System.AppDomain.SetShadowCopyPath 方法

System.AppDomain.SetShadowCopyPath 方法例子

此方法现已过时，不应当用于新的开发工作。

using System;
using System.Security.Policy;  //for evidence object
namespace AppDomainSnippets
{
	class ADShadowCopy
	{
		static void Main(string[] args)
		{

			AppDomainSetup setup = new AppDomainSetup();
			// Shadow copying will not work unless the application has a name.
			setup.ApplicationName = "MyApplication";

			//Create evidence for the new application domain from evidence of
			// current application domain.
			Evidence adevidence = AppDomain.CurrentDomain.Evidence;
			
			// Create a new application domain.
			AppDomain domain = AppDomain.CreateDomain("MyDomain", adevidence, setup);
			
			// MyAssembly.dll is located in the Assemblies subdirectory.
			domain.AppendPrivatePath("Assemblies");
			// MyOtherAssembly.dll and MyThirdAssembly.dll are located in the
			// MoreAssemblies subdirectory.
			domain.AppendPrivatePath("MoreAssemblies");
			// Display the relative search path.
			Console.WriteLine("RelativeSearchPath: " + domain.RelativeSearchPath);
			// Because Load returns an Assembly object, the assemblies must be
			// loaded into the current domain as well. This will fail unless the
			// current domain also has these directories in its search path.
			AppDomain.CurrentDomain.AppendPrivatePath("Assemblies");
			AppDomain.CurrentDomain.AppendPrivatePath("MoreAssemblies");
			
			// Save shadow copies to C:\Cache
			domain.SetCachePath("C:\\Cache");
			// Shadow copy only the assemblies in the Assemblies directory.
			domain.SetShadowCopyPath(domain.BaseDirectory + "Assemblies");
			// Turn shadow copying on.
			domain.SetShadowCopyFiles();
			
			// This will be copied.
			// You must supply a valid fully qualified assembly name here. 
			domain.Load("Assembly1 text name, Version, Culture, PublicKeyToken");
			// This will not be copied.
			// You must supply a valid fully qualified assembly name here. 
			domain.Load("Assembly2 text name, Version, Culture, PublicKeyToken");
			
			// When the shadow copy path is cleared, the CLR will make shadow copies
			// of all private assemblies.
			domain.ClearShadowCopyPath();
			// MoreAssemblies\MyThirdAssembly.dll should be shadow copied this time.
			// You must supply a valid fully qualified assembly name here.
			domain.Load("Assembly3 text name, Version, Culture, PublicKeyToken");
			
			// Unload the domain.
			AppDomain.Unload(domain);
		}
	}
}
