DefineType Method (String, TypeAttributes, Type, Type[])

ModuleBuilder.DefineType Method (String, TypeAttributes, Type, Type[])

 

Constructs a TypeBuilder given the type name, attributes, the type that the defined type extends, and the interfaces that the defined type implements.

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

[ComVisibleAttribute(true)]
public TypeBuilder DefineType(
	string name,
	TypeAttributes attr,
	Type parent,
	Type[] interfaces
)

Parameters

name
Type: System.String

The full path of the type. name cannot contain embedded nulls.

attr
Type: System.Reflection.TypeAttributes

The attributes to be associated with the type.

parent
Type: System.Type

The type that the defined type extends.

interfaces
Type: System.Type[]

The list of interfaces that the type implements.

Return Value

Type: System.Reflection.Emit.TypeBuilder

A TypeBuilder created with all of the requested attributes.

Exception Condition
ArgumentException

A type with the given name exists in the parent assembly of this module.

-or-

Nested type attributes are set on a type that is not nested.

ArgumentNullException

name is null.

Type names must be unique within an assembly. You cannot have two types with the same name in two different modules of an assembly.

System_CAPS_noteNote

Starting with the .NET Framework 2.0 Service Pack 1, 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 .NET Framework 3.5 or later.

The following example creates a TypeBuilder in the current dynamic module using CreateType, builds and completes the type, and saves the assembly.

AssemblyName asmname = new AssemblyName();
asmname.Name = "assemfilename.exe";        
AssemblyBuilder asmbuild = System.Threading.Thread.GetDomain().
            DefineDynamicAssembly(asmname, AssemblyBuilderAccess.RunAndSave);
ModuleBuilder modbuild = asmbuild.DefineDynamicModule( "modulename",
   "assemfilename.exe" );
TypeBuilder typebuild1 = modbuild.DefineType( "typename" );
typebuild1.CreateType();
asmbuild.Save( "assemfilename.exe" );
