How can I get information from a datagridview to use in another form

Question

I am making a program in c# and I have a datagridview at Form1 and I have another datagridview on Form2. How can I get the selected cell from the datagridview that is in Form1 and use na as a variable in Form2or wanted to use the variable test in another Form

This is how I’m going to get the values of the cells in datagridview:

    if (dataGridViewEnviarDados.SelectedRows.Count > 0)
    {
     foreach (DataGridViewRow r in dataGridViewEnviarDados.SelectedRows)
     {
      string test = r.Cells[0].Value.ToString()
     }
    }
