C# PowerBI API |导入PBIX
我有一种方法可以将.PBIX文件上载到我的PowerBI应用程序，该方法会按预期返回一个id。但是，报告和数据集不会出现在PowerBI上 我的方法：C# PowerBI API |导入PBIX,c#,powerbi,C#,Powerbi,我有一种方法可以将.PBIX文件上载到我的PowerBI应用程序，该方法会按预期返回一个id。但是，报告和数据集不会出现在PowerBI上 我的方法： public static string SendFile() { string[] files = { "D://David/Documents//PBIX_TEST.pbix" }; string boundary = "-----------------------
