Check this. There are many ways to do this.
http://stackoverflow.com/questions/1559770/send-values-from-one-form-to-another-form-in-c-sharp-winforms-application[^]

If you are creating Windows Application:

Create Global Variable :
string studentName;

Form2 (Set variable''s value in code)
studentName = "Your Name";

Form1 (Get variable''s value)
textbox1.text = studentName;

refer following link Variable and Method Scope http://msdn.microsoft.com/en-us/library/ms973875.aspx[^]

Hope this helps !!

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

      private void button1_Click(object sender, EventArgs e)
      {
         Form2 ChildFrm = new Form2(this);
         ChildFrm.ShowDialog();
      }
   }

public partial class Form2 : Form
   {
      private Form1 ParentForm;
      public Form2(Form1 parentForm)
      {
         InitializeComponent();
         ParentForm = parentForm;
      }

      private void Form2_FormClosing(object sender, FormClosingEventArgs e)
      {
         ParentForm.Controls["ParentFormTextBox"].Text = ChildTextBox.Text;
      }
   }
