Error when trying to add an Azure Blob Storage URI to an Azure Storage Table

Question

I'm trying to add images to Azure blob storage, (this part of the program works correctly).

Once each image is in the blob storage I want to create an Azure storage table with an entity having two columns. The image category, and the image URI.

When I try to insert into the Azure Storage Table the application enters "break mode".

Ultimately this will be used by a mobile app that uses the table to select image URIs as the imagesource for a grid view so I need the full URI.

I've hardcoded the category to try and narrow down the problem.

I'm using the Azure Storage Emulator during development. FYI.

using Microsoft.WindowsAzure.Storage;
using Microsoft.WindowsAzure.Storage.Blob;
using Microsoft.WindowsAzure.Storage.Queue;
using Microsoft.WindowsAzure.Storage.Table;

namespace AzureEmulatorTests
{
    class Program
    {
        static async Task Main(string[] args)
        {
            const string localPath = "./data/";
            const string containerName = "mycontainer";
            const string tableName = "mytable";

            var storageAccount = CloudStorageAccount.Parse(@"UseDevelopmentStorage=true");

            var blobClient = storageAccount.CreateCloudBlobClient();
            var container = blobClient.GetContainerReference(containerName);
            await container.CreateIfNotExistsAsync();

            var tableClient = storageAccount.CreateCloudTableClient();
            var table = tableClient.GetTableReference(tableName);
            await table.CreateIfNotExistsAsync();

            string[] filenames = Directory.GetFiles(localPath);

            foreach (var images in filenames)
            {
                string _imageBlobReference = Guid.NewGuid() + ".jpg";

                var blob = container.GetBlockBlobReference(_imageBlobReference);
                await blob.UploadFromFileAsync(images);
                string blobUrl = blob.Uri.AbsoluteUri;

                ImageFile image = new ImageFile("Birthday", blobUrl);

                await table.ExecuteAsync(TableOperation.Insert(image));
            }

            Console.WriteLine("Files Uploaded... Press any key to continue.");
            Console.ReadKey();
        }
    }

    class ImageFile : TableEntity
    {
        public ImageFile(string Category, string ImageURL)
        {
            PartitionKey = Category;
            RowKey = ImageURL;
        }
    }
}

Answer 1

The solution I found is to not put the URL in the PartitionKey or Rowkey properties.

When I added a string property to the table, I was able to add the URL without issue.
