft.Online.SharePoint.TenantAdministration namespace for retrieving all site collections created under SharePoint online Tenant is Tenant.GetSitePropertiesFromSharePoint. The snippet given below uses this method and retrieve the all Site Collections irrespective of any webtemplates.

var credentials = new SharePointOnlineCredentials(userName, password);  
ClientContext context = new ClientContext(siteUrl);  
context.Credentials = credentials;  
   
Tenant tenant = new Tenant(context);  
SPOSitePropertiesEnumerable siteProps = tenant.GetSitePropertiesFromSharePoint("0", true);  
context.Load(siteProps);  
context.ExecuteQuery();  
Console.WriteLine("Total Site Collections: " + siteProps.Count.ToString());  
foreach (var site in siteProps)  
{  
Console.WriteLine(site.Title +"\t"+ site.Template.ToString());  
}
