AssemblyBuilder.DefineDynamicModule Method (String)

Defines a named transient dynamic module in this assembly.

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

public ModuleBuilder DefineDynamicModule (
	string name
)
public ModuleBuilder DefineDynamicModule (
	String name
)
public function DefineDynamicModule (
	name : String
) : ModuleBuilder
Not applicable.

Parameters

name

The name of the dynamic module. Must be less than 260 characters in length.

Return Value

A ModuleBuilder representing the defined dynamic module.

Exception typeCondition

ArgumentException

name begins with white space.

-or-

The length of name is zero.

-or-

The length of name is greater than or equal to 260.

ArgumentNullException

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

SecurityException

The caller does not have the required permission.

ExecutionEngineException

The assembly for default symbol writer cannot be loaded.

-or-

The type that implements the default symbol writer interface cannot be found.

It is an error to define multiple dynamic modules with the same name in an assembly.

The defined dynamic module is transient. The dynamic module is not saved, even if the parent dynamic assembly was created with RunAndSave.

NoteNote:

To suppress optimizations when debugging dynamic modules, apply the DebuggableAttribute attribute to the dynamic assembly before calling DefineDynamicModule. Create an instance of DebuggableAttribute with the DisableOptimizations flag and apply it using the SetCustomAttribute method. The attribute must be applied to the dynamic assembly. It has no effect if applied to the module.

NoteNote:

Starting with the , this member no longer requires ReflectionPermission with the ReflectionPermissionFlag.ReflectionEmit flag. (See Security Issues in Reflection Emit.) To use this functionality, your application should target the . For more information, see The .NET Framework 3.5 Architecture.

The code example below demonstrates how to create a transient dynamic module using DefineDynamicModule.

AppDomain myAppDomain = Thread.GetDomain(); 
AssemblyName myAsmName = new AssemblyName();
myAsmName.Name = "MyAssembly";
AssemblyBuilder myAsmBuilder = myAppDomain.DefineDynamicAssembly(
                     myAsmName,
                     AssemblyBuilderAccess.Run);

// Create a transient dynamic module. Since no DLL name is specified with
// this constructor, it can not be saved. 
ModuleBuilder myModuleBuilder = myAsmBuilder.DefineDynamicModule("MyModule1");

AppDomain myAppDomain = System.Threading.Thread.GetDomain();
AssemblyName myAsmName = new AssemblyName();
myAsmName.set_Name("MyAssembly");
AssemblyBuilder myAsmBuilder = myAppDomain.DefineDynamicAssembly(
    myAsmName, AssemblyBuilderAccess.Run);

// Create a transient dynamic module. Since no DLL name is specified 
// with this constructor, it can not be saved. 
ModuleBuilder myModuleBuilder = 
    myAsmBuilder.DefineDynamicModule("MyModule1");
