AppDomain.DynamicDirectory 属性

项目
08/17/2007

获取目录，它由程序集冲突解决程序用来探测动态创建的程序集。

**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）

语法

声明
Public ReadOnly Property DynamicDirectory As String
用法
Dim instance As AppDomain
Dim value As String

value = instance.DynamicDirectory

public string DynamicDirectory { get; }

public:
virtual property String^ DynamicDirectory {
    String^ get () sealed;
}

/** @property */
public final String get_DynamicDirectory ()

public final function get DynamicDirectory () : String

属性值

获取目录，它由程序集冲突解决程序用来探测动态创建的程序集。

异常

异常类型	条件
AppDomainUnloadedException	试图对已卸载的应用程序域进行操作。

备注

仅在尝试向此域中加载程序集之后，此属性才可用。
