IsInstanceOfType(Object, Type, String)

Source:

Assert.IsInstanceOfType.cs

Tests whether the specified object is an instance of the expected type and throws an exception if the expected type is not in the inheritance hierarchy of the object.

public static void IsInstanceOfType (object? value, Type? expectedType, string? message);

static member IsInstanceOfType : obj * Type * string -> unit

Public Shared Sub IsInstanceOfType (value As Object, expectedType As Type, message As String)

Parameters

value
