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.
