assembly.CreateInstance メソッドを使用して型のインスタンスを作成しようとすると、例外が発生します。これは例外が発生する私のコードです
Assembly assembly = Assembly.LoadFrom(@"C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI\Microsoft.Office.Server.UserProfiles.dll");
Type type = assembly.GetType("Microsoft.Office.Server.UserProfiles.UserProfileManager");
object ins = assembly.CreateInstance(type.FullName);
