AvoidUsingEmptyCatchBlock

Severity Level: Warning

Description

Empty catch blocks are considered a poor design choice because any errors occurring in a try block cannot be handled.

How

Use Write-Error or throw statements within the catch block.

Example

Wrong

try
{
    1/0
}
catch [DivideByZeroException]
{
}

Correct

try
{
    1/0
}
catch [DivideByZeroException]
{
    Write-Error 'DivideByZeroException'
}

try
{
    1/0
}
catch [DivideByZeroException]
{
    throw 'DivideByZeroException'
}
