Azure Function Blob Trigger CloudBlockBlob binding

Question

I have the following Azure function triggered when a file is uploaded to Blob Storage

[FunctionName("ImageAnalysis")]
    public static async void Run(
        [BlobTrigger("imageanalysis/{name}", Connection = "AzureWebJobsStorage")] Stream myBlob, 
        string name, 
        TraceWriter log)
    {
        log.Info($"C# Blob trigger function Processed blob\n Name:{name} \n Size: {myBlob.Length} Bytes");
    }

I want to process the Blob that has been uploaded so ideally I would like it as a CloudBlockBlob instead of a Stream. Then I can just do some work and then delete the blob.

myBlob.DeleteIfExists()

是否有一种简单的方法可以将Stream转换或转换为CloudBlockBlob，还是需要使用输入/输出绑定或其他方法？

查看文档，我看到了使用CloudBlockBlob的示例，但似乎无法正常运行，因此认为我缺少了什么？

使用此语法进行绑定。技巧是FileAccess.ReadWrite在属性中指定。出于某种原因，这些文档相当混乱地将其称为“ inout”。

[Blob("imageanalysis/{name}", FileAccess.ReadWrite, Connection = "AzureWebJobsStorage")] CloudBlockBlob blob, string name
