无法确定URI的格式
本文关键字：格式 URI 无法确定 | 更新日期: 2023-09-27 18:13:10
我正在研究从考勤系统中获取考勤记录的应用程序，并将其放在访问文件中并上传到我的网站。它工作成功，但当我专注于其他屏幕在我的桌面，回到应用程序给出这个错误!"无效的URI:无法确定URI的格式"
这是代码:

序言编辑:
结果不是这些愚蠢的东西。实例化Uri需要相应的方案。调用new Uri("example.com/path")将导致此异常。相反，您应该呼叫new Uri("http://example.com/path")。但是，如果这不是您遇到的问题，请继续……
我不知道这个错误在哪里发生，以提供更多的细节，但这意味着你需要在Uri构造函数中指定UriKind。例如，new Uri("/path")可能会抛出一个错误，我指定new Uri("/path", UriKind.Relative)，这样它就可以工作了。所以无论你在哪里确定错误的来源，或者无论你在哪里调用那个构造函数，都要加上它。
我看到你打电话来
Uri url = new Uri(urlAdress);
在一个点。我跟你打赌就是这样。只需在该参数中添加任何类型值urlAddress是指(它来自您的配置文件，但它可能是UriKind.Absolute)，你会是金色的。
