Initializes a new instance of the AssemblyName class.

Overloads

AssemblyName()	Initializes a new instance of the AssemblyName class.
AssemblyName(String)	Initializes a new instance of the AssemblyName class with the specified display name.

AssemblyName()

Source:

AssemblyName.cs

Initializes a new instance of the AssemblyName class.

public:
 AssemblyName();

public AssemblyName ();

Public Sub New ()

Examples

The following example creates a dynamic assembly named MyAssembly.exe and saves it to your hard disk. After running the example, you can use the Ildasm.exe (IL Disassembler) to examine the assembly metadata.

using namespace System;
using namespace System::Reflection;
using namespace System::Threading;
using namespace System::Reflection::Emit;
static void MakeAssembly( AssemblyName^ myAssemblyName, String^ fileName )
{
   // Get the assembly builder from the application domain associated with the current thread.
   AssemblyBuilder^ myAssemblyBuilder = Thread::GetDomain()->DefineDynamicAssembly( myAssemblyName, AssemblyBuilderAccess::RunAndSave );

   // Create a dynamic module in the assembly.
   ModuleBuilder^ myModuleBuilder = myAssemblyBuilder->DefineDynamicModule( "MyModule", fileName );

   // Create a type in the module.
   TypeBuilder^ myTypeBuilder = myModuleBuilder->DefineType( "MyType" );

   // Create a method called 'Main'.
   MethodBuilder^ myMethodBuilder = myTypeBuilder->DefineMethod( "Main", static_cast<MethodAttributes>(MethodAttributes::Public | MethodAttributes::HideBySig | MethodAttributes::Static), void::typeid, nullptr );

   // Get the Intermediate Language generator for the method.
   ILGenerator^ myILGenerator = myMethodBuilder->GetILGenerator();

   // Use the utility method to generate the IL instructions that print a String* to the console.
   myILGenerator->EmitWriteLine( "Hello World!" );

   // Generate the 'ret' IL instruction.
   myILGenerator->Emit( OpCodes::Ret );

   // End the creation of the type.
   myTypeBuilder->CreateType();

   // Set the method with name 'Main' as the entry point in the assembly.
   myAssemblyBuilder->SetEntryPoint( myMethodBuilder );
   myAssemblyBuilder->Save( fileName );
}

int main()
{
   // Create a dynamic assembly with name 'MyAssembly' and build version '1.0.0.2001'.
   AssemblyName^ myAssemblyName = gcnew AssemblyName;
   myAssemblyName->Name = "MyAssembly";
   myAssemblyName->Version = gcnew Version( "1.0.0.2001" );
   MakeAssembly( myAssemblyName, "MyAssembly.exe" );

   // Get all the assemblies currently loaded in the application domain.
   array<Assembly^>^myAssemblies = Thread::GetDomain()->GetAssemblies();

   // Get the dynamic assembly named 'MyAssembly'. 
   Assembly^ myAssembly = nullptr;
   for ( int i = 0; i < myAssemblies->Length; i++ )
   {
      if ( String::Compare( myAssemblies[ i ]->GetName()->Name, "MyAssembly" ) == 0 )
            myAssembly = myAssemblies[ i ];

AssemblyName(String)

Source:

AssemblyName.cs

Initializes a new instance of the AssemblyName class with the specified display name.

public:
 AssemblyName(System::String ^ assemblyName);

public AssemblyName (string assemblyName);

new System.Reflection.AssemblyName : string -> System.Reflection.AssemblyName

Public Sub New (assemblyName As String)

Parameters

assemblyName

String

The display name of the assembly, as returned by the FullName property.

Exceptions

ArgumentNullException

assemblyName is null.

ArgumentException

assemblyName is a zero-length string.

FileLoadException

The referenced assembly could not be found, or could not be loaded.

Note: In .NET for Windows Store apps or the Portable Class Library, catch the base class exception, IOException, instead.

Examples

The following example creates an instance of AssemblyName from a display name. The individual elements of the display name are output to the console as properties of the AssemblyName object.

using namespace System;
using namespace System::Reflection;

int main()
{
   // Create an AssemblyName, specifying the display name, and then
   // print the properties.
   AssemblyName^ myAssemblyName = 
      gcnew AssemblyName("Example, Version=1.0.0.2001, Culture=en-US, PublicKeyToken=null");
   Console::WriteLine("Name: {0}", myAssemblyName->Name);
   Console::WriteLine("Version: {0}", myAssemblyName->Version);
   Console::WriteLine("CultureInfo: {0}", myAssemblyName->CultureInfo);
   Console::WriteLine("FullName: {0}", myAssemblyName->FullName);
}
/* This code example produces output similar to the following:

Name: Example
Version: 1.0.0.2001
CultureInfo: en-US
FullName: Example, Version=1.0.0.2001, Culture=en-US, PublicKeyToken=null
 */

using System;
using System.Reflection;

   {
      // Create an AssemblyName, specifying the display name, and then
      // print the properties.
      AssemblyName myAssemblyName =
         new AssemblyName("Example, Version=1.0.0.2001, Culture=en-US, PublicKeyToken=null");
      Console.WriteLine("Name: {0}", myAssemblyName.Name);
      Console.WriteLine("Version: {0}", myAssemblyName.Version);
      Console.WriteLine("CultureInfo: {0}", myAssemblyName.CultureInfo);
      Console.WriteLine("FullName: {0}", myAssemblyName.FullName);
   }

      Dim myAssemblyName As New _

Remarks

The supplied assemblyName is parsed, and the appropriate fields of the new AssemblyName are initialized with values from the display name. This is the recommended way of parsing display names. Writing your own code to parse display names is not recommended.
