Get null in controller when implementing IEnumerable in ASP NET model
I want use foreach for list in C# in controller Create([FromBody] CardList cards). I get the error Type ‘WordStudy.Models.CardList’ can only be used in ‘foreach’ statements if it implements ‘IEnumerable’ or ‘IEnumerable’, or if it has a suitable ‘GetEnumerator’ method whose return type has a ‘Current’ property and a ‘MoveNext’ method. When I implemented IEnumerable in my class it gets null.
When I implement IEnumerable in class it doesn’t get data through fetch api
