Assembly 类
定义一个 Assembly，它是可重用、无版本冲突并且可自我描述的公共语言运行库应用程序构造块。
**命名空间:**System.Reflection
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
<SerializableAttribute> _
<ClassInterfaceAttribute(ClassInterfaceType.None)> _
<ComVisibleAttribute(True)> _
Public Class Assembly
Implements _Assembly, IEvidenceFactory, ICustomAttributeProvider, ISerializable
用法
Dim instance As Assembly
[SerializableAttribute]
[ClassInterfaceAttribute(ClassInterfaceType.None)]
[ComVisibleAttribute(true)]
public class Assembly : _Assembly, IEvidenceFactory, ICustomAttributeProvider,
ISerializable
[SerializableAttribute]
[ClassInterfaceAttribute(ClassInterfaceType::None)]
[ComVisibleAttribute(true)]
public ref class Assembly : _Assembly, IEvidenceFactory, ICustomAttributeProvider,
ISerializable
/** @attribute SerializableAttribute() */
/** @attribute ClassInterfaceAttribute(ClassInterfaceType.None) */
/** @attribute ComVisibleAttribute(true) */
public class Assembly implements _Assembly, IEvidenceFactory,
ICustomAttributeProvider, ISerializable
SerializableAttribute
ClassInterfaceAttribute(ClassInterfaceType.None)
ComVisibleAttribute(true)
public class Assembly implements _Assembly, IEvidenceFactory,
ICustomAttributeProvider, ISerializable
备注
程序集提供使运行库能够充分了解应用程序的内容并强制使用应用程序定义的版本控制和依赖项规则的结构。这些概念对解决版本控制问题和简化运行库应用程序的部署至关重要。
