Csharp 为什么会出错'；日历请求生成器'；不包含'；请求'"；graphClient.Me.Calendars.Request().GetAsync()；

Graph SDK v4中使用了Request()方法，最新的SDK v5go 掉了这个方法，可以直接调用GetAsync()

await graphClient.Me.Calendars.GetAsync();

获取访问令牌(基于您的 comments )

• 创建一个实现IAccessTokenProvider的新类
• 在GetAuthorizationTokenAsync人中创造IPublicClientApplication人

public class TokenProvider : IAccessTokenProvider
{
    public AllowedHostsValidator AllowedHostsValidator => throw new NotImplementedException();

    public async Task<string> GetAuthorizationTokenAsync(Uri uri, Dictionary<string, object> additionalAuthenticationContext = null, CancellationToken cancellationToken = default)
    {
        var scopes = new[] { "Calendar.ReadWrite" };
        AuthenticationResult authResult;
        var publicClientApp = PublicClientApplicationBuilder.Create("clientId").Build();
        try
        {

            var accounts = await publicClientApp.GetAccountsAsync();
            authResult = await publicClientApp.AcquireTokenSilent(scopes, accounts.FirstOrDefault()).ExecuteAsync();
            return authResult.AccessToken;
        }
        catch (MsalUiRequiredException ex)
        {
            authResult = await publicClientApp.AcquireTokenInteractive(scopes).ExecuteAsync();
            return authResult.AccessToken;
        }
    }
}

现在，创建一个新的身份验证提供程序

var authenticationProvider = new BaseBearerTokenAuthenticationProvider(new TokenProvider());
var graphClient = new GraphServiceClient(authenticationProvider);
