How to check List for value in a specific range of values in .NET

Say I have a list with random values

11, 22, 33, 44, 55, 66, 77, 88

I want to extract all values between 20-60 lets say which uses the value lets say 40 with offsets -20 and +20.

so I should get 22,33,44,55 only

Code

uint Val = 40;
List<uint> List1 = new List<uint>() {11, 22, 33, 44, 55, 66, 77, 88};
List<uint> CheckedList = List1.Where(t => (Val - 20) >= t && t <= (Val + 20));

I tried this code and I cannot get it to compile Linq is very difficult to grasp.

 List<uint> CheckedList = List1.Where(t => t>= (Val - 20)  && t <= (Val + 20)).ToList();

Result: 22,33,44 and 55.

Append ToList if you want a list:

List<uint> CheckedList = List1.Where(t => t >= (Val - 20) && t <= (Val + 20)).ToList();

LINQ methods mostly return IEnumerable<T>, to get a List you can either use ToList method:

 List<uint> CheckedList = List1.Where(t => (Val - 20) >= t && t <= (Val + 20))
                               .ToList();

or call a List constructor that takes IEnumerable<T> :

 List<uint> CheckedList = new List<uint>(list1.Where(t => (Val - 20) >= t && t <= (Val + 20)));

You can Try this

List<uint> rangeList=new List<uint>();
foreach(var values in List1)
{
  if(values>=(val-20) && values<=(val+20))
  {
       rangeList.Add(values);
  }
}
