This is a copy paste from my original posted github issue

我正在开发一个利用 Microsoft.Graph SDK 的原型应用程序。我注意到，如果我在“实时”/个人 OneDrive 帐户上运行以下代码，它就可以正常工作并返回我期望的文件。但是，如果我对我的 OneDrive for Business 运行相同的代码，它会在 Microsoft.Graph.Core 中引发内部异常。我怀疑原因是我的搜索 URL 包含错误中提到的 *，但为什么它在搜索真实帐户时有效，而在搜索工作帐户时中断？

示例代码片段：

var graphserviceClient = new GraphServiceClient(
         new DelegateAuthenticationProvider(
             (requestMessage) =>
             {
                 requestMessage.Headers.Authorization = new AuthenticationHeaderValue("bearer", ADALAuth.CurrentAccessToken);

                 return Task.FromResult(0);
             }));

            var drive = graphserviceClient.Me.Drive.Request().GetAsync().Result;
            var collection = graphserviceClient.Me.Drive.Search("*.xyz").Request().GetAsync().GetAwaiter().GetResult();

返回的错误信息是：

Code: UnknownError
Message: A potentially dangerous Request.Path value was detected from the client (*).

Inner error

【解决方案1】：

在幕后，Graph 会根据您的帐户类型将您的请求路由到两个不同的系统。因此，这两个系统之间存在一些细微的差异。

无论如何，您不应该需要*，因为搜索已经在搜索您在其他字符串中传递的字符串。换句话说，*.xyz 和 .xyz 都被翻译成 *.xyz*。它将以这种方式在包括文件名、元数据和文件内容在内的多个字段中匹配此查询。

【讨论】：

因此，如果我想根据文件扩展名搜索并仅返回特定的 OneDrive 文件，我将不得不搜索 .xyz，然后根据文件名结尾过滤响应？
正确。作为回调的一部分，我通常对文件名执行正则表达式。
