Convert::ToByte Method (Object)

Converts the value of the specified object to an 8-bit unsigned integer.

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

public:
static unsigned char ToByte(
	Object^ value
)

Parameters

value
Type: System::Object
An object that implements the IConvertible interface, or nullptr.

Return Value

Type: System::Byte
An 8-bit unsigned integer that is equivalent to value, or zero if value is nullptr.

ExceptionCondition
FormatException

value is not in the property format for a Byte value.

InvalidCastException

value does not implement IConvertible.

-or-

Conversion from value to the Byte type is not supported.

OverflowException

value represents a number that is less than Byte::MinValue or greater than Byte::MaxValue.

If value is not nullptr, this method wraps a call to the IConvertible::ToByte implementation of the underlying type of value.

The following example uses the ToByte(Object) method to convert an array of objects to Byte values.

No code example is currently available or this language may not be supported.
