​
Parameters

​
ChangedCount<T>

public static int ChangedCount<T>(this IEnumerable<T> enumerable, bool checkGraph = false) where T : DbObservableObject
Returns a representing the number of objects in the enumerable that have changes.

Returns a if any in the has changes.

​
Parameters

  • enumerable IEnumerable<T>:
