Is there way to catch multiple exceptions at once and without code duplication code example

Example 1: two exceptions same catch c#

try
{
// Code
}
catch (Exception ex) when (ex is ArbitraryType1 || ex is ArbitraryType2)
{
  throw;
}

Example 2: c# catch two exceptions in one block

catch (Exception ex)            
{                
    if (ex is FormatException || ex is OverflowException)
    {
        WebId = Guid.Empty;
        return;
    }

    throw;
}
