Asp.net 如果我硬编码数据而不是使用查询，如何使用wait

我覆盖了OAuthAuthorizationServerProvider的两个方法，但是我正在硬编码数据，正如您在下面看到的那样。我如何使用wait？我可以在哪里应用，以便编译可以构建它

    public class MyAutorization : OAuthAuthorizationServerProvider
    {
        public override async Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
        {
            context.Validated();
        }
        public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
        {
            var identity = new ClaimsIdentity(context.Options.AuthenticationType);
            if (context.UserName == "admin" && context.Password == "admin")
            {
                identity.AddClaim(new Claim(ClaimTypes.Role, "admin"));
                identity.AddClaim(new Claim("username", "admin"));
                identity.AddClaim(new Claim(ClaimTypes.Name, "Mulla"));
                context.Validated(identity);
            }
            else if (context.UserName == "user" && context.Password == "user")
            {
                identity.AddClaim(new Claim(ClaimTypes.Role, "user"));
                identity.AddClaim(new Claim("username", "user"));
                identity.AddClaim(new Claim(ClaimTypes.Name, "Boland"));
                context.Validated(identity);
            }
            else
            {
                context.SetError("Access Denied", "Invalid User Name And Password");
                return;
            }
        }
    }

当您编写异步时，使用wait是必要的，但是使用旧的aproach可以做到这一点

public class MyAutorization : OAuthAuthorizationServerProvider
        {
            public override Task ValidateClientAuthentication(OAuthValidateClientAuthenticationContext context)
            {
                context.Validated();
                return Task.FromResult(0);
            }
            public override Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
            {
              //  await Task.CompletedTask
                var identity = new ClaimsIdentity(context.Options.AuthenticationType);
                if (context.UserName == "admin" && context.Password == "admin")
                {
                    identity.AddClaim(new Claim(ClaimTypes.Role, "admin"));
                    identity.AddClaim(new Claim("username", "admin"));
                    identity.AddClaim(new Claim(ClaimTypes.Name, "Mulla"));
                    context.Validated(identity);
                }
                else if (context.UserName == "user" && context.Password == "user")
                {
                    identity.AddClaim(new Claim(ClaimTypes.Role, "user"));
                    identity.AddClaim(new Claim("username", "user"));
                    identity.AddClaim(new Claim(ClaimTypes.Name, "Boland"));
                    context.Validated(identity);
                }
                else
                {
                    context.SetError("Access Denied", "Invalid User Name And Password");
                }
                return Task.FromResult(0);
            }
        }

对于较旧的框架，您可以删除

async

关键字并添加

return Task.CompletedTask

或

Task.FromResult（0）

versions@JSteward可以在旧版本中编辑以上代码吗？我不明白你的意思？@JSteward它对我有用，谢谢你的帮助任务。FromResult（0）完成了我的工作
