how to change a random variable to double ?

Hello .
I am newbe in C# and working on Randon type .
a part of my code is :

Code:

---

Random r = new Random();
Double R;
for(int i=0;i<10;++i)
{
    r.NextDouble();
    R=r;

---

but I get an error in the "R=r;" line .
is it possible to change a random variable to double ?

thank you

I forgot to say the goal .
I have an array of double between 0-1 and want to do some operations on it depend on the generated random r , but I get error messages in those lines

Code:

---

for(int i=0;i<10;++i)
      {
        r.NextDouble();
        if(r<qk[0])              <---one error here
        {
                atemp[i]=a[i];
                btemp[i]=b[i];
        }
        else
        {
                int j=1;
                while((j<10)&&(qk[j+1]<Math.Round(r,6)))  <---- here too 
                      j++;
                                        .
                                        .
                                        .

it is why I want to change it to double

thank you

The NextDouble() function returns the double. Try:

Code:

---

R = r.NextDouble();

thank you .
