Question

I have two lists and I want to copy data from one to another and I get this error:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Here’s my code:

static  IList<Common.Data.Driver> Stt_driverList = new List<Common.Data.Driver>();
List<Common.Data.Driver> driverList = new List<Common.Data.Driver>();

for (int i = 0; i < driverList.Count; i++)
{
    //Fill in The Static Driver List
    Stt_driverList[i] = driverList[i]; 
}

Answer 1

Stt_driverList does not contain any items when you start looping, so you can’t refer to elements by index. Try using the Add method instead:

static IList Stt_driverList = new List();
IList driverList = new List();
for (int i = 0; i < driverList.Count; i++)
{
    //Fill in The Static Driver List
    Stt_driverList.Add(driverList[i]);
}
