DefaultCharSetAttribute 類別

定義

指定 CharSet 列舉型別的值。Specifies the value of the CharSet enumeration. 此類別無法被繼承。This class cannot be inherited.

public ref class DefaultCharSetAttribute sealed : Attribute
[System.AttributeUsage(System.AttributeTargets.Module, Inherited=false)]
[System.Runtime.InteropServices.ComVisible(true)]
public sealed class DefaultCharSetAttribute : Attribute
type DefaultCharSetAttribute = class
    inherit Attribute
Public NotInheritable Class DefaultCharSetAttribute
Inherits Attribute
繼承
DefaultCharSetAttribute
屬性

範例

下列程式碼範例會將預設 CharSet 值從 Ansi 變更為 AutoThe following code example changes the default CharSet value from Ansi to Auto.

using System.Runtime.InteropServices;

[module: DefaultCharSet(CharSet.Auto)]

// …

備註

在元件層級或模組層級套用 DefaultCharSetAttribute 屬性,以設定任何呼叫 DllImportAttributeCharSet 值,而不包含使用者所指定的 CharSet 具名引數。Apply the DefaultCharSetAttribute attribute at the assembly level or module level to set the CharSet value for any call to DllImportAttribute that does not include a CharSet named argument specified by the user.

使用者指定的 CharSet 具名引數會覆寫 DefaultCharSetAttribute的設定。A CharSet named argument specified by the user overrides the setting of DefaultCharSetAttribute.

注意

只有C#和 Visual Basic 編譯器會辨識此屬性;C++編譯器不會使用它。Only the C# and Visual Basic compilers recognize this attribute; it is not used by the C++ compiler.

建構函式

DefaultCharSetAttribute(CharSet)

使用指定的 DefaultCharSetAttribute 值,初始化 CharSet 類別的新執行個體。Initializes a new instance of the DefaultCharSetAttribute class with the specified CharSet value.

屬性

CharSet

取得所有 CharSet 呼叫的 DllImportAttribute 預設值。Gets the default value of CharSet for any call to DllImportAttribute.

TypeId

在衍生類別中實作時,取得這個 Attribute 的唯一識別碼。When implemented in a derived class, gets a unique identifier for this Attribute.

(繼承來源 Attribute)

方法

Equals(Object)

傳回值,這個值指出此執行個體是否與指定的物件相等。Returns a value that indicates whether this instance is equal to a specified object.

(繼承來源 Attribute)
GetHashCode()

傳回這個執行個體的雜湊碼。Returns the hash code for this instance.

(繼承來源 Attribute)
GetType()

取得目前執行個體的 TypeGets the Type of the current instance.

(繼承來源 Object)
IsDefaultAttribute()

在衍生類別中覆寫時,表示這個執行個體的值是衍生類別的預設值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(繼承來源 Attribute)
Match(Object)

在衍生類別中覆寫時,會傳回值,表示這個執行個體是否等於指定物件。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(繼承來源 Attribute)
MemberwiseClone()

建立目前 Object 的淺層複製。Creates a shallow copy of the current Object.

(繼承來源 Object)
ToString()

傳回代表目前物件的字串。Returns a string that represents the current object.

(繼承來源 Object)

明確介面實作

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

將一組名稱對應至一組對應的分派識別項 (Dispatch Identifier)。Maps a set of names to a corresponding set of dispatch identifiers.

(繼承來源 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

擷取物件的類型資訊,可以用來取得介面的類型資訊。Retrieves the type information for an object, which can be used to get the type information for an interface.

(繼承來源 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

擷取物件提供的類型資訊介面數目 (0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(繼承來源 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

提供物件所公開的屬性和方法的存取權。Provides access to properties and methods exposed by an object.
