F # exception handling for multiple types of exceptions
I'm trying to catch exceptions based on the type of the exception, for example in C #, but I get a compiler error when I do the following:
This type test or downcast will always
in line | :? System.Exception as genericException ->
Can you not have multiple catch blocks in F #?
try
......
with
| :? System.AggregateException as aggregateException ->
for innerException in aggregateException.InnerExceptions do
log message
| :? System.Exception as genericException ->
log message

This is because it :? System.Exception as
is redundant and the code can be summarized as follows:
try
// ...
with
| :? System.AggregateException as aggregateException ->
for innerException in aggregateException.InnerExceptions do
log message
| genericException -> log message
See this answer for the following examples: How to catch any exception (System.Exception) without warning in F #?
