public DateTime GetRandomDate()
{

DateTime from = new DateTime(1950, 1, 1);
DateTime to = new DateTime(2050, 12, 31);

TimeSpan range = new TimeSpan(to.Ticks - from.Ticks);
return from + new TimeSpan((long)(range.Ticks * rnd.NextDouble()));
}

Found correct solution..

So? Use the Random class:

private Random rand = new Random();
private void button1_Click(object sender, EventArgs e)
     {
     DateTime randomDate = new DateTime(rand.Next(1066, 2188), rand.Next(1, 13), rand.Next(1, 32));
     }

You will probably want to add some error checking, as this will throw an exception on 31st April and so forth, but otherwise it will generate a random date in the years 1066 to 2187 inclusive.

public DateTime GetRandomDate()
{

DateTime from = new DateTime(1950, 1, 1);
DateTime to = new DateTime(2050, 12, 31);

TimeSpan range = new TimeSpan(to.Ticks - from.Ticks);
return from + new TimeSpan((long)(range.Ticks * rnd.NextDouble()));
}

this is my function ..now its working correct..before that
i didnt give the representation new DateTime in this line

DateTime from = new DateTime(1950, 1, 1);

Sincerely there are 1000 solutions to this problem, you need to be more specific on what you want to achieve.

However do not forget http://tinyurl.com/6fnww4y[^]

One possible solution can be:

DateTime RandomDay()
    {
        DateTime start = new DateTime(1995, 1, 1);
        Random gen = new Random();
        int range = ((TimeSpan)(DateTime.Today - start)).Days;           
        return start.AddDays(gen.Next(range));
    }

Cheers!
