C# Multiple Row Delete

On the subject of the article;

In this article, I’ll talk about deleting multiple lines with the Entity Framework. You can also delete a batch of records. First, I find it useful to look at a single record deletion.

 

 

 

In the code here, we find the first record with the value of classidsof 3 and delete the record with the Remove method from our dB.So we’re deleting a student with classid 3. But I share his code as well what should I do if I want to delete all students with class id 3.

 

The firstordefault method is a method of bringing single record.
Where it finds all the results.To delete multiple records, we need to bring all the records to be deleted.
Then we delete multiple records with RemoveRange method instead of remove.
