SupportedOSPlatformAttribute 類別

定義

指出指定的平台或作業系統支援某個 API。Indicates that an API is supported for a specified platform or operating system. 如果已指定版本,則該 API 便無法從舊版中呼叫。If a version is specified, the API cannot be called from an earlier version. 可以套用多個屬性來表示多個作業系統支援。Multiple attributes can be applied to indicate support on multiple operating systems.

public ref class SupportedOSPlatformAttribute sealed : System::Runtime::Versioning::OSPlatformAttribute
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Enum | System.AttributeTargets.Event | System.AttributeTargets.Field | System.AttributeTargets.Method | System.AttributeTargets.Module | System.AttributeTargets.Property | System.AttributeTargets.Struct, AllowMultiple=true, Inherited=false)]
public sealed class SupportedOSPlatformAttribute : System.Runtime.Versioning.OSPlatformAttribute
[<System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Enum | System.AttributeTargets.Event | System.AttributeTargets.Field | System.AttributeTargets.Method | System.AttributeTargets.Module | System.AttributeTargets.Property | System.AttributeTargets.Struct, AllowMultiple=true, Inherited=false)>]

備註

呼叫端可以套用 SupportedOSPlatformAttribute 或使用防護,以防止呼叫不支援的作業系統上的 api。Callers can apply a SupportedOSPlatformAttribute or use guards to prevent calls to APIs on unsupported operating systems. 指定的平臺應該只指定一次。A given platform should only be specified once.

建構函式

SupportedOSPlatformAttribute(String)
