Contiguous Logging of Method ,Calling & Exit time

Question

Trying to log the time When Method is Called and When its completed its operation and return the values Exit Time.

this i am trying in N-tier architecture.Like

i. Service Layer
ii. Business layer
iii. Data Layer

Data Layer defined a Method A, which is consumers by the Bushiness layer method B. Business layer method B is Called by Service Layer method D.

the Log Will be Like

Service Method D Called At {Time Stamp}
Business Layer Method B Called At {Time Stamp}
Data Layer Method called at {Time Stamp}
Data Layer Returned Response at {Time Stamp} .Exiting 
Business Layered Received response from Data layer at {Time Stamp}. Exiting 
Service Layered Received exception from Business layer Method. at {Time Stamp}. Exiting 

Currently i passing a additional string builder object for this to maintain log and respective time . appending current scope and Time Stamp.

Can i automate this process by dependency injection , so i can avoid passing that extra string builder object.or there is better solution for this.

Answer 1

There are different approaches you can use to get the desired functionality.

One approach is interception as (for example) Unity provides (see http://msdn.microsoft.com/en-us/library/dn178466(v=pandp.30).aspx)

Another approach is to use some kind of aspects. See Postsharp for an example (http://www.postsharp.net/)
