要使用具有属性的接口动态创建程序集,请执行以下操作:
using System.Reflection;
using System.Reflection.Emit;
// Need the output the assembly to a specific directory
string outputdir = "F:\\tmp\\";
string fname = "Hello.World.dll";
// Define the assembly name
AssemblyName bAssemblyName = new AssemblyName();
bAssemblyName.Name = "Hello.World";
bAssemblyName.Version = new system.Version(1,2,3,4);
// Define the new assembly and module
AssemblyBuilder bAssembly = System.AppDomain.CurrentDomain.DefineDynamicAssembly(bAssemblyName, AssemblyBuilderAccess.Save, outputdir);
ModuleBuilder bModule = bAssembly.DefineDynamicModule(fname, true);
TypeBuilder tInterface = bModule.DefineType("IFoo", TypeAttributes.Interface | TypeAttributes.Public);
ConstructorInfo con = typeof(FunAttribute).GetConstructor(new Type[] { typeof(string) });
CustomAttributeBuilder cab = new CustomAttributeBuilder(con, new object[] { "Hello" });
tInterface.SetCustomAttribute(cab);
Type tInt = tInterface.CreateType();
bAssembly.Save(fname);
这将产生以下结果:
namespace Hello.World
{
[Fun("Hello")]
public interface IFoo
{}
}
添加方法通过调用TypeBuilder.DefineMethod使用MethodBuilder类。
