Answer 1

string[] str={"1","2","3"};
string[] str1={"1","2","3","4"};
string[] str2={"1","2","3","4","5"}; int count=0; for (int i=0;i<str.Length;i++)
{
for(int k=0;k<str1.Length;k++)
{
for (int j=0;j<str2.Length;j++)
{
Response.Write(str[i]+" "+str1[k]+" "+str2[j]+"<br>"); count++;
}
}

} Response.Write("共"+count+"条记录");
