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

public:
static float ToSingle(
	String^ value,
	IFormatProvider^ provider
)

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::Single

A single-precision floating-point number that is equivalent to the number in value, or 0 (zero) if value is null.

Exception Condition
FormatException

value is not a number in a valid format.

OverflowException

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

The return value is the result of invoking the Single::Parse method on value.

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 null, the NumberFormatInfo for the current culture is used.

If you prefer not to handle an exception if the conversion fails, you can call the Single::TryParse method instead. It returns a Boolean value that indicates whether the conversion succeeded or failed.

The following example uses IFormatProvider objects that represent the en-US and fr-FR cultures when it converts the elements in an array of numeric strings to Single values.
