ModuleBuilder.DefineType Method (String, TypeAttributes)

 

Constructs a TypeBuilder given the type name and the type attributes.

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

Public Function DefineType (
	name As String,
	attr As TypeAttributes
) As TypeBuilder

Parameters

name
Type: System.String

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

attr
Type: System.Reflection.TypeAttributes

The attributes of the defined type.

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.

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