Convert.ToByte Method (Int32)

Converts the value of the specified 32-bit signed integer to an equivalent 8-bit unsigned integer.

Namespace:  System
Assemblies:   System.Runtime.Extensions (in System.Runtime.Extensions.dll)
  mscorlib (in mscorlib.dll)

'Declaration
Public Shared Function ToByte ( _
	value As Integer _
) As Byte

Parameters

value
Type: System.Int32

The 32-bit signed integer to convert.

Return Value

Type: System.Byte
An 8-bit unsigned integer that is equivalent to value.

ExceptionCondition
OverflowException

value is less than Byte.MinValue or greater than Byte.MaxValue.

The following example converts an array of Int32 values to Byte values.

Dim numbers() As Integer = { Int32.MinValue, -1, 0, 121, 340, Int32.MaxValue }
Dim result As Byte 
For Each number As Integer In numbers
   Try
      result = Convert.ToByte(number)
      Console.WriteLIne("Converted the {0} value {1} to the {2} value {3}.", _
                        number.GetType().Name, number, _
                        result.GetType().Name, result)
   Catch e As OverflowException
      Console.WriteLine("The {0} value {1} is outside the range of the Byte type.", _
                        number.GetType().Name, number)
   End Try 
Next 
' The example displays the following output: 
'       The Int32 value -2147483648 is outside the range of the Byte type. 
'       The Int32 value -1 is outside the range of the Byte type. 
'       Converted the Int32 value 0 to the Byte value 0. 
'       Converted the Int32 value 121 to the Byte value 121. 
'       The Int32 value 340 is outside the range of the Byte type. 
'       The Int32 value 2147483647 is outside the range of the Byte type.
