      C# Code to Check the given number is Positive(+ve) or                                         

                                   negative(-ve)

A simple if condition makes it possible.Checking the given number is +ve or -ve is have only 3 to 6 lines of simple code. It is very easy to understand.Firstly create a new project or a website.the new form must have at least a Text box (for inputting the value),a submit button(to check the number -ve or not by clicking  the button) finally another Text box or a label for output the result.My final form looks like this.

Design for the program 

This form have One Text box for inputting the checking value named as "txtNumber",a submit button to execute the code for checking the number is positive or negative named as btnCheck  and the output will be printed in alabel named as lblResult the labels forecolor set as red

after creating the form just double click the button and write this code:

             private void btnCheck_Click(object sender, EventArgs e)

        {

            int inputNumber; //inyeger variable for storing the inputted value

             

            inputNumber = Convert.ToInt32 (txtNumber.Text ); //assign the inputted value to the    

                                                                                                   // variable'inputNumber'

            if (inputNumber >= 0)     // if the given number is greater than zero then the number is    

                                                     // positive

            {

                lblResult.Text = "The Nunber is Positive";  //print output in labelbox 'lblResult'

            }

            else  //else the number is negative

            {

                lblResult.Text = "The Number is Negative";  //print output in labelbox 'lblResult'

            }

        }
