This method is used to return a Boolean value converted from the byte at a specified position in a byte array.
Syntax:
public static bool ToBoolean (byte[] value, int startIndex);
Parameters:
value: It is the required byte array.
startIndex: It is the index of the byte within value.
Return Value: This method returns true if the byte at startIndex in value is nonzero otherwise it will return false.
Exceptions:
- ArgumentNullException: If the value is null.
- ArgumentOutOfRangeException: If the startIndex is less than zero or greater than the length of value minus 1.
Below programs illustrate the use of BitConverter.ToBoolean(Byte[], Int32) Method:
Example 1:
// C# program to demonstrate // BitConverter.ToBoolean(bytes, index)); // Method using System;
class GFG {
// Main Method
public static void Main()
{
try {
// Define an array of byte values.
byte [] bytes = { 0, 1, 2, 4, 8, 16, 32, 64 };
// Display the values of the myArr.
Console.Write( "Initial Array: " );
// calling the PrintIndexAndValues()
// method to print
PrintIndexAndValues(bytes);
for ( int index = 0; index < bytes.Length; index++) {
bool values = BitConverter.ToBoolean(bytes, index);
Console.WriteLine( "index element bool" );
Console.WriteLine( " {0} {1} {2}" ,
index, bytes[index], values);
}
}
catch (ArgumentNullException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
catch (ArgumentOutOfRangeException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
// Defining the method
// PrintIndexAndValues
public static void PrintIndexAndValues( byte [] myArr)
{
for ( int i = 0; i < myArr.Length; i++) {
Console.Write( "{0} " , myArr[i]);
}
Console.WriteLine();
Console.WriteLine();
}
} |
Output:
Initial Array: 0 1 2 4 8 16 32 64 index element bool 0 0 False index element bool 1 1 True index element bool 2 2 True index element bool 3 4 True index element bool 4 8 True index element bool 5 16 True index element bool 6 32 True index element bool 7 64 True
Example 2: For ArgumentOutOfRangeException
// C# program to demonstrate // BitConverter.ToBoolean(bytes, index)); // Method using System;
class GFG {
// Main Method
public static void Main()
{
try {
// Define an array of byte values.
byte [] bytes = { 0, 1, 2, 4, 8, 16, 32, 64 };
// Display the values of the myArr.
Console.Write( "Initial Array: " );
// calling the PrintIndexAndValues()
// method to print
PrintIndexAndValues(bytes);
Console.WriteLine( "startindex in less than zero" );
bool values = BitConverter.ToBoolean(bytes, -1);
}
catch (ArgumentNullException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
catch (ArgumentOutOfRangeException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
// Defining the method
// PrintIndexAndValues
public static void PrintIndexAndValues( byte [] myArr)
{
for ( int i = 0; i < myArr.Length; i++) {
Console.Write( "{0} " , myArr[i]);
}
Console.WriteLine();
Console.WriteLine();
}
} |
Output:
Initial Array: 0 1 2 4 8 16 32 64 startindex in less than zero Exception Thrown: System.ArgumentOutOfRangeException
Example 3: For ArgumentNullException
// C# program to demonstrate // BitConverter.ToBoolean(bytes, index)); // Method using System;
class GFG {
// Main Method
public static void Main()
{
try {
// Define an array of byte values.
byte [] bytes = null ;
// Getting bool value
Console.WriteLine( "byte array is null" );
bool values = BitConverter.ToBoolean(bytes, 0);
}
catch (ArgumentNullException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
catch (ArgumentOutOfRangeException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}

Output:
byte array is null Exception Thrown: System.ArgumentNullException
