Convert::ToByte Method (String, IFormatProvider)
Converts the specified string representation of a number to an equivalent 8-bit unsigned integer, using specified culture-specific formatting information.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System::String
A string that contains the number to convert.
- 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 does not consist of an optional sign followed by a sequence of digits (0 through 9). |
| OverflowException | value represents a number that is less than Byte::MinValue or greater than Byte::MaxValue. |
provider is an IFormatProvider instance that obtains a NumberFormatInfo object. The NumberFormatInfo object provides culture-specific information about the format of value. If provider is nullptr, the NumberFormatInfo object for the current culture is used.
If you prefer not to handle an exception if the conversion fails, you can call the Byte::TryParse method instead. It returns a Boolean value that indicates whether the conversion succeeded or failed.
The following example creates a custom NumberFormatInfo object that defines the positive sign as "pos" and the negative sign as "neg", which it uses in calls to the ToByte(String, IFormatProvider) method. It then calls the ToByte(String, IFormatProvider) method repeatedly to convert each element in a string array to a Byte value.
