Create<T>(Func<String, CultureInfo, (Boolean, T)>)

Creates an IValueParser<T> implementation given a parsing function that receives an argument name, a value to parse, a culture to use for parsing and returns a tuple whose first element indicates whether parsing was successful and second element is the parsed value.

Declaration
public static IValueParser<T> Create<T>(Func<string, CultureInfo, (bool, T)> parser)
Parameters
Type Name Description
System.Func<System.String, System.Globalization.CultureInfo, System.ValueTuple<System.Boolean, T>> parser
Returns
Type Description
IValueParser<T>

Create<T>(Func<String, CultureInfo, (Boolean, T)>, Func<String, String, FormatException>)

Creates an IValueParser<T> implementation given a parsing function that receives an argument name, a value to parse, a culture to use for parsing and returns a tuple whose first element indicates whether parsing was successful and second element is the parsed value. An additional parameter specifies a function that returns the System.FormatException to throw, given the argument name and value, when parsing is unsuccessful.

Declaration
public static IValueParser<T> Create<T>(Func<string, CultureInfo, (bool, T)> parser, Func<string, string, FormatException> errorSelector)
Parameters
Type Name Description
System.Func<System.String, System.Globalization.CultureInfo, System.ValueTuple<System.Boolean, T>> parser
System.Func<System.String, System.String, System.FormatException> errorSelector
Returns
Type Description
IValueParser<T>
