C# program to read number from textbox?
Start building a project in C#. Choose Windows Application. Drag 2 textboxes and a button on the default form. Set the name of the input textbox to txtX and the name of the output textbox to txtX2. You may set the text of the button to "run" or to "^2". Double click the button. The source code is displayed in editor. Type this:





txtX2.Text = Math.Pow( Convert.ToDouble(txtX.Text), 2).ToString();





where txtX is the name of the input textbox and txtX2 is the name of the output textbox.





After compiling, when you click on the button the result should appear in the output textbox
