Microsoft Graph - Outlook Api -如何获取所创建事件的id？

using Microsoft.Graph;
using Microsoft.Identity.Client;
using System;

// 创建事件并获取id
public async Task<string> CreateEventAndGetId()
{
    // 配置应用程序的身份验证信息
    var clientId = "YourClientId";
    var clientSecret = "YourClientSecret";
    var tenantId = "YourTenantId";
    var authority = $"https://login.microsoftonline.com/{tenantId}";
    var scopes = new[] { "https://graph.microsoft.com/.default" };

    // 创建身份验证提供程序
    var app = ConfidentialClientApplicationBuilder
        .Create(clientId)
        .WithClientSecret(clientSecret)
        .WithAuthority(authority)
        .Build();

    // 获取访问令牌
    var authResult = await app.AcquireTokenForClient(scopes).ExecuteAsync();

    // 创建GraphServiceClient实例
    var graphClient = new GraphServiceClient(new DelegateAuthenticationProvider((requestMessage) =>
    {
        requestMessage.Headers.Authorization = new AuthenticationHeaderValue("Bearer", authResult.AccessToken);
        return Task.FromResult(0);
    }));

    // 创建事件
    var newEvent = new Event
    {
        Subject = "New Event",
        Start = new DateTimeTimeZone { DateTime = "2022-01-01T09:00:00", TimeZone = "UTC" },
        End = new DateTimeTimeZone { DateTime = "2022-01-01T10:00:00", TimeZone = "UTC" }
    };

    var createdEvent = await graphClient.Me.Events.Request().AddAsync(newEvent);

    // 获取所创建事件的id
    var eventId = createdEvent.Id;

    return eventId;
}
