Gets the currently loaded assembly in which the specified type is defined.

public:
 static System::Reflection::Assembly ^ GetAssembly(Type ^ type);

public static System.Reflection.Assembly? GetAssembly (Type type);

public static System.Reflection.Assembly GetAssembly (Type type);

static member GetAssembly : Type -> System.Reflection.Assembly

Public Shared Function GetAssembly (type As Type) As Assembly

Parameters

type: Type

An object representing a type in the assembly that will be returned.

Returns

Assembly

The assembly in which the specified type is defined.

Exceptions

ArgumentNullException

type is null.

Examples

The following example retrieves the assembly that contains the Int32 type and displays its name and file location.

using namespace System;
using namespace System::Reflection;

void main()
{
   // Get a Type object.
   Type^ t = int::typeid;
   // Instantiate an Assembly class to the assembly housing the Integer type.
   Assembly^ assem = Assembly::GetAssembly(t);
   // Display the name of the assembly.
   Console::WriteLine("Name: {0}", assem->FullName);
   // Get the location of the assembly using the file: protocol.
   Console::WriteLine("CodeBase: {0}", assem->CodeBase);
}
// The example displays output like the following:
//    Name: mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
//    CodeBase: file:///C:/Windows/Microsoft.NET/Framework64/v4.0.30319/mscorlib.dll

using System;
using System.Reflection;

public class Example2
{
    public static void Main()
    {
        // Get a Type object.
        Type t = typeof(int);
        // Instantiate an Assembly class to the assembly housing the Integer type.
        Assembly assem = Assembly.GetAssembly(t);
        // Display the name of the assembly.
        Console.WriteLine("Name: {0}", assem.FullName);
        // Get the location of the assembly using the file: protocol.
        Console.WriteLine("CodeBase: {0}", assem.CodeBase);
    }
}
// The example displays output like the following:
//    Name: mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
//    CodeBase: file:///C:/Windows/Microsoft.NET/Framework64/v4.0.30319/mscorlib.dll

Imports System.Reflection

Module Example
   Public Sub Main()
      ' Get a Type object.
      Dim t As Type = GetType(Integer)
      ' Instantiate an Assembly class to the assembly housing the Integer type.
      Dim assem As Assembly = Assembly.GetAssembly(t)
      ' Display the name of the assembly.
      Console.WriteLine("Name: {0}", assem.FullName)
      ' Get the location of the assembly using the file: protocol.
      Console.WriteLine("CodeBase: {0}", assem.CodeBase)
   End Sub
End Module
' The example displays output like the following:
'    Name: mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
'    CodeBase: file:'/C:/Windows/Microsoft.NET/Framework64/v4.0.30319/mscorlib.dll

Remarks

Calling this method is equivalent to retrieving the value of the Type.Assembly property. However, the Type.Assembly property typically offers superior performance.

In order to call this method, you must have a Type object, which means that the assembly in which the class is defined must already be loaded.
