Generic Method for check if a object already esists

[Norbert]

Hello,

is there a way (generic) to check if a object already exists in the database?
example:

//Signature
public bool ObjectExists<T>( T entity );

//So when you generate a DbContext you have these possibilities...
If( dbContext.ObjectExists<MyDomainClassType>( MyDomainClassType concreteEntity ))
          return "Yes...!";

Now I have no ideas to do this in a generic way?! --> maybe you know?

Thank you in advance,
Norbert

Hello Norbert,

You can try using the TryGetObjectByKey<> context method as shown in the relevant documentation article.

Please let us know if this recommendation does not  fully fit to your needs.
