C＃中的真错误测验

Question

I'm building a auto guiz generator in C# in which take the pdf file from user and generate MCQS Fill in the blanks and true false. I completed the two modules MCQS and Fill in the blanks but have the problem in generating true-false values in a random way.

So my problem is: how can i randomly generate true and false values?

Answer 1

public bool GetRandomBoolean(Random rnd)
{
    return rnd.Next(0, 2) == 0;
}

Edit : Note that you should not use this method in this way:

for(int i = 0; i < 1000; i++)
{
    bool randomBool = GetRandomBoolean(new Random());
}

That would generate always the same "random" boolean since it's seeded with the same time. Instead you should reuse the random instance, fe in this way:

var rnd = new Random();
for(int i = 0; i < 1000; i++)
{
    bool randomBool = GetRandomBoolean(rnd);
}
