With C# 6.0, you can control exceptions with a conditional if. See below for an example:
Listing 1. Control Exceptions
try
{
//Code that creates an exception
}
catch (System.DllNotFoundException dllEx) if (version != 3.0)
{
// Conditional exception
}
In the example, an exception is thrown only if the value of the version variable is not equal to 3.0
