Embedded Lab cannot convert from string to system.guid

Binway — Mon, 22 Aug 2022 08:24:17 GMT

I am following some lab content I found that demonstrates how to embed Power BI content into a web app. The PDfs are fairly straightforward but when I go to debug the code I get an error in the PBIEmbeddedManager.cs file that says "cannot convert from string to system.guid."

It is in relation to this line in the public class PbiEmbeddedManager:

private static readonly string workspaceId = ConfigurationManager.AppSettings["app-workspace-id"];

The code is picking the id up from the Web.config file which has the workspaceid from the url as instructed in the notes. Unfortunately I have no idea how to alter the variable to a GUID or where to put it in the code. It seems I need to add another class?? but I am not certain.

Thanks in advance.

Got it working.

Had to add a bit of extra to the code supplied in git to some classes as per below:

/* renamed the variable to indicate it is a string for workspaceId and reportId*/ private static readonly string strworkspaceId = ConfigurationManager.AppSettings["app-workspace-id"]; private static string datasetId = ConfigurationManager.AppSettings["dataset-id"]; private static readonly string strreportId = ConfigurationManager.AppSettings["report-id"];

Then in this class

public static async Task<ReportEmbeddingData> GetReportEmbeddingData() { PowerBIClient pbiClient = GetPowerBiClient(); /* in this class add the conversion to GUID*/ Guid workspaceId = Guid.Parse(strworkspaceId); Guid reportId = Guid.Parse(strreportId); var report = await pbiClient.Reports.GetReportInGroupAsync(workspaceId, reportId); var embedUrl = report.EmbedUrl; var reportName = report.Name;

But in here it has to go back to string in the GUID("D") format

return new ReportEmbeddingData { /*in here converted the GUID back to string*/ reportId = reportId.ToString("D"), reportName = reportName,

With the report working.
