[Home] Type Microsoft.FSharp.Core.option


The type of optional values. When used from other .NET languages the empty option is the 'null' value. Use the constructors [[Some]] and [[None]] to create values of this type. Use the values in the [[Option]] module to manipulate values of this type, or pattern match against the values directly. 'None' values will appear as the value 'null' to other .NET languages. Instance methods on this type will appear as static methods to other .NET languages due to the use of 'null' as a value representation. Note: an abbreviation for Option<'a>
