Class Reflect

Namespace

NUnit.Framework.Internal

Assembly

nunit.framework.dll

Helper methods for inspecting a type by reflection.

Many of these methods take ICustomAttributeProvider as an argument to avoid duplication, even though certain attributes can only appear on specific types of members, like MethodInfo or Type.

In the case where a type is being examined for the presence of an attribute, interface or named member, the Reflect methods operate with the full name of the member being sought. This removes the necessity of the caller having a reference to the assembly that defines the item being sought and allows the NUnit core to inspect assemblies that reference an older version of the NUnit framework.

object

An instance of the Type

Construct(Type, object[])

Invoke a constructor on a Type with arguments

public static object Construct(Type type, object[] arguments)

GetMethodsWithAttribute(Type, Type, bool)

Examine a fixture type and return an array of methods having a particular attribute. The array is order with base methods first.

public static MethodInfo[] GetMethodsWithAttribute(Type fixtureType, Type attributeType, bool inherit)

Parameters

fixtureType Type

The type to examine

attributeType Type

The attribute Type to look for

inherit bool

Specifies whether to search the fixture type inheritance chain

Returns

MethodInfo[]

The array of methods found

HasMethodWithAttribute(Type, Type)

Examine a fixture type and return true if it has a method with a particular attribute.

public static bool HasMethodWithAttribute(Type fixtureType, Type attributeType)

Parameters

fixtureType Type

The type to examine

attributeType Type

The attribute Type to look for

Returns

bool

True if found, otherwise false

InvokeMethod(MethodInfo, object)

Invoke a parameterless method returning void on an object.

public static object InvokeMethod(MethodInfo method, object fixture)

Parameters

method MethodInfo

A MethodInfo for the method to be invoked

fixture object

The object on which to invoke the method

Returns

object

InvokeMethod(MethodInfo, object, params object[])

Invoke a method, converting any TargetInvocationException to an NUnitException.

public static object InvokeMethod(MethodInfo method, object fixture, params object[] args)

Parameters

method MethodInfo

A MethodInfo for the method to be invoked

fixture object

The object on which to invoke the method

args object[]

The argument list for the method

Returns

object

The return value from the invoked method
