How to do pagination with C# driver

Hi,

We can read about pagination here Paginate the Results - MongoDB Atlas

How can we integrate this using C# driver?

Thanks
Sven

Hi Sven,

Are you trying to do pagination with the $search operator or just pagination in general?

If you are using LINQ, you can perform pagination using the Limit and Skip operations as seen here

With the Fluent API you can use Skip and Take commands as seen below

_myCollection.Find(x=> true).SortBy(o=>o.Id).Skip(pageNumber == null ? 0: (pageNumber-1) * itemsPerPage).Limit(itemsPerPage).ToListAsync();

Hope that helps!

Hi maximtimeclock Wrote to @Sven_Glockner ,

Ensure you have the MongoDB C# driver installed in your project.
Set up your MongoDB connection using the MongoClient class. Replace with your MongoDB connection string. Use the Find method with Limit and Skip to implement pagination. Here’s how you can structure your query.
Limit: Specifies the maximum number of documents to return per page.
Skip`: Skips a specified number of documents to implement offset for pagination.
Iterate through documents to process each page of results.
Adjust pageSize and pageNumber variables as needed to navigate through different pages.

Implement error handling for cases where the number of documents exceeds the page size, ensuring the correct number of documents are fetched and displayed.

Add sorting options using Sort in FindOptions.
Modify filter to include query conditions based on your requirements.
Adjust response format (e.g., returning specific fields, using strongly typed classes instead of BsonDocument).

Hi @Rishit_Bhatia

thanks for your reply. I’m trying to to do pagination with the $search operator as mentioned in the documentation I already posted.

Meanhwile, I got it working using the Skip and Limit operators.
