Question
You are developing a method that uses the Azure AI Vision client library. The method will perform optical character recognition (OCR) in images. The method has the following code. During testing, you discover that the call to the GetReadResultAsync method occurs before the read operation is complete. You need to prevent the GetReadResultAsync method from proceeding until the read operation is complete. Which two actions should you perform? Each correct answer presents part of the solution. (Choose two.) NOTE: Each correct selection is worth one point.
Options
- ARemove the Guid.Parse(operationId) parameter.
- BAdd code to verify the results.Status value.
- CAdd code to verify the status of the txtHeaders.Status value.
- DWrap the call to GetReadResultAsync within a loop that contains a delay.
Explanation
