Tricky Top 5 Exception Handling in C# Interview Questions

Hello Developers, this is not a detailed article. Instead, this is just a list of few tricky questions on exception handling which you might have faced in so many interviews.

Can we use multiple finally blocks inside the exception handling c# method?

Yes, we can write the multiple finally blocks in exception handling c#. For every try block, there needs to be either a catch block or finally block.

try
{
    try
    {
    }
    catch() // more than one catch blocks allowed
    {
    }
    finally // allowed here too.
    {
    }
}
catch()
{
}
finally
{
}

Is it possible to keep finally inside a try block?

Yes, it is possible to keep finally inside a try block. An example of the same is shown above.

Is it possible to keep multiple catch blocks for a try block?

Yes, it is possible to have multiple catch blocks associated with a try block. However, only one catch block can ever handle an exception at a time. Also, we need to make sure the generic exception block is always at the end.

try
{
}
catch(ArgumentNullException ex)
{
}
catch(Exception ex)
{
}
finally
{
}

Can we write try block without catch block?

No, It’s not allowed to write a try block without a catch/finally block. You have to write one of either catch or finally with each try block. You will be prompt with a compilation error.

Can we write try block only with finally block in exception handling c#?

Yes, you can write a try block only with the finally block.

try
{
}
finally
{
}
