Question

I have a List<string> and some saved values taken from a gridview. What I need is to use a few if statements in order to check if one of these values in the list are empty.

A simple for loop going through all the rows in the gridview and taking values from the right column:

for (int i = 0; i < GridView2.Rows.Count; i++)
{
            string tasks = GridView2.Rows[i].Cells[3].Text;
            datesList.Add(tasks); 
 }

Here is a very simple example of code I’m using to check if 2 is in the list:

if (datesList.Contains("2"))
{
    Label1.Text = "It contains it";
}
else
{
    Label1.Text = "No matches";    
} 

So does the list saves all values from the gridview no matter that some are empty?

Correct me if I’m wrong somewhere but it’s really confusing now…

Answer 1

if(datesList.Any(date => !String.IsNullOrEmpty(date)))
{
   //save
}

To collect the set/filled fields:

var setDates = datesList.Select(date => !String.IsNullOrEmpty(date));
