I have list with empty space("__")
List<string> MyList = (List<string>)Session["MyList "];
if(MyList !=null || MyList != "")
{
}
MyList != "" does not work if string has more space so
How can i check my list string is "" or null by using linq in c# ?
if(MyList!=null || MyList.All(x=>string.IsNullOrWhiteSpace(x)))
{
}
Try this:
if(MyList.All(s=>string.IsNullOrWhiteSpace(s)))
{
....
}
var emptyStrings = MyList.Where(p => string.IsNullOrWhiteSpace(p)).ToList();
var listWithoutEmptyStrings = MyList.Where(p => string.IsNullOrWhiteSpace(p)).ToList();
If you just want to check if the list contains one ore more such items:
if (MyList.Any(p => string.IsNullOrWhiteSpace(p)))
{
}
If you want to check if all elements are null or empty
if (MyList.All(p => string.IsNullOrWhiteSpace(p)))
{
}
"". What is it you want to check exactly?Session["MyList "]might be just that, guess that's what the OP means.
