This method is used to return a Boolean value converted from the byte at a specified position in a byte array.
Syntax:
CSHARP

Output:
CSHARP
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.
