Remarks

This overload of the Parse(String, IFormatProvider) method is typically used to convert text that can be formatted in a variety of ways to a UInt32 value. For example, it can be used to convert the text entered by a user into a text box to a numeric value.

The s parameter contains a number of the form:

[ws][sign]digits[ws]

Items in square brackets ([ and ]) are optional. The following table describes each element.

The s parameter is interpreted using the NumberStyles.Integer style. In addition to the unsigned integer value's decimal digits, only leading and trailing spaces along with a leading sign is allowed. (If the negative sign is present, s must represent a value of zero, or the method throws an OverflowException.) To explicitly define the style elements together with the culture-specific formatting information that can be present in s, use the Parse(String, NumberStyles, IFormatProvider) method.

The provider parameter is an IFormatProvider implementation whose GetFormat method returns a NumberFormatInfo object that provides culture-specific information about the format of s. There are three ways to use the provider parameter to supply custom formatting information to the parse operation:

• You can pass the actual NumberFormatInfo object that provides formatting information. (Its implementation of GetFormat simply returns itself.)

• You can pass a CultureInfo object that specifies the culture whose formatting is to be used. Its NumberFormat property provides formatting information.

• You can pass a custom IFormatProvider implementation. Its GetFormat method must instantiate and return the NumberFormatInfo object that provides formatting information.

If provider is nulla null reference (Nothing in Visual Basic), the NumberFormatInfo for the current culture is used.
