IsInstanceOfType(Object, Type, String, 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 = "", string valueExpression = "");

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

Public Shared Sub IsInstanceOfType (value As Object, expectedType As Type, Optional message As String = "", Optional valueExpression As String = "")

Parameters

value: Object

The object the test expects to be of the specified type.

expectedType: Type

The expected type of value.

message: String

The message to include in the exception when value is not an instance of expectedType. The message is shown in test results.

valueExpression: String

The syntactic expression of value as given by the compiler via caller argument expression. Users shouldn't pass a value for this parameter.

Exceptions

AssertFailedException

Thrown if value is null or expectedType is not in the inheritance hierarchy of value.
