Using C#, we have the traditional control blocks.

The if-than-else is:

  if(boolean expression){
   ...
  }
  else if(boolean expression){
   ...
  } 
  else{
   ...
  }

The while and the do while are similar to many other languages:

  while(boolean expression){
   ...
  }

or we have:

  do{
   ...
  } while(boolean expression);

For the loop for better to look an simple sample:

 for(int = 0; i<10; i++){
  ...
 }

Something inside the block is indexed using the i that begins having the value zero and is incremented at each loop until to have the value 10 (excluded).

For the switch

 switch(i){
  case 0:
   DoSomething0();
  break;
  case 1:
   DoSomething1();
  break;
  default:
   ForOtherCases();
  break;
 }

C# has a foreach block that we will see, in details, when talking about databases. Soon.

For exception handling we have:

   try{
     ...
   }
   catch(SomeExeption e1){
     ...
   }
   finally{
     ...
   }

The basic operators are:

Arithmetics:           +
                        -
                        *      (for multiplication)
                        /      (for division)
                        %      (for remainder)

        Logics:        &&      (for AND)
                       ||      (for OR)
                        !      (for NOT)

       Concatenation:   +
       
       Increment:       ++     (unary)
       Decrement        --     (unary)

       Relational:      ==     (for EQUAL)
                        !=
                         <
                         >
                        <=
                        >=

       Assignement:      =

       Scapes:           \'  
                         \"
                         \\
                         \n     (for "new line")

      Comentaries:       //
                         /*      */
                         <!--   -->   (inside .XAML files)  

We can talk here also about arrays (sometimes the Class ArrayList can be a better option - we will talk about this soon). For array creation we can have, by example:

     int myArray = new int[4];

To include values:

     myArray[0] = 9;
     myArray[1] = 3;
     myArray[2] = 7;
     myArray[3] = 2;

or we can use:

     int myArray = {9,3,7,2};

We can use a loop for to read the values:

 ...
  for(int i=0;i<myArray.Length;i++){
    ...
  }
 ...

We will see samples of the use of all these "basics" at the lessons of this tutorials serie.
