MethodBuilder

System.Reflection.Emit (mscorlib.dll)

sealed class

This class represents a dynamically created method. Methods are created with TypeBuilder.DefineMethod( ) . When creating a method, specify the name , parameters, and return type. You can also specify other characteristics of the method, such as whether it is static, abstract, or virtual, by using the System.Reflection.MethodAttributes enumeration. After creating a method, you can specify how the return value will be marshaled to unmanaged code using SetMarshal( ) , and add declarative security using AddDeclarativeSecurity( ) . You must specify the security action (such as Demand, Assert, Deny) using the System.Security.Permissions.SecurityAction enumeration and the permissions required using the System.Security.PermissionSet collection class. You can call AddDeclarativeSecurity( ) several times to specify different security actions.

To create a global method builder, use ModuleBuilder.DefineGlobalMethod( ) . You must also use ModuleBuilder.CreateGlobalFunctions( ) to finish creating global methods before you persist or use the dynamic module. Global methods must be static. You can also create a global native method using ModuleBuilder.DefinePInvokeMethod( ) . PInvoke methods cannot be abstract or virtual.
