How do I upload file to Azure function while publishing the code from Visual Studio?

Question

I have created a Azure Function, which is having a dependency on ini file.

 public class DataProcessingFunction
 {
    FunctionName("DataProcessingFunction")]
    public async Task Run([EventGridTrigger]EventGridEvent eventGridEvent,ILogger log)
    {
        string iniFolderPath = $@"{Directory.GetCurrentDirectory()}\Ini\";
        string iniFileName = "Sample.ini";
        var iniConfig = FileManager.ReadFile(iniFolderPath, iniFileName);
    }
 }

I have selected Copy if never option in Visual Studio while publishing the code to Azure function Also, I have tried selecting Embedded Resource. But I am not able to find the file

I get an exception

File not found.

Add/Upload option in Azure portal is disabled because I am publishing the function from Visual studio

Question: Do I need to upload file to blob and then refer it in a code?

Answer 1

Here is the way to do it.

ExecutionContext context; // You can modify your function method to take an additional parameter of type ExecutionContext

public static async Task Run(<.... Other parameters>, ILogger log, ExecutionContext context)

Then build the path by combining function directory, "templates" is the directory I have in the function app project which is deployed along with other code, emails.html is file within templates (For each of these files you have to set, copy-always or copy-if-newer in the properties.). Instead of templates you can have your .ini file.

string templatePath = Path.Combine(context.FunctionAppDirectory, "Templates", "emails.html");
