重载

NeedsEventData(EventDefinitionBase, Boolean, Boolean)	EventData根据DiagnosticSource给定事件是否启用了或 IDbContextLogger ，确定是否需要实例。
NeedsEventData<TInterceptor>(EventDefinitionBase, TInterceptor, Boolean, Boolean)	EventData根据DiagnosticSource给定事件是否启用了、 IDbContextLogger或 IInterceptor ，确定是否需要实例。

NeedsEventData(EventDefinitionBase, Boolean, Boolean)

EventData根据DiagnosticSource给定事件是否启用了或 IDbContextLogger ，确定是否需要实例。

public virtual bool NeedsEventData (Microsoft.EntityFrameworkCore.Diagnostics.EventDefinitionBase definition, out bool diagnosticSourceEnabled, out bool simpleLogEnabled);

abstract member NeedsEventData : Microsoft.EntityFrameworkCore.Diagnostics.EventDefinitionBase * bool * bool -> bool
override this.NeedsEventData : Microsoft.EntityFrameworkCore.Diagnostics.EventDefinitionBase * bool * bool -> bool

Public Overridable Function NeedsEventData (definition As EventDefinitionBase, ByRef diagnosticSourceEnabled As Boolean, ByRef simpleLogEnabled As Boolean) As Boolean

参数

definition: EventDefinitionBase

事件的定义。

diagnosticSourceEnabled: Boolean

如果已启用，DiagnosticSource则设置为 true ;false否则为。

simpleLogEnabled: Boolean

如果已启用，IDbContextLogger则为 true True;false否则为。

Boolean

true 如果启用了诊断源或 LogTo 记录器，则为 ; false 否则。

适用于

NeedsEventData<TInterceptor>(EventDefinitionBase, TInterceptor, Boolean, Boolean)

EventData根据DiagnosticSource给定事件是否启用了、 IDbContextLogger或 IInterceptor ，确定是否需要实例。

public virtual bool NeedsEventData<TInterceptor> (Microsoft.EntityFrameworkCore.Diagnostics.EventDefinitionBase definition, out TInterceptor interceptor, out bool diagnosticSourceEnabled, out bool simpleLogEnabled) where TInterceptor : class, Microsoft.EntityFrameworkCore.Diagnostics.IInterceptor;

public virtual bool NeedsEventData<TInterceptor> (Microsoft.EntityFrameworkCore.Diagnostics.EventDefinitionBase definition, out TInterceptor? interceptor, out bool diagnosticSourceEnabled, out bool simpleLogEnabled) where TInterceptor : class, Microsoft.EntityFrameworkCore.Diagnostics.IInterceptor;

abstract member NeedsEventData : Microsoft.EntityFrameworkCore.Diagnostics.EventDefinitionBase * 'Interceptor * bool * bool -> bool (requires 'Interceptor : null and 'Interceptor :> Microsoft.EntityFrameworkCore.Diagnostics.IInterceptor)
override this.NeedsEventData : Microsoft.EntityFrameworkCore.Diagnostics.EventDefinitionBase * 'Interceptor * bool * bool -> bool (requires 'Interceptor : null and 'Interceptor :> Microsoft.EntityFrameworkCore.Diagnostics.IInterceptor)

Public Overridable Function NeedsEventData(Of TInterceptor As {Class, IInterceptor}) (definition As EventDefinitionBase, ByRef interceptor As TInterceptor, ByRef diagnosticSourceEnabled As Boolean, ByRef simpleLogEnabled As Boolean) As Boolean
