How to call function with List in head

Question

I want to send along several integers with my function through a list like this:

public string createCompleteJump(List<int>kID)

kID is they key ID which is connected to several dictionaries hence why it is important to select different integers.

function:

public string createCompleteJump(List<int>kID)
{
    // List<int> kID = new List<int>(); // Key ID
    double vID = 3; // Value ID
    string v2ID = "Framåt";
    var myKey = qtyScrews[kID[0]].FirstOrDefault(y => y == vID);
    var myKey2 = qtyFlips[kID[1]];
    var myKey3 = jumpCombination[kID[2]].FirstOrDefault(y => y == v2ID);
    var myKey4 = jumpHeight[kID[3]];
    var myKey5 = startPos[kID[4]];

    var str = $"{myKey}{myKey2}{myKey3}{myKey4}{myKey5}";
    Console.Write("\nCompleteJump:" + str);
    return str;
}

How would I send along 5 arguments when calling the function through a list? Eg:

public string createCompleteJump(3,4,2,3,4)

Answer 1

You either need to create a list to pass as argument:

createCompleteJump(new List<int> {3,4,2,3,4});

or you could change your method to accept an undefined number of arguments:

public string createCompleteJump(params int[] kID)
{ /* ... */ }

The params key word states that there can be an arbitrary number of int and that they are combined into an array:

createCompleteJump(3,4,2,3,4);

results in an int[] array containing the specified values.

Answer 2

use params keyword:

public string createCompleteJump(params int[] kID)

Answer 3

You can use params or you can instantiate your list to be sent to your function, like this:

List<int> keyIDList = new List<int> {3,4,2,3,4};
createCompleteJump(keyIDList)
