当我从另一个类调用dnanumber变量时，在控制台中似乎是0。我该如何解决这个问题？
class DNAgenerator
{
public int dnanumber;
public int dna;
public int dna2;
public int dna3;
public int dna4;
public void generetor()
{
Random user = new Random();
dna = user.Next(1,41);
dna2 = user.Next(1,41);
dna3 = user.Next(1, 41);
dna4 = user.Next(1, 41);
Random nukleodite = new Random();
if (dna == nukleodite.Next(1,11))
{
dnanumber = 65;
}
else if(dna== nukleodite.Next(11, 21))
{
dnanumber = 67;
}
else if (dna == nukleodite.Next(21, 31))
{
dnanumber = 71;
}
else if(dna == nukleodite.Next(31,41))
{
dnanumber = 84;
}
// dna2
if (dna2 == nukleodite.Next(1, 11))
{
dnanumber = 65;
}
else if (dna2 == nukleodite.Next(11, 21))
{
dnanumber = 67;
}
else if (dna2 == nukleodite.Next(21, 31))
{
dnanumber = 71;
}
else if (dna2 == nukleodite.Next(31, 41))
{
dnanumber = 84;
}
//dna3
if (dna3 == nukleodite.Next(1, 11))
{
}
else if (dna3 == nukleodite.Next(11, 21))
{
}
else if (dna3 == nukleodite.Next(21, 31))
{
}
else if (dna3 == nukleodite.Next(31, 41))
{
}
//dna4
if (dna4 == nukleodite.Next(1, 11))
{
}
else if (dna4 == nukleodite.Next(11, 21))
{
}
else if (dna4 == nukleodite.Next(21, 31))
{
}
else if (dna4 == nukleodite.Next(31, 41))
{
}
}
}
