The name 'txtGetal1' does not exist in the current context

Here is my code:

namespace Week2Dag3
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
int getal1,getal2,som;
getal1 = Convert.ToInt16(txtgetal1.Text);
getal2 = Convert.ToInt16(txtgetal2.Text);

som = getal1 + getal2;

MessageBox.Show(Convert.ToString(som));

}
}

Solution 1

C# is case sensitive: the error refers to

The name 'txtGetal1' does not exist in the current context
The name 'txtGetal2' does not exist in the current context

but your code uses different names:

C#

getal1 = Convert.ToInt16(txtgetal1.Text);
getal2 = Convert.ToInt16(txtgetal2.Text);

Solution 2

Looks like a problem with upper/lower case of your textboxes names.

if textboxes names are 'txtGetal1' and 'txtGetal2' then you need the following code:

getal1 = Convert.ToInt16(txtGetal1.Text);
getal2 = Convert.ToInt16(txtGetal2.Text);

The Answer is below

This issue usually happen when the name of the property is not available in the deign properties name

Solution:

Step 1: Check the TextBox Name between your Design page and Code Behind
