Convert::ToByte Method (Object, IFormatProvider)
Converts the value of the specified object to an 8-bit unsigned integer, using the specified culture-specific formatting information.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System::Object
An object that implements the IConvertible interface.
- provider
- Type: System::IFormatProvider
An object that supplies culture-specific formatting information.
Return Value
Type: System::ByteAn 8-bit unsigned integer that is equivalent to value, or zero if value is nullptr.
| Exception | Condition |
|---|---|
| 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. |
provider enables the user to specify culture-specific conversion information about the contents of value. The base types ignore provider; however, the parameter may be used if value is a user-defined type that implements the IConvertible interface.
The following example defines a ByteString class that implements the IConvertible interface. The class stores the string representation of a byte value along with a sign field, so that it is able to represent both signed and unsigned byte values.
The following example instantiates several ByteString objects and calls the ToByte(Object, IFormatProvider) method to convert them to byte values. It illustrates that the ToByte(Object, IFormatProvider) method wraps a call to the IConvertible::ToByte method of the object to be converted.
