如何将值插入列表集合

Question

I need to insert elements into my empty list collection as one array item that contains Card and Date.

TimeOut Justification is my entity class that contains parameters like Card and Date

I'm checking if TimeOutArray is 0, then i need to insert Card and Date.

List<TimeOutJustification>TimeOutArray;

Result should look like this

[0] = {Card="1234",Date="12-03-19"};

Answer 1

It's not super clear to me what the scenario is here, but I am going to assume that the list TimeOutArray may or may not have been initialized, and may or may not have items. It sounds like you want to check for those things, and, if it does not have items, add one.

First, initialize the list if it is null:

if (TimeOutArray == null)
{
    TimeOutArray = new List<TimeOutJustification>();
}

Then, check if the item count is 0, and add the new item.

if (TimeOutArray.Count == 0)
{
    TimeOutArray.Add(new TimeOutJustification
    {
        Card = "1234",
        Date = "12-03-19"
    });
}
