Assembly.GetExecutingAssembly Assembly.GetExecutingAssembly Assembly.GetExecutingAssembly Assembly.GetExecutingAssembly Method

定义

获取包含当前执行的代码的程序集。Gets the assembly that contains the code that is currently executing.

public:
 static System::Reflection::Assembly ^ GetExecutingAssembly();
public static System.Reflection.Assembly GetExecutingAssembly ();
static member GetExecutingAssembly : unit -> System.Reflection.Assembly
Public Shared Function GetExecutingAssembly () As Assembly

返回

包含当前执行的代码的程序集。The assembly that contains the code that is currently executing.

示例

下面的示例使用Type.Assembly属性, 基于该程序集中包含的类型获取当前正在执行的程序集。The following example uses the Type.Assembly property to get the currently executing assembly based on a type contained in that assembly. 它还会调用GetExecutingAssembly方法, 以显示该方法Assembly返回一个表示同一程序集的对象。It also calls the GetExecutingAssembly method to show that it returns an Assembly object that represents the same assembly.

using namespace System;
using namespace System::Reflection;

ref class Example
{};

void main()
{
   // Get the assembly from a known type in that assembly.
   Type^ t = Example::typeid;
   Assembly^ assemFromType = t->Assembly;
   Console::WriteLine("Assembly that contains Example:");
   Console::WriteLine("   {0}\n", assemFromType->FullName);

   // Get the currently executing assembly.
   Assembly^ currentAssem = Assembly::GetExecutingAssembly();
   Console::WriteLine("Currently executing assembly:");
   Console::WriteLine("   {0}\n", currentAssem->FullName);

   Console::WriteLine("The two Assembly objects are equal: {0}",
                      assemFromType->Equals(currentAssem));
}
// The example displays the following output:
//    Assembly that contains Example:
//       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
//
//    Currently executing assembly:
//       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
//
//    The two Assembly objects are equal: True
using System;
using System.Reflection;

class Example
{
   static void Main()
   {
      // Get the assembly from a known type in that assembly.
      Type t = typeof(Example);
      Assembly assemFromType = t.Assembly;
      Console.WriteLine("Assembly that contains Example:");
      Console.WriteLine("   {0}\n", assemFromType.FullName);

      // Get the currently executing assembly.
      Assembly currentAssem = Assembly.GetExecutingAssembly();
      Console.WriteLine("Currently executing assembly:");
      Console.WriteLine("   {0}\n", currentAssem.FullName);
      
      Console.WriteLine("The two Assembly objects are equal: {0}",
                        assemFromType.Equals(currentAssem));
   }
}
// The example displays the following output:
//    Assembly that contains Example:
//       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
//
//    Currently executing assembly:
//       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
//
//    The two Assembly objects are equal: True
Imports System.Reflection

Public Module Example
   Public Sub Main()
      ' Get the assembly from a known type in that assembly.
      Dim t As Type = GetType(Example)
      Dim assemFromType As Assembly = t.Assembly
      Console.WriteLine("Assembly that contains Example:")
      Console.WriteLine("   {0}", assemFromType.FullName)
      Console.WriteLine()
      
      ' Get the currently executing assembly.
      Dim currentAssem As Assembly = Assembly.GetExecutingAssembly()
      Console.WriteLine("Currently executing assembly:")
      Console.WriteLine("   {0}", currentAssem.FullName)
      Console.WriteLine()
      
      Console.WriteLine("The two Assembly objects are equal: {0}",
                        assemFromType.Equals(currentAssem))
   End Sub
End Module
' The example displays the following output:
'    Assembly that contains Example:
'       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
'
'    Currently executing assembly:
'       GetExecutingAssembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
'
'    The two Assembly objects are equal: True

注解

出于性能方面的原因, 只有在设计时不知道当前正在执行的程序集时, 才应调用此方法。For performance reasons, you should call this method only when you do not know at design time what assembly is currently executing. 检索Assembly表示当前程序集的对象的建议方法是Type.Assembly使用在程序集中找到的类型的属性, 如下面的示例所示。The recommended way to retrieve an Assembly object that represents the current assembly is to use the Type.Assembly property of a type found in the assembly, as the following example illustrates.

using System;
using System.Reflection;

public class Example
{
   public static void Main()
   {
      Assembly assem = typeof(Example).Assembly;
      Console.WriteLine("Assembly name: {0}", assem.FullName);
   }
}
// The example displays output like the following:
//    Assembly name: Assembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null
Imports System.Reflection

Module Example
   Public Sub Main()
      Dim assem As Assembly = GetType(Example).Assembly
      Console.WriteLine("Assembly name: {0}", assem.FullName)
   End Sub
End Module
' The example displays the following output:
'   Assembly name: Assembly1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null

若要获取包含调用当前正在执行的代码的方法的程序集, GetCallingAssembly请使用。To get the assembly that contains the method that called the currently executing code, use GetCallingAssembly.
