AppDomainSetup.DynamicBase プロパティ

動的に生成されたファイルが格納されるディレクトリのベース ディレクトリを取得または設定します。

名前空間: System
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public Property DynamicBase As
 String

Visual Basic (使用法)

Dim instance As AppDomainSetup
Dim value As String

value = instance.DynamicBase

instance.DynamicBase = value

C#

public string DynamicBase { get;
 set; }

C++

public:
virtual property String^ DynamicBase {
    String^ get () sealed;
    void set (String^ value) sealed;
}

J#

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

/** @property */
public final void set_DynamicBase (String value)

JScript

public final function get
 DynamicBase () : String

public final function set
 DynamicBase (value : String)

プロパティ値
AppDomain.DynamicDirectory の格納ディレクトリを指定する String。

解説

AppDomain を作成すると、Dynamic Directory というディレクトリを動的アセンブリの格納用として指定できます。このディレクトリの論理的な位置は ApplicationBase ですが、同ディレクトリの別の部分にも配置できます。
