How to break out of the IF statement

Question

I have code like this   public void Method         if something                  some code         if something2                        now I should break from ifs and go to te code outside ifs               return               The code i want to go if the second if is true     I want to know if there is any possibility to go to that code after ifs without using any goto statement or extracting rest of the code to the other method   Update   Yes I know Else    But this code is farly long and should be runned IF the first IF is false and when first IF is true And second is false  so extracting method I think is best Idea

just want to add another variant to update this wonderful  how to  list  Though  It may be really useful in more complicated cases   try       if  something                  some code         if  something2                        throw new Exception  Weird-01                    now You will go to the catch statement                   if  something3                        throw new Exception  Weird-02                    now You will go to the catch statement                     some code         return          catch  Exception ex        Console WriteLine ex      you will get your Weird-01 or Weird-02 here      The code i want to go if the second or third if is true

This is a variation of something I learned several years back   Apparently  this is popular with C   developers   First off  I think I know why you want to break out of IF blocks   For me  I don t like a bunch of nested blocks because 1  it makes the code look messy and 2  it can be a pia to maintain if you have to move logic around   Consider a do while loop instead   public void Method         bool something   true  something2   false       do               if   something  break           if  something2  break         while  false       The do while loop is guaranteed to run only once just like an IF block thanks to the hardcoded false condition   When you want to exit early  just break

To answer your question   public void Method         while true           if something                          some code             if something2                                break                        return                    break               The code i want to go if the second if is true

Try adding a control variable   public void Method         bool doSomethingElse   true      if something                  some code         if  something2                        doSomethingElse   false                      if doSomethingElse                   The code i want to go if the second if is true

You can use a goto to drop past some code  In the example  if thing1 is true then the check for things2 is bypassed   if  something        do stuff        if  thing1             do thing1            goto SkipToEnd            if  thing2            do thing2          SkipToEnd      do thing3

In this case  insert a single else   public void Method         if something                   some code         if something2                           now I should break from ifs and go to te code outside ifs                   else return               The code i want to go if the second if is true     Generally  There is no break in an if else sequence  simply arrange your code correctly in if   if else   else clauses

Another way starting from c  7 0 would be using local functions  You could name the local function with a meaningful name  and call it directly before declaring it  for clarity   Here is your example rewritten   public void Method            Some code here     bool something   true  something2   true       DoSomething        void DoSomething                 if  something                          some code             if  something2                                   now I should break from ifs and go to te code outside ifs                 return                            return                          The code i want to go if the second if is true        More code here

I think I know why people would want this   Run stuff if all conditions are true  otherwise run other stuff   And the conditions are too complicated to put into one if   Just use a lambda   if  new Func lt bool gt       gt        if  something1                if  something2                        return true                      return false                do stuff

You can return only if  something2 or use else return   public void Method         if something                  some code         if something2                          now I should break from ifs and go to te code outside ifs                   if  something2     or else             return               The code i want to go if the second if is true
