_AppDomain.CreateInstanceFrom Method

Definition

Provides COM objects with version-independent access to the CreateInstanceFrom method.

Overloads

CreateInstanceFrom(String, String)

Provides COM objects with version-independent access to the CreateInstanceFrom(String, String) method overload.

CreateInstanceFrom(String, String, Object[])

Provides COM objects with version-independent access to the CreateInstanceFrom(String, String, Object[]) method overload.

CreateInstanceFrom(String, String, Boolean, BindingFlags, Binder, Object[], CultureInfo, Object[], Evidence)

Provides COM objects with version-independent access to the CreateInstanceFrom(String, String, Boolean, BindingFlags, Binder, Object[], CultureInfo, Object[], Evidence) method overload.

CreateInstanceFrom(String, String)

Provides COM objects with version-independent access to the CreateInstanceFrom(String, String) method overload.

public:
 System::Runtime::Remoting::ObjectHandle ^ CreateInstanceFrom(System::String ^ assemblyFile, System::String ^ typeName);
public System.Runtime.Remoting.ObjectHandle CreateInstanceFrom (string assemblyFile, string typeName);
abstract member CreateInstanceFrom : string * string -> System.Runtime.Remoting.ObjectHandle
Public Function CreateInstanceFrom (assemblyFile As String, typeName As String) As ObjectHandle

Parameters

assemblyFile
String

The name, including the path, of a file that contains an assembly that defines the requested type. The assembly is loaded using the LoadFrom(String) method.

typeName
String

The fully qualified name of the requested type, including the namespace but not the assembly, as returned by the FullName property.

Returns

An object that is a wrapper for the new instance, or null if typeName is not found. The return value needs to be unwrapped to access the real object.

Remarks

See the AppDomain.CreateInstanceFrom(String, String) method overload.

Applies to

CreateInstanceFrom(String, String, Object[])

Provides COM objects with version-independent access to the CreateInstanceFrom(String, String, Object[]) method overload.

public:
 System::Runtime::Remoting::ObjectHandle ^ CreateInstanceFrom(System::String ^ assemblyFile, System::String ^ typeName, cli::array <System::Object ^> ^ activationAttributes);
public System.Runtime.Remoting.ObjectHandle CreateInstanceFrom (string assemblyFile, string typeName, object[] activationAttributes);
abstract member CreateInstanceFrom : string * string * obj[] -> System.Runtime.Remoting.ObjectHandle
Public Function CreateInstanceFrom (assemblyFile As String, typeName As String, activationAttributes As Object()) As ObjectHandle

Parameters

assemblyFile
String

The name, including the path, of a file that contains an assembly that defines the requested type. The assembly is loaded using the LoadFrom(String) method.

typeName
String

The fully qualified name of the requested type, including the namespace but not the assembly, as returned by the FullName property.

activationAttributes
Object[]

An array of one or more attributes that can participate in activation. Typically, an array that contains a single UrlAttribute object. The UrlAttribute specifies the URL that is required to activate a remote object.

Returns

An object that is a wrapper for the new instance, or null if typeName is not found. The return value needs to be unwrapped to access the real object.

Remarks

See the AppDomain.CreateInstanceFrom(String, String, Object[]) method overload.

The activationAttributes parameter is related to client-activated objects, a legacy technology.

Applies to

CreateInstanceFrom(String, String, Boolean, BindingFlags, Binder, Object[], CultureInfo, Object[], Evidence)

Provides COM objects with version-independent access to the CreateInstanceFrom(String, String, Boolean, BindingFlags, Binder, Object[], CultureInfo, Object[], Evidence) method overload.

public:
 System::Runtime::Remoting::ObjectHandle ^ CreateInstanceFrom(System::String ^ assemblyFile, System::String ^ typeName, bool ignoreCase, System::Reflection::BindingFlags bindingAttr, System::Reflection::Binder ^ binder, cli::array <System::Object ^> ^ args, System::Globalization::CultureInfo ^ culture, cli::array <System::Object ^> ^ activationAttributes, System::Security::Policy::Evidence ^ securityAttributes);
public System.Runtime.Remoting.ObjectHandle CreateInstanceFrom (string assemblyFile, string typeName, bool ignoreCase, System.Reflection.BindingFlags bindingAttr, System.Reflection.Binder binder, object[] args, System.Globalization.CultureInfo culture, object[] activationAttributes, System.Security.Policy.Evidence securityAttributes);
abstract member CreateInstanceFrom : string * string * bool * System.Reflection.BindingFlags * System.Reflection.Binder * obj[] * System.Globalization.CultureInfo * obj[] * System.Security.Policy.Evidence -> System.Runtime.Remoting.ObjectHandle
Public Function CreateInstanceFrom (assemblyFile As String, typeName As String, ignoreCase As Boolean, bindingAttr As BindingFlags, binder As Binder, args As Object(), culture As CultureInfo, activationAttributes As Object(), securityAttributes As Evidence) As ObjectHandle

Parameters

assemblyFile
String

The name, including the path, of a file that contains an assembly that defines the requested type. The assembly is loaded using the LoadFrom(String) method.

typeName
String

The fully qualified name of the requested type, including the namespace but not the assembly, as returned by the FullName property.

ignoreCase
Boolean

A Boolean value specifying whether to perform a case-sensitive search or not.

bindingAttr
BindingFlags

A combination of zero or more bit flags that affect the search for the typeName constructor. If bindingAttr is zero, a case-sensitive search for public constructors is conducted.

binder
Binder

An object that enables the binding, coercion of argument types, invocation of members, and retrieval of MemberInfo objects through reflection. If binder is null, the default binder is used.

args
Object[]

The arguments to pass to the constructor. This array of arguments must match in number, order, and type the parameters of the constructor to invoke. If the parameterless constructor is preferred, args must be an empty array or null.

culture
CultureInfo

Culture-specific information that governs the coercion of args to the formal types declared for the typeName constructor. If culture is null, the CultureInfo for the current thread is used.

activationAttributes
Object[]

An array of one or more attributes that can participate in activation. Typically, an array that contains a single UrlAttribute object. The UrlAttribute specifies the URL that is required to activate a remote object.

securityAttributes
Evidence

Information used to authorize creation of typeName.

Returns

An object that is a wrapper for the new instance, or null if typeName is not found. The return value needs to be unwrapped to access the real object.

Remarks

See the AppDomain.CreateInstanceFrom(String, String, Boolean, BindingFlags, Binder, Object[], CultureInfo, Object[], Evidence) method overload.

The activationAttributes parameter is related to client-activated objects, a legacy technology.
