-The OCR service can read visible text in an image and convert it to a character stream. For more information on text recognition, see the [Optical character recognition (OCR)](../../overview-ocr.md) overview. The code in this section uses the latest [Computer Vision SDK release for Read 3.0](https://www.nuget.org/packages/Microsoft.Azure.CognitiveServices.Vision.ComputerVision/) and defines a method, `BatchReadFileUrl`, which uses the client object to detect and extract text in the image.

+As an optional step, to specify a model version, see [How to specify the model version](../../Vision-API-How-to-Topics/call-read-api.md#determine-how-to-process-the-data-optional). The most recent model includes any enhancements to the previous GA and preview models. For example, to use the model-version=`2022-01-30-preview` parameter, edit the ReadAsync call as shown:
+
+```csharp
+  // Read text from URL with a specific model version
+  var textHeaders = await client.ReadAsync(urlFile,null,null,"2021-09-30-preview");
+```

 ### Get Read results
 
 Next, get the operation ID returned from the **ReadAsync** call, and use it to query the service for operation results. The following code checks the operation until the results are returned. It then prints the extracted text data to the console.
