RoleStore<TRole,TContext,TKey,TUserRole,TRoleClaim>.FindByIdAsync 方法

定义

查找具有指定 ID 作为异步操作的角色。

public virtual System.Threading.Tasks.Task<TRole> FindByIdAsync (string id, System.Threading.CancellationToken cancellationToken = default);
public virtual System.Threading.Tasks.Task<TRole?> FindByIdAsync (string id, System.Threading.CancellationToken cancellationToken = default);
abstract member FindByIdAsync : string * System.Threading.CancellationToken -> System.Threading.Tasks.Task<'Role (requires 'Role :> Microsoft.AspNetCore.Identity.EntityFrameworkCore.IdentityRole<'Key, 'UserRole, 'RoleClaim>)>
override this.FindByIdAsync : string * System.Threading.CancellationToken -> System.Threading.Tasks.Task<'Role (requires 'Role :> Microsoft.AspNetCore.Identity.EntityFrameworkCore.IdentityRole<'Key, 'UserRole, 'RoleClaim>)>
abstract member FindByIdAsync : string * System.Threading.CancellationToken -> System.Threading.Tasks.Task<'Role (requires 'Role :> Microsoft.AspNetCore.Identity.IdentityRole<'Key>)>
override this.FindByIdAsync : string * System.Threading.CancellationToken -> System.Threading.Tasks.Task<'Role (requires 'Role :> Microsoft.AspNetCore.Identity.IdentityRole<'Key>)>
Public Overridable Function FindByIdAsync (id As String, Optional cancellationToken As CancellationToken = Nothing) As Task(Of TRole)

参数

id
String

要查找的角色 ID。

cancellationToken
