c# - How to set attributes values using reflection

Question

I have a class decorated with a attribute ...[DataEntity("MESSAGE_STAGING", EnableCaching = true, CacheTimeout = 43200)]

for some requirement,I want to change this value MESSAGE_STAGING at run time to Test_Message_Staging.

What is the best possible way to achieve this?

Can I use reflection, or is there any other way to do this.

Please provide code samples.

Thanks SNA

I don't believe it's possible to set attributes using reflection - and even if it is, I'd encourage you not to do so.

Attributes should be used for metadata which is known at compile-time. If you want a more dynamic form of metadata, load it from a file or use app.config instead... or at least have some special "placeholder" values (like |DataDirectory| in a connection string) which can be resolved at execution time.
