Returns a Boolean value converted from the byte at a specified position in a byte array.

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

Public Shared Function ToBoolean (
	value As Byte(),
	startIndex As Integer
) As Boolean

Parameters

value
Type: System.Byte()

A byte array.

startIndex
Type: System.Int32

The index of the byte within value.

Return Value

Type: System.Boolean

true if the byte at startIndex in value is nonzero; otherwise, false.

Exception Condition
ArgumentNullException

value is null.

ArgumentOutOfRangeException

startIndex is less than zero or greater than the length of value minus 1.

To convert a Boolean value to its byte representation, call the ToBoolean method.

The following code example converts elements of Byte arrays to Boolean values with the ToBoolean method.

Module Example
    Public Sub Main()
        ' Define an array of byte values. 
        Dim bytes() As Byte = { 0, 1, 2, 4, 8, 16, 32, 64, 128, 255 }

        Console.WriteLine("{0,5}{1,16}{2,10}\n", "index", "array element", "bool" )
        ' Convert each array element to a Boolean value.
        For index As Integer = 0 To bytes.Length - 1
           Console.WriteLine("{0,5}{1,16:X2}{2,10}", index, bytes(index), 
                             BitConverter.ToBoolean(bytes, index))
        Next                     
    End Sub 
End Module
' The example displays the following output:
'     index   array element      bool
'     
'         0              00     False
'         1              01      True
'         2              02      True
'         3              04      True
'         4              08      True
'         5              10      True
'         6              20      True
'         7              40      True
'         8              80      True
'         9              FF      True
