Convert.ToByte Method (Int64)

 

Converts the value of the specified 64-bit signed integer to an equivalent 8-bit unsigned integer.

Namespace:   System
Assembly:  mscorlib (in mscorlib.dll)

Public Shared Function ToByte (
	value As Long
) As Byte

Parameters

value
Type: System.Int64

The 64-bit signed integer to convert.

Return Value

Type: System.Byte

An 8-bit unsigned integer that is equivalent to value.

Exception Condition
OverflowException

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

The following example converts an array of Int64 values to Byte values.

Dim numbers() As Long = { Int64.MinValue, -1, 0, 121, 340, Int64.MaxValue }
Dim result As Byte
For Each number As Long 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 Int64 value -9223372036854775808 is outside the range of the Byte type.
'       The Int64 value -1 is outside the range of the Byte type.
'       Converted the Int64 value 0 to the Byte value 0.
'       Converted the Int64 value 121 to the Byte value 121.
'       The Int64 value 340 is outside the range of the Byte type.
'       The Int64 value 9223372036854775807 is outside the range of the Byte type.
