Field

Extension method: TResult? NullOr<TInput, TResult>(this TInput, FuncClass<TInput, TResult?>)

Declared in: RT.Util.Ut

Declaration

public static TResult? NullOr<TInput, TResult>(
    this TInput input,
    FuncClass<TInput, TResult?> lambda
)

Summary

Returns null if the input is null, otherwise the result of the specified lambda when applied to the input.

Generic type parameters

TInput Must be a reference type.	Type of the input value.
TResult Must derive from: System.ValueType. Must have a default constructor. Must be a non-nullable value type.	Type of the result from the lambda.

Parameters

this TInput	input	Input value to check for null.
FuncClass<TInput, TResult?>	lambda	Function to apply the input value to if it is not null.
