Question

I need to insert a value into an array… ideally I could just start with List<myObj>, but the methods I need to use return myObj[] instead.

I always need to insert a value into the first position, and rather than worm the values already in the array… I came up with the following scheme..

    List<myObj> list = array.ToList<myObj>();
        if (list.Count > 0 && list != null)
        {
            list.Insert(0, InsertRecord(myParam)); // InsertRecord() is one of my methods...
        }
        return list.ToArray();

My question is… is this even remotely efficient? Is there a better way to go about doing what I need to accomplish?

I think you can save some time with

var newArray = new myObj[oldArray.Length  + 1];    
oldArray.CopyTo(newArray, 1);
newArray[0] = InsertRecord(myParam);
