Convert::ToUInt32 Method (Object^, IFormatProvider^)

.NET Framework (current version)

Other Versions

Converts the value of the specified object to a 32-bit unsigned integer, using the specified culture-specific formatting information.

This API is not CLS-compliant.

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

Syntax

C++

public:
[CLSCompliantAttribute(false)]
static unsigned int ToUInt32(
	Object^ value,
	IFormatProvider^ provider
)

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::UInt32

A 32-bit unsigned integer that is equivalent to value, or zero if value is null.

Exceptions

Exception	Condition
FormatException	value is not in an appropriate format.
InvalidCastException	value does not implement the IConvertible interface. -or- The conversion is not supported.
OverflowException	value represents a number that is less than UInt32::MinValue or greater than UInt32::MaxValue.

Remarks

The return value is the result of invoking the IConvertible::ToUInt32 method of the underlying type of value.

provider enables the user to specify culture-specific conversion information about the contents of value. For example, if value is a String that represents a number, provider could supply culture-specific information about the notation used to represent that number.

The base types ignore provider; however, the parameter may be used if value is a user-defined type that implements the IConvertible interface.

Examples

The following example defines a HexString class that implements the IConvertible interface and that is designed to hold the string representation of both 32-bit signed and 32-bit unsigned values. The class includes a Sign property that indicates the sign of its hexadecimal value.

C++

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

The following example shows that a call to the ToUInt32(Object^, IFormatProvider^) method that passes a HexString object as a parameter, in turn, calls the IConvertible::ToUInt32 implementation of the HexString class.
