Convert.ToString Method (Byte, Int32)
Converts the value of an 8-bit unsigned integer to its equivalent string representation in a specified base.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Byte
The 8-bit unsigned integer to convert.
- toBase
- Type: System.Int32
The base of the return value, which must be 2, 8, 10, or 16.
| Exception | Condition |
|---|---|
| ArgumentException | toBase is not 2, 8, 10, or 16. |
If toBase does not equal 10, the string that is returned by the Convert.ToString(Byte, Int32) method represents value by its magnitude only. If the method is called to create a string that will later be converted back to a number, a corresponding method that assumes a magnitude-only numeric representation should be called to perform the conversion. Such methods include Convert.ToByte(String, Int32) or Byte.Parse(String, NumberStyles).
The following example converts each element in a byte array to its equivalent binary, hexadecimal, decimal, and hexadecimal string representations.
int[] bases = { 2, 8, 10, 16}; byte[] numbers = { Byte.MinValue, 12, 103, Byte.MaxValue}; foreach (int baseValue in bases) { Console.WriteLine("Base {0} conversion:", baseValue); foreach (byte number in numbers) { Console.WriteLine(" {0,-5} --> 0x{1}", number, Convert.ToString(number, baseValue)); } } // The example displays the following output: // Base 2 conversion: // 0 --> 0x0 // 12 --> 0x1100 // 103 --> 0x1100111 // 255 --> 0x11111111 // Base 8 conversion: // 0 --> 0x0 // 12 --> 0x14 // 103 --> 0x147 // 255 --> 0x377 // Base 10 conversion: // 0 --> 0x0 // 12 --> 0x12 // 103 --> 0x103 // 255 --> 0x255 // Base 16 conversion: // 0 --> 0x0 // 12 --> 0xc // 103 --> 0x67 // 255 --> 0xff
