Changetracker.entries old value equal new value
A specific question about ChangeTracker in Entity Framework Core!
changetracker.entries
returns a collection of ChangeEntry
objects, which represent the changes made to an entity. Each ChangeEntry
has properties like Entry
(the entity being changed), OriginalValue
(the original value of the property), and CurrentValue
(the new value of the property).
To check if the old value is equal to the new value, you can use the following LINQ query:
var equalEntries = changetracker.entries
.Where(e => e.OriginalValue == e.CurrentValue)
.ToList();
This will give you a list of ChangeEntry
objects where the old value is equal to the new value.
If you want to check if there are any entries where the old value is equal to the new value, you can use the Any
method:
bool areEqual = changetracker.entries.Any(e => e.OriginalValue == e.CurrentValue);
This will return a boolean value indicating whether there are any entries where the old value is equal to the new value.
