i tried msdn method with dynamically load\unload assembly to domain, but it
still eat much memory
my code is
Bitmap b = new Bitmap(@"d:\0.bmp");
AppDomainSetup setup = new AppDomainSetup();
// setup.ApplicationBase = @"c:\temp\";
AssemblyName assName = AssemblyName.GetAssemblyName(ass);
Evidence baseEvidence = AppDomain.CurrentDomain.Evidence;
Evidence evidence = new Evidence(baseEvidence);
AppDomain newDomain = AppDomain.CreateDomain("newDomain",
evidence, setup);
Assembly a = newDomain.Load(assName);
Type myType = a.GetType("tessnet2.Tesseract");
MethodInfo mymethod = myType.GetMethod("Init");
Object obj = Activator.CreateInstance(myType);
mymethod.Invoke(obj, new object[] { null, "eng", false });
mymethod = myType.GetMethod("DoOCR");
obj = Activator.CreateInstance(myType);
object o = mymethod.Invoke(obj, new object[] { b,
Rectangle.Empty });
label1.Text = ((List<tessnet2.Word>)o)[0].Text;
AppDomain.Unload(newDomain);
