Is there any way to do this, assign a value within a List.ForEach() statement?

Question

I have this:

var lineArray = line.Split(\';\');

lineArray.ToList().ForEach(x =>
{
    if (x == \"(null)\")
        x = \"NULL\";
    else
        x = string.         


        

Answer 1

don't use ForEach like that - use a for loop.

for (int i = 0; i < lineArray.Length; i++)
{
    if (lineArray[i] == "(null)")
        lineArray[i] = "NULL";
    else
        lineArray[i] = string.Format("'{0}'", lineArray[i]);
}
