c# – 获取在应用程序域内启动的进程的程序集名称

导读:我有一个创建应用程序域并启动它的服务: this._appDomain = AppDomain.CreateDomain(this._appName,AppDomain.CurrentDomain.Evidence,appDomainSetup);this._startStopControllerToRun = (IStartStop)this._appDomain.CreateInstanceFromAndUnwrap(assembl
我有一个创建应用程序域并启动它的服务:
this._appDomain = AppDomain.CreateDomain(this._appName,AppDomain.CurrentDomain.Evidence,appDomainSetup); this._startStopControllerToRun = (IStartStop)this._appDomain.CreateInstanceFromAndUnwrap(assemblyName,this._fullyQualifiedClassName); this._startStopControllerToRun.Start(); 这已经很长时间了.问题是在此应用程序域内启动的控制器调用框架日志记录类.记录器获取条目程序集名称,并将其记录为事件日志中的源.这是记录器获取源(调用者)名称的方式: private static string GetSource() { try { var assembly = Assembly.GetEntryAssembly(); // GetEntryAssembly() can return null when called in the context of a unit test project. // That can also happen when called from an app hosted in IIS,or even a windows service. if (assembly == null) { // From https://stackoverflow.com/a/14165787/279516: assembly = new StackTrace().GetFrames().Last().GetMethod().Module.Assembly; } return assembly.GetName().Name; } catch { return "Unknown"; } } 在添加之前,如果检查,记录器将为源记录“未知”.经过一些研究,我在if块中添加了尝试.现在,记录器将“mscorlib”记录为源(条目程序集名称). 这是概述: 如何获取在域中运行的程序集(具有控制器)的名称? 注意:我也尝试了这个(下面),但是它给了我存在日志记录类的框架的名称(不是控制器在app域中运行的程序集的名称): assembly = Assembly.GetExecutingAssembly(); 解决方法
这可能是你想做的事情的一种方式.我在这里演示的是通过SetData和GetData方法向创建的AppDomain传递和接收元数据,因此忽略了我创建实际远程类型的方式.
using System; using System.Reflection; namespace ConsoleApplication13 { class Program { static void Main(string[] args) { AppDomain appDomain = AppDomain.CreateDomain("foo"); appDomain.SetData(FooUtility.SourceKey,FooUtility.SourceValue); IFoo foo = (IFoo)appDomain.CreateInstanceFromAndUnwrap(Assembly.GetEntryAssembly().Location,typeof(Foo).FullName); foo.DoSomething(); } } public static class FooUtility { public const string SourceKey = "Source"; public const string SourceValue = "Foo Host"; } public interface IFoo { void DoSomething(); } public class Foo : MarshalByRefObject,IFoo { public void DoSomething() { string source = AppDomain.CurrentDomain.GetData(FooUtility.SourceKey) as string; if (String.IsNullOrWhiteSpace(source)) source = "some default"; Console.WriteLine(source); } } } 哪个输出:
因此,在您的情况下,您可以将任何源元数据传递给AppDomain: this._appDomain = AppDomain.CreateDomain(this._appName,appDomainSetup); this._appDomain.SetData("Source","MyController"); this._startStopControllerToRun = (IStartStop)this._appDomain.CreateInstanceFromAndUnwrap(assemblyName,this._fullyQualifiedClassName); this._startStopControllerToRun.Start(); 并在您的GetSource方法中检查它的存在. private static string GetSource() { try { string source = AppDomain.CurrentDomain.GetData("Source") as string; if (!String.IsNullOrWhiteSpace(source)) return source; var assembly = Assembly.GetEntryAssembly(); // GetEntryAssembly() can return null when called in the context of a unit test project. // That can also happen when called from an app hosted in IIS,or even a windows service. if (assembly == null) { // From https://stackoverflow.com/a/14165787/279516: assembly = new StackTrace().GetFrames().Last().GetMethod().Module.Assembly; } return assembly.GetName().Name; } catch { return "Unknown"; } } 更新替代方案 您还可以声明一个公共接口方法,用于在目标域中的静态位置设置源. using System; using System.Reflection; namespace ConsoleApplication13 { class Program { static void Main(string[] args) { AppDomain appDomain = AppDomain.CreateDomain("foo"); IFoo foo = (IFoo)appDomain.CreateInstanceFromAndUnwrap(Assembly.GetEntryAssembly().Location,typeof(Foo).FullName); foo.SetSource("Foo Host"); foo.DoSomething(); } } public interface IFoo { void DoSomething(); void SetSource(string source); } public class Foo : MarshalByRefObject,IFoo { public void DoSomething() { string source = Foo.Source; if (String.IsNullOrWhiteSpace(source)) source = "some default"; Console.WriteLine(source); } public static string Source{get; private set;} public void SetSource(string source) { Foo.Source = source; } } } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
