The second example would be plain wrong. Don't you mean
70.05 -> 70.1 or
70.5 -> 71 instead?

Be clear. You said "<0.5 set round off or > 0.5 add +1 in my decimal values", what happens to "0.5"?

Be clear of what you want. Be clear. You said "<0.5 set round off or > 0.5 add +1 in my decimal values", what happens to "0.5"? Let's follow this Rounding Numbers[^]
In c#, you can use Math.Round with MidpointRounding.AwayFromZero option[^] to achieve your desired rounding result.
But before that, you have to check the validity of the decimal number from the text box by using Decimal.TryParse Method (String, Decimal) (System)[^]. Putting things together, it looks like this:

C#

using System;

public class Program
{
	public static void Main()
	{
		string value;
		decimal number;
		value = "70.13";
		if (Decimal.TryParse(value, out number))
	
   			Console.WriteLine(Math.Round(number,1,MidpointRounding.AwayFromZero));
		else
   			Console.WriteLine("Unable to parse '{0}'.", value);
	}
}

Solution 1

C#

static void Main(string[] args)
      {
          decimal val1 = 10.51M;
          decimal val2 = 10.49M;

           val1 = Math.Round(val1,1);
           val2 = Math.Round(val2,1);
           Console.WriteLine(val1);
           Console.WriteLine(val2);
          Console.ReadLine();
      }
