Question

How can I use try/catch/finally to make sure that the function will return value?

I’m reading cells from an Excel sheet. Sometimes the parsing operation is not always working. I need to return 0, if, for whichever reason the operation fails.

try
{
  //1. read cell value from excel file
  //2. get the value, convert it as string, and
  //3. return it 
}
catch {}
finally {}

Thanks for helping

You don’t need finally.

int retValue;

try
{    
    // do something
    retValue = something;
    return retValue;    
}
catch (ApplicationException ex) // or just Exception
{    
    return 0;    
}
