I want to thank in advance anyone who's able to help me here. Hi my question is relating to my code for my list and Case . The method that i've used RemoveRange only removes the numbers that i have added to my list at certain indexes. Do i need to use a different method or how do i remove it at randomly without removing it at certain indexes. meaning currently if i curently generate a random index and a random number to remove. current if i generate a random index of 2 and random number to remove of 3. it will remove index 3, 4, 5. how do i randomly say. randomly remove at any position. For exampl.. i have numbers 1,2,3,4,5,6. i have a random count of 3 i want to randomly remove 1, 4, 6 instead of removing at certain index. The next question deals with my case statement. currently i have my switch statement related to the count on my list. If the count is equal to 2 i send it to one of my case statement. What i want to do is have the count related to multiple Case statements. Meaning if I return a count of 2 have my application randomly choose one the multiple case statement that i have set for that count. I don't know how to set this case statment properly or if i should be using some other statement such as if or if my doing my switch statemtent all wrong.. ..

Here is my code for my question..

List<int> firstlist = new List<int>();
Random listRand = new Random();

// Predicate<int> mypred = new Predicate<int>();

//We add these number from the textbox to a list
firstlist.Add(numTxt1);
firstlist.Add(numTxt2);
firstlist.Add(numTxt3);
firstlist.Add(numTxt4);
firstlist.Add(numTxt5);
firstlist.Add(numTxt6);

int size = listRand.Next(0,2);
int item = listRand.Next(3,5);
firstlist.RemoveRange(size,item);
//int size = firstlist.Count;
//while (size > 0)
//{

// size--;
// int index = (new Random()).Next(0, size);
// int elem = firstlist[index];
// firstlist[index] = firstlist[size];

// MessageBox.Show(elem.ToString());


//}
//listRand.Next(1, 3);

//(4 & (1 + mynumb.Next())) - 1
int listint01 = 1,
listint02 = 2,
listint03 = 3;
listint01 = firstlist.Count;
listint02 = firstlist.Count;
listint03 = firstlist.Count;


switch (firstlist.Count)
{
case 1:
firstlist[0] = firstlist[0] + 1;
break;

//case 1:
// firstlist[0] = firstlist[0] - 1;
// break;

//case 1:
// firstlist[0] = firstlist[0];
// break;

case 2:
// Add one
firstlist[0] = firstlist[0] + 1;
firstlist[1] = firstlist[1] - 1;
break;

//case 2:
// // Add one
// firstlist[0] = firstlist[0] - 1;
// firstlist[1] = firstlist[1] + 1;
// break;

//case 2:
// // Add one
// firstlist[0] = firstlist[0] - 1;
// firstlist[1] = firstlist[1];
// break;

//case 2:
// // Add one
// firstlist[0] = firstlist[0] + 1;
// firstlist[1] = firstlist[1];
// break;

case 3:
// Add one
firstlist[0] = firstlist[0] + 1;
firstlist[1] = firstlist[1] - 1;
firstlist[2] = firstlist[2];
break;

//case 3:
// // Subtract one
// firstlist[0] = firstlist[0] - 1;
// firstlist[1] = firstlist[1] + 1;
// firstlist[2] = firstlist[2];
// break;

//case 3:
// // Leave as is
// firstlist[0] = firstlist[0];
// firstlist[1] = firstlist[1];
// firstlist[2] = firstlist[2] - 1;

// break;
//case 3:
// firstlist[0] = firstlist[0];
// firstlist[1] = firstlist[1];
// firstlist[2] = firstlist[2] + 1;
// break;
