To get the assembly that contains the method that called the currently executing code, use GetCallingAssembly.

NET framework can create an instance of a given type using early binding or late binding.

In early binding, we typically set the external assembly reference in the project and allocate the type using the new operator. Early binding allows us to determine errors at compile time rather than at runtime.

Whereas in late binding, you can create an instance of a given type and invoke its methods at runtime without having knowledge at compile time.

There is no provision to set an external assembly reference in this construct. We can create a late binding instance of an external assembly using the CreateInstance method of the System. Activator static class. Here, we are dynamically instantiating a utility class of the TestLib. GetType "TestLib. CreateInstance t ; Console. GetMethod "Test" ; mth. Invoke obj, null ; Console.

Once the code is complete and you compile this application, you obtain this output as:. View All. Using Reflection with C. Vidya Vrat Agarwal Updated date Feb 26, Assemblies are the core unit of deployment. This namespace contains numerous related types as follows:.

The following program depicts the process of reflection by creating a console based application. Technically, the act of loading external assemblies on demand is known as Dynamic Loading. To load assemblies dynamically, the Assembly class provides the following static methods Shared methods in Visual Basic. Assemblies are loaded into the application domain where the load operation occurs.

The recommended way to load assemblies is to use the Load method, which identifies the assembly to be loaded by its display name for example, "System. The search for the assembly follows the rules described in How the Runtime Locates Assemblies. For example, an assembly that targets a bit platform can be examined by code that is running on a bit platform. The LoadFile and LoadFrom methods are provided for rare scenarios in which an assembly must be identified by path.

To get an Assembly object for the currently executing assembly, use the GetExecutingAssembly method. Many members of the Assembly class provide information about an assembly. For example:. The GetName method returns an AssemblyName object that provides access to the parts of the assembly display name. The GetCustomAttributes method lists the attributes applied to the assembly. The GetFiles method provides access to the files in the assembly manifest.

The GetManifestResourceNames method provides the names of the resources in the assembly manifest. The GetTypes method lists all the types in the assembly. The GetExportedTypes method lists the types that are visible to callers outside the assembly.

The GetType method can be used to search for a particular type in the assembly. The CreateInstance method can be used to search for and create instances of types in the assembly.

For more information on assemblies, see the "Application Domains and Assemblies" section in the Application Domains topic. Initializes a new instance of the Assembly class. Gets the location of the assembly as specified originally, for example, in an AssemblyName object.

Gets a collection of the public types defined in this assembly that are visible outside the assembly. Gets a value indicating whether the assembly was loaded from the global assembly cache. NET Framework only. Gets a string representing the version of the common language runtime CLR saved in the file containing the manifest. Gets a value that indicates whether this assembly is held in a collectible AssemblyLoadContext. Gets a value that indicates whether the current assembly was generated dynamically in the current process by using reflection emit.

Gets a Boolean value indicating whether this assembly was loaded into the reflection-only context. Gets a value that indicates which set of security rules the common language runtime CLR enforces for this assembly. Locates the specified type from this assembly and creates an instance of it using the system activator, using case-sensitive search. Locates the specified type from this assembly and creates an instance of it using the system activator, with optional case-sensitive search.

Locates the specified type from this assembly and creates an instance of it using the system activator, with optional case-sensitive search and having the specified culture, arguments, and binding and activation attributes. Returns the Assembly of the method that invoked the currently executing method. Returns information about the attributes that have been applied to the current Assembly , expressed as CustomAttributeData objects.

Gets the process executable in the default application domain. In other application domains, this is the first executable that was executed by ExecuteAssembly String.

Gets a FileStream for the specified file in the file table of the manifest of this assembly. Gets the files in the file table of an assembly manifest, specifying whether to include resource modules.

Gets all the loaded modules that are part of this assembly, specifying whether to include resource modules. Loads the specified manifest resource, scoped by the namespace of the specified type, from this assembly. Gets all the modules that are part of this assembly, specifying whether to include resource modules. Gets an AssemblyName for this assembly. Gets an AssemblyName for this assembly, setting the codebase as specified by copiedName. Gets the AssemblyName objects for all the assemblies referenced by this assembly.

Gets the Type of the current instance. Gets the Type object with the specified name in the assembly instance. Gets the Type object with the specified name in the assembly instance and optionally throws an exception if the type is not found. Gets the Type object with the specified name in the assembly instance, with the options of ignoring the case, and of throwing an exception if the type is not found.

Loads an assembly given its AssemblyName. The assembly is loaded into the domain of the caller using the supplied evidence. Loads the assembly with a common object file format COFF -based image containing an emitted assembly. The assembly is loaded into the application domain of the caller.

Loads the assembly with a common object file format COFF -based image containing an emitted assembly, optionally including symbols for the assembly. Loads the assembly with a common object file format COFF -based image containing an emitted assembly, optionally including symbols and evidence for the assembly. Loads the assembly with a common object file format COFF -based image containing an emitted assembly, optionally including symbols and specifying the source for the security context.
