.NET Framework Exception Filters


Example

Since C# 6.0 exceptions can be filtered using the when operator.

This is similar to using a simple if but does not unwind the stack if the condition inside the when is not met.

Example

try
{ 
  // ...
}
catch (Exception e) when (e.InnerException != null) // Any condition can go in here.
{
  // ...
}
