The "using" block in c# only allows one resource unless the resources are of the same type. To use multiple resources they are nested or stacked
using (StreamWriter w1 = File.CreateText("W1")) using (StreamWriter w2 = File.CreateText("W2")) { // code here }
instead of
using (StreamWriter w1 = File.CreateText("W1")) { using (StreamWriter w2 = File.CreateText("W2")) { // code here } }
Depending on the number of resources, the "using" block nesting can quickly get out of hand.

Overall, I think the semicolon, multi-resource, aspect is more complex than the benefits it gives. Clearer code results from nesting the statements. Stephen
