[c#] random number generator between 0 - 1000 in c#

I need help in writing a program that will generate 100 random numbers between 0 and 1000. The out put needs to be displayed in a windows message box. i'm stuck as to what code I have use to get the numbers in the box and to only have 100 random numbers.

Use this:

static int RandomNumber(int min, int max)
{
    Random random = new Random(); return random.Next(min, max);

}

This is example for you to modify and use in your application.

Have you tried this

Random integer between 0 and 1000(1000 not included):

Random random = new Random();
int randomNumber = random.Next(0, 1000);

Loop it as many times you want
