Number system conversion using C#.NET Decimal to Hexadecimal Input: Range Min:0, Max:18446744073709551615 or (2^64 - 1). Datatype UInt64 Processing input.ToString(“X”); Output: Datatype string Range Min:0h, Max:FFFFFFFFFFFFFFFFh.

Hexadecimal to Decimal Input: Range Min:0h, Max:FFFFFFFFFFFFFFFFh. Datatype string Processing UInt64.Parse(input, System.Globalization.NumberStyles.HexNumber).ToString(); Output: Range Min:0, Max:18446744073709551615 or (2^64 - 1). Datatype string

Decimal to Binary Input: Range Min:0, Max:18446744073709551615 or (2^64 - 1). Datatype UInt64 Processing ... string binaryStr = String.Empty; while (input > 0) { binaryStr += (input % 2).ToString(); input /= 2; } // Arrange the humanreadable format MSB on leftmost end and LSB on righmost end. binaryStr = ReverseString(binaryStr); return binaryStr; ... private static string ReverseString(string str) { char[] charArray = str.ToCharArray(); Array.Reverse(charArray); return new string(charArray); } Output: Range 0 – 64 bit Datatype string

Binary to Decimal Input: Range 0 to 64 bit Datatype string Processing Convert.ToUInt64(input, 2).ToString(); Output: Range Min:0, Max:18446744073709551615 or (2^64 - 1). Datatype string
