AppDomain.DefineDynamicAssembly Method (AssemblyName, AssemblyBuilderAccess, String, Boolean, IEnumerable(CustomAttributeBuilder))

.NET Framework 4.6 and 4.5

Defines a dynamic assembly using the specified name, access mode, storage directory, and synchronization option.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

member DefineDynamicAssembly : 
        name:AssemblyName * 
        access:AssemblyBuilderAccess * 
        dir:string * 
        isSynchronized:bool * 
        assemblyAttributes:IEnumerable<CustomAttributeBuilder> -> AssemblyBuilder

Parameters

name
Type: System.Reflection.AssemblyName

The unique identity of the dynamic assembly.

access
Type: System.Reflection.Emit.AssemblyBuilderAccess

The mode in which the dynamic assembly will be accessed.

dir
Type: System.String

The name of the directory where the dynamic assembly will be saved. If dir is a null reference (Nothing in Visual Basic), the current directory is used.

isSynchronized
Type: System.Boolean

true to synchronize the creation of modules, types, and members in the dynamic assembly; otherwise, false.

assemblyAttributes
Type: System.Collections.Generic.IEnumerable(CustomAttributeBuilder)

An enumerable list of attributes to be applied to the assembly, or a null reference (Nothing in Visual Basic) if there are no attributes.

Return Value

Type: System.Reflection.Emit.AssemblyBuilder
A dynamic assembly with the specified name and features.

ExceptionCondition
ArgumentNullException

name is a null reference (Nothing in Visual Basic).

ArgumentException

The Name property of name is a null reference (Nothing in Visual Basic).

-or-

The Name property of name starts with white space, or contains a forward or backward slash.

AppDomainUnloadedException

The operation is attempted on an unloaded application domain.

Use this method overload to specify attributes that do not work correctly unless they are applied when a dynamic assembly is created. For example, security attributes such as SecurityTransparentAttribute and SecurityCriticalAttribute do not work correctly if they are added after a dynamic assembly has been created.

If isSynchronized is true, the following methods of the resulting AssemblyBuilder will be synchronized: DefineDynamicModule, DefineResource, AddResourceFile, GetDynamicModule, SetEntryPoint, and Save. If two of these methods are called on different threads, one will block until the other is completed.
