重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
返回已加载到应用程序域的只反射上下文中的程序集。
public:
cli::array <System::Reflection::Assembly ^> ^ ReflectionOnlyGetAssemblies();public System.Reflection.Assembly[] ReflectionOnlyGetAssemblies ();member this.ReflectionOnlyGetAssemblies : unit -> System.Reflection.Assembly[]Public Function ReflectionOnlyGetAssemblies () As Assembly()返回
- Assembly[]
Assembly 对象数组，表示加载到应用程序域的只反射上下文中的程序集。
例外
尝试对已卸载的应用程序域进行操作。
示例
下面的代码示例将System.dll程序集加载到执行上下文中，然后加载到仅反射上下文中。 这些 GetAssemblies 和 ReflectionOnlyGetAssemblies 方法用于显示加载到每个上下文中的程序集。
using namespace System;
using namespace System::Reflection;
#using <System.dll>
using namespace System::Timers;
using namespace System::Collections;
int main()
{
// Get the assembly display name for System.dll, the assembly
// that contains System.Timers.Timer. Note that this causes
// System.dll to be loaded into the execution context.
//
String^ displayName = Timer::typeid->Assembly->FullName;
// Load System.dll into the reflection-only context. Note that
// if you obtain the display name (for example, by running this
// example program), and enter it as a literal string in the
// preceding line of code, you can load System.dll into the
// reflection-only context without loading it into the execution
// context.
Assembly::ReflectionOnlyLoad( displayName );
// Display the assemblies loaded into the execution and
// reflection-only contexts. System.dll appears in both contexts.
//
Console::WriteLine( L"------------- Execution Context --------------" );
IEnumerator^ myEnum = AppDomain::CurrentDomain->GetAssemblies()->GetEnumerator();
while ( myEnum->MoveNext() )
{
Assembly^ a = safe_cast<Assembly^>(myEnum->Current);
Console::WriteLine( L"\t{0}", a->GetName() );
}
Console::WriteLine( L"------------- Reflection-only Context --------------" );

while ( myEnum1->MoveNext() )
{
Assembly^ a = safe_cast<Assembly^>(myEnum1->Current);
Console::WriteLine( L"\t{0}", a->GetName() );

注解
此方法返回已加载到仅反射上下文中的程序集。 若要获取已加载以供执行的程序集，请使用 GetAssemblies 该方法。
