As is known, the same exception can be detonated in multiple ways, an example of this IOException that starts when there is a NetworkStream timeout or when the host of a TcpClient is disconnected. What I need is a way to get the error code of each of these scenarios to be able to act in the right way. Greetings
As you said, there are several types of exceptions depending on how they originate, you can have an IOException, SqlException ...
Some exceptions if they have a number that identifies them that can be obtained through their property number. An example of these is the SqlException that has a property called Number.
Other exceptions such as InvalidOperationException does not have the Number property, you can access its Message property to see the explanation of the exception.
I hope it serves you.
I do not know if you mean the Message property of the Exception class:
try{
//código donde puede saltar una excepción
catch (Exception e){
string error = e.Message;
}
