Name Description
IsExactInstanceOfType(Object, Type, String, String)

Tests whether the specified object is exactly an instance of the expected type and throws an exception if the expected type does not match exactly.
IsExactInstanceOfType(Object, Type, Assert+AssertIsExactInstanceOfTypeInterpolatedStringHandler, String)

Tests whether the specified object is exactly an instance of the expected type and throws an exception if the expected type does not match exactly.
IsExactInstanceOfType<T>(Object, Assert.AssertGenericIsExactInstanceOfTypeInterpolatedStringHandler<T>, String)

Tests whether the specified object is exactly an instance of the generic type and throws an exception if the generic type does not match exactly.
IsExactInstanceOfType<T>(Object, String, String)

Tests whether the specified object is exactly an instance of the generic type and throws an exception if the generic type does not match exactly.

IsExactInstanceOfType(Object, Type, String, String)

Source:
Assert.IsExactInstanceOfType.cs

Tests whether the specified object is exactly an instance of the expected type and throws an exception if the expected type does not match exactly.

public static void IsExactInstanceOfType(object? value, Type? expectedType, string? message = "", string valueExpression = "");
static member IsExactInstanceOfType : obj * Type * string * string -> unit
Public Shared Sub IsExactInstanceOfType (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 exact type of value.

message
String

The message to include in the exception when value is not exactly 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 exactly the type of value.

Applies to

IsExactInstanceOfType(Object, Type, Assert+AssertIsExactInstanceOfTypeInterpolatedStringHandler, String)

Source:
Assert.IsExactInstanceOfType.cs

Tests whether the specified object is exactly an instance of the expected type and throws an exception if the expected type does not match exactly.

public static void IsExactInstanceOfType(object? value, Type? expectedType, ref Microsoft.VisualStudio.TestTools.UnitTesting.Assert.AssertIsExactInstanceOfTypeInterpolatedStringHandler message, string valueExpression = "");
static member IsExactInstanceOfType : obj * Type * AssertIsExactInstanceOfTypeInterpolatedStringHandler * string -> unit
Public Shared Sub IsExactInstanceOfType (value As Object, expectedType As Type, ByRef message As Assert.AssertIsExactInstanceOfTypeInterpolatedStringHandler, Optional valueExpression As String = "")

Parameters

value
Object

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

expectedType
Type

The expected exact type of value.

message
Assert.AssertIsExactInstanceOfTypeInterpolatedStringHandler

The message to include in the exception when value is not exactly 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.

Applies to

IsExactInstanceOfType<T>(Object, Assert.AssertGenericIsExactInstanceOfTypeInterpolatedStringHandler<T>, String)

Source:
Assert.IsExactInstanceOfType.cs

Tests whether the specified object is exactly an instance of the generic type and throws an exception if the generic type does not match exactly.

public static T IsExactInstanceOfType<T>(object? value, ref Microsoft.VisualStudio.TestTools.UnitTesting.Assert.AssertGenericIsExactInstanceOfTypeInterpolatedStringHandler<T> message, string valueExpression = "");
static member IsExactInstanceOfType : obj * AssertGenericIsExactInstanceOfTypeInterpolatedStringHandler * string -> 'T
Public Shared Function IsExactInstanceOfType(Of T) (value As Object, ByRef message As Assert.AssertGenericIsExactInstanceOfTypeInterpolatedStringHandler(Of T), Optional valueExpression As String = "") As T

Type Parameters
