Generate random numbers in Lucky7 project using C#

I have problems when trying to generate random numbers in Visual C#.Net. What I am trying to do is after I declare the variable called randomslot1, randomslot2, and randomslot3 for Random, I can assign those three variables to each of 3 text box.

Here's the code for it:

Code:

// C# Code:
/// <summary>
/// This is the code for the button. Once pressed, the button that
/// was pressed will generate numbers to each of the text boxes.
/// // Note: This is just a test.
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
public void SlotSpin_Click(object sender, System.EventArgs e) {
    // A constant variable...
    const int maxnumber = 10;
    // Declare a random variable for each of the slots.
    Random randomslot1 = new Random(unchecked((int)DateTime.Now.Ticks));
    Random randomslot2 = new Random(unchecked((int)DateTime.Now.Ticks));
    Random randomslot3 = new Random(unchecked((int)DateTime.Now.Ticks));
    // Send each of those as string.
    randomslot1.ToString();
    randomslot2.ToString();
    randomslot3.ToString();
    // Send those numbers to each of the text box
    // with a maximum value of 10 each having a different value.
    Slot1.Text = (string)randomslot1.Next(maxnumber);
    Slot2.Text = (string)randomslot2.Next(maxnumber);
    Slot3.Text = (string)randomslot3.Next(maxnumber);
}

The compiler told me that I can't convert from int to string, and the .Net help told me that I need to provide my conversion runtime but I don't know the code for it...

// Send each of those as string.
randomslot1.ToString();
randomslot2.ToString();
randomslot3.ToString();

These lines are useless. They return a string and you don't save it anywhere. Just delete them.

You cannot simply cast the int to string. It's no string. How about this:

Slot1.Text = randomslot1.Next(maxnumber).ToString();
