C# Code for Find Sum Of 2 Numbers (textbox)
it is very easy find sum of two numbers in C# .for adding 2 numbers in C# we have 3 textBoxes,3 Labels
and a Button.Firstly create a new project or a website in visual studio .insert 3 TextBoxes,3 Labels and a Button.select the first TextBox and change the name to textBoxFirstNumber,select the second TextBox and change the name to textBoxSecondNumber,select third TextBox and change the name to textBoxSum ,set labelboxes name as First Number,Second Number Sum approximately and set the name of Button as buttonFindSum.after that your form looks like this
this is my forms design in this the bottom textbox have the sum of 2 text boxes this will add by clicking sum button and print the result
after creating the page double click on Sum Button and type the following codes
C#shap Code
private void buttonFindSum_Click(object sender, EventArgs e)
{
int firstNumber, secondNumber, sum; // to save numbers
firstNumber = Convert.ToInt32(textBoxFirstNumber.Text); //saves the first number into the variable
secondNumber=Convert.ToInt32(textBoxSecondNumbe.Text ); //saves the second number into a
variable
sum = firstNumber + secondNumber; //add two numbers
textBoxSum.Text = sum.ToString(); // stores the sum to the third textbox(result),the variable sum is
in the datatype integer so we have to convert integer to string because the TextBox only accepts
string variables and data
}
We can simply write it
private void buttonFindSum_Click(object sender, EventArgs e)
{
textBoxSum.Text = (Convert.ToInt32(textBoxFirstNumber.Text ) +
Convert.ToInt32(textBoxSecondNumber.Text)).ToString();
Convert.ToInt32(textBoxSecondNumber.Text)).ToString();
