Voorbeelden

In het volgende voorbeeld wordt een dynamische assembly gemaakt met de naam MyAssembly.exe en opgeslagen op de harde schijf. Nadat u het voorbeeld hebt uitgevoerd, kunt u de Ildasm.exe (IL Disassembler) gebruiken om de metagegevens van de assembly te onderzoeken.

using System;
using System.Reflection;
using System.Threading;
using System.Reflection.Emit;

public class AssemblyName_Constructor
{
   public 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", MethodAttributes.Public | MethodAttributes.HideBySig |
         MethodAttributes.Static, typeof(void), null);
      // 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);
   }

   public static void Main()
   {
      // Create a dynamic assembly with name 'MyAssembly' and build version '1.0.0.2001'.
      AssemblyName myAssemblyName = new AssemblyName();

      myAssemblyName.Version = new Version("1.0.0.2001");
      MakeAssembly(myAssemblyName, "MyAssembly.exe");

      // Get all the assemblies currently loaded in the application domain.
      Assembly[] myAssemblies = Thread.GetDomain().GetAssemblies();

      // Get the dynamic assembly named 'MyAssembly'.

      {
         Console.WriteLine("\nDisplaying the assembly name\n");
         Console.WriteLine(myAssembly);
      }

AssemblyName(String)

Bron:

AssemblyName.cs

Initialiseert een nieuw exemplaar van de AssemblyName klasse met de opgegeven weergavenaam.

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

De weergavenaam van de assembly, zoals geretourneerd door de FullName eigenschap.

Uitzonderingen

ArgumentNullException

assemblyName is null.

ArgumentException

assemblyName is een tekenreeks met lengte nul.

FileLoadException

Kan de assembly waarnaar wordt verwezen niet vinden of kan niet worden geladen.

Opmerking: In .NET voor Windows Store-apps of de Portable Class Library, haalt u in plaats daarvan de uitzondering van de basisklasse op, IOException.

Voorbeelden

In het volgende voorbeeld wordt een exemplaar van AssemblyName een weergavenaam gemaakt. De afzonderlijke elementen van de weergavenaam worden als eigenschappen van het AssemblyName object naar de console uitgevoerd.

using System;
using System.Reflection;

public class AssemblyNameDemo
{
   public static void Main()
   {
      // 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);
   }
}
/* 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
 */

Imports System.Reflection

Public Class AssemblyNameDemo
   
   Public Shared Sub Main()
 
      ' Create an AssemblyName, specifying the display name, and then
      ' print the properties.
      Dim myAssemblyName As 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)

   End Sub  
End Class 

' 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

Opmerkingen

De opgegeven assemblyName gegevens worden geparseerd en de juiste velden van de nieuwe AssemblyName worden geïnitialiseerd met waarden uit de weergavenaam. Dit is de aanbevolen manier om weergavenamen te parseren. Het is niet raadzaam om uw eigen code te schrijven om weergavenamen te parseren.
