Methods

CanDeduceTypeArgsFromArgs(Type, object?[], ref Type[]?)

Determines whether this instance can deduce type args for a generic type from the supplied arguments.

public static bool CanDeduceTypeArgsFromArgs(Type type, object?[] arglist, ref Type[]? typeArgsOut)

Parameters

type Type

The type to be examined.

arglist object[]

The arglist.

typeArgsOut Type[]
