IF Statement multiple conditions same statement

Question

Hey all  looking to reduce the code on my c  if statements as there are several repeating factors and was wondering if a trimmer solution is possible   I currently have 2 if statements that need to carry out an identical statement  however the only variable is an extra condition on an if statement when a checkbox is not checked  Im just wondering if there is a way to make it one statement or make the condition string variable  heres the compressed version of the code   if  checkbox checked          if  columnname    a  amp  amp  columnname    b  amp  amp  columnname    c               statement 1            else         if  columnname    a  amp  amp  columnname    b  amp  amp  columnname    c           amp  amp  columnname    A2               statement 1              Its like I need to run an if statement within the conditions of an if statement if that makes sense  like this psuedo form   if  columnname    a       amp  amp  columnname    b       amp  amp  columnname    c       amp  amp  if checkbox checked columnname    A2

How about maybe something like this       var condCheck1   new string    a   b   c        var condCheck2   new string    a   b   c   A2        if  condCheck1 Contains columnName   amp  amp   checkbox checked            statement 1     else if   condCheck2 Contains columnName             statment 2

I think agileguy has the correct answer  but I would like to add that for more difficult situations there are a couple of strategies I take to solve the problem   The first is to use a truth table   If you Google  truth table  you will run across some examples related directly to programming and computer science   Another strategy I take is to use an anonymous function to encapsulate common logic between various conditions   Create it right before the if block  then use it where needed   This seems to create code that is more readable and maintainable

if  checkbox checked  amp  amp  columnname    a  amp  amp  columnname    b  amp  amp  columnname    c               statement 1        else if  columnname    a  amp  amp  columnname    b  amp  amp  columnname    c           amp  amp  columnname    A2               statement 1          is one way to simplify a little

Pretty old question but check this for a more clustered way of checking conditions   private bool IsColumn string col  params string   names    gt  names Any n   gt  n    col     usage   private void CheckColumn          if  IsColumn ColName   Column A    Column B    Column C                 not A B C column

I always try to factor out complex boolean expressions into meaningful variables  you could probably think of better names based on what these columns are used for    bool notColumnsABC    columnname    a  amp  amp  columnname    b  amp  amp  columnname    c   bool notColumnA2OrBoxIsChecked     columnname    A2    checkbox checked     if     notColumnsABC       amp  amp  notColumnA2OrBoxIsChecked              statement 1

You could also do this if you think it s more clear   if  columnname    a     amp  amp  columnname    b     amp  amp  columnname    c      if  checkbox checked    columnname    A2              statement 1

Isn t this the same   if   checkbox checked    columnname    A2   amp  amp           columnname    a  amp  amp  columnname    b  amp  amp  columnname    c             statement 1
