AssemblyCollection Class

Represents a collection of AssemblyInfo objects. This class cannot be inherited.

Namespace:  System.Web.Configuration
Assembly:  System.Web (in System.Web.dll)

'Declaration
<ConfigurationCollectionAttribute(GetType(AssemblyInfo))> _
Public NotInheritable Class AssemblyCollection _
	Inherits ConfigurationElementCollection
'Usage
Dim instance As AssemblyCollection

The AssemblyCollection class does not refer to any actual element in the underlying configuration file. It is a construct that allows access to the assembly information it contains.

This section provides two code examples. The first demonstrates how to declaratively specify values for several properties of the AssemblyCollection class. The second demonstrates how to use members of the AssemblyCollection class.

The following configuration file example shows how to declaratively specify values for several properties of the AssemblyCollection class.

<system.web>
  <compilation> 
    <assemblies>
      <add assembly="mscorlib" />
      <add assembly="System, Version=2.0.0.0, Culture=neutral, 
        PublicKeyToken=b77a5c561934e089" />
      <add assembly="System.Configuration, Version=2.0.0.0, 
        Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      <add assembly="System.Web, Version=2.0.0.0, Culture=neutral,

        Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      <add assembly="System.EnterpriseServices, Version=2.0.0.0, 
        Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      <add assembly="System.Web.Mobile, Version=2.0.0.0, 
        Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
      <add assembly="System.Web.UI.MobileControls.Adapters,

The following code example demonstrates how to use members of the AssemblyCollection class.
