Azure Web App Temp file cleaning responsibility

Question

In one of my Azure Web App Web API application, I am creating temp files using this code in a Get method

    string path = Path.GetTempFileName();
    // d         


        

Answer 1

Following sample demonstrate how to save temp file in azure, both Path and Bolb.

Doc is here:https://code.msdn.microsoft.com/How-to-store-temp-files-in-d33bbb10
Code click here:https://github.com/Azure-Samples/storage-blob-dotnet-store-temp-files/archive/master.zip

Under part is the core logic of bolb code:

private long TotalLimitSizeOfTempFiles = 100 * 1024 * 1024;

private async Task SaveTempFile(string fileName, long contentLenght, Stream inputStream)
{
    try
    {
        await container.CreateIfNotExistsAsync();

        CloudBlockBlob tempFileBlob = container.GetBlockBlobReference(fileName);

        tempFileBlob.DeleteIfExists();

        await CleanStorageIfReachLimit(contentLenght);

        tempFileBlob.UploadFromStream(inputStream);
    }
    catch (Exception ex)
    {
        if (ex.InnerException != null)
        {
            throw ex.InnerException;
        }
        else
        {
            throw ex;
        }
    }
}

private async Task CleanStorageIfReachLimit(long newFileLength)
{
    List blobs = container.ListBlobs()
        .OfType()
        .OrderBy(m => m.Properties.LastModified)
        .ToList();

    long totalSize = blobs.Sum(m => m.Properties.Length);

    long realLimetSize = TotalLimitSizeOfTempFiles - newFileLength;

    foreach (CloudBlob item in blobs)
    {
        if (totalSize <= realLimetSize)
        {
            break;
        }

        await item.DeleteIfExistsAsync();
        totalSize -= item.Properties.Length;
    }
}
