I want to make increment and decrement counter.
There are two buttons called X and Y. First press X and then press Y counter should increment.
First press Y and then press X counter should decrement.

I am not familiar with c#. So can anyone help me please ?? :(

By counters do you mean variables? Declare a variable in the form class.

int counterX = 0;
int counterY = 0;

Then double-click a button and there (in the Click event handler, but sounds a bit tech'ie) you put an incrementation statement.

counterX++; 
//or
counterY--;

Does it help ya? ;)

That is how you would need to do it is with two variables and either the post-decrement or post-increment operators.

Basically x++ means to increase x by one after evaluating x. Thus, x-- means after evaluating x to decrease x by one. If you place the ++ and -- before the variable names then the variables are incremented or decremented before they are evaluated.
