Random Name Picker
I have a class which contains 10 names (U1, U2, U3..and so on). I have to choose 5 names everyday, and display one as the Editor and 4 as Contributors
While selecting the random names, I have to also consider that if one user is selected as Editor, he cannot become editor again till everyone got their chance.
The output should look similar to the following:
Editor Cont1 Cont2 Cont3 Cont4
20-Jun U1 U8 U9 U3 U4
21-Jun U7 开发者_运维知识库 U2 U5 U6 U10
22-Jun U3 U4 U9 U2 U8
23-Jun U4 U8 U3 U5 U2
and so on..
Can I do this in LINQ?
I would not use Linq, but instead use the Random class provided by the .Net Framework.
Random random = new Random();
List<Person> tmpList = new List<Person>(personList);
int item = random.Next(tmpList.Count);
Person editor = tmpList[item];
tmpList.RemoveAt(item);
List<Person> contributors = new List<Person>();
for(int i = 0; i < 5; i++)
{
item = random.Next(tmpList.Count);
contributors.Add(tmpList[item]);
tmpList.RemoveAt(item);
}
