Create a static class with static field/property like following:

public static class DataContainer
{
    public static Int32 ValueToShare;
}

use it in multiple forms like following:

    public void Form1_Method()
    {
        DataContainer.ValueToShare = 10;
    }

    public void Form2_Method()
    {
        MessageBox.Show(DataContainer.ValueToShare.ToString());
    }
