Public Shared Function ToInt64 ( 
	str As String,
	Optional numberStyle As NumberStyles = NumberStyles.Integer,
	Optional provider As IFormatProvider = Nothing
) As Nullable(Of Long)

F#

[<ExtensionAttribute>]

        str : string * 
        ?numberStyle : NumberStyles * 
        ?provider : IFormatProvider 
(* Defaults:
        let _numberStyle = defaultArg numberStyle NumberStyles.Integer
        let _provider = defaultArg provider null
*)
-> Nullable<int64> 

Parameters

 

str

Type: System.String
A string containing a number to convert. The string is interpreted using the style specified by numberStyle.

numberStyle (Optional)

Type: System.Globalization.NumberStyles
A bitwise combination of enumeration values that indicates the style elements that can be present in str. Default value is Integer.

provider (Optional)

Type: System.IFormatProvider
An object that supplies culture-specific formatting information about str.

Return Value

Type: Nullable(Int64)
When this method returns, contains the Int64 value equivalent of the number contained in str, if the conversion succeeded, or null if the conversion failed. The conversion fails if the str parameter is null or String.Empty, is not in a format compliant withstyle, or represents a number less than MinValue or greater than MaxValue.
