The error "cannot convert ienumerable to redis value" occurs when you are trying to directly store an IEnumerable object into Redis. In Redis, all values must be serialized as one of its supported data types, such as strings, lists, sets, sorted sets, or hashes. However, an IEnumerable represents a collection of objects, which does not directly map to any of the Redis data types. The error is essentially the result of a type mismatch between the .NET IEnumerable and the native Redis values.
To resolve this issue, you should first convert your IEnumerable object into a suitable Redis data type format before storing it in Redis. You have several options for how to do this:
Remember to deserialize or convert the data back to its original form when retrieving it from Redis. Choose the approach that best fits your application's requirements and performance expectations.
