使用.NET Core的Azure存储CRUD操作

Question

I've been working with Azure Storage resources recently, particularly I was just playing around with CRUD operations in Table. I was able to accomplish a task using .NET Framework, however, recently my requirements have changed and I had to migrate to .NET Core. I wrote the same type of code by it reaches try-catch statement in CreateTable() and stop for no reason, I am not getting any exceptions or messages, program just exits from there. I have been trying to figure out this issue, so far I came to the following solution that seems to be missing a tiny piece to make it work.

Moreover, previously I was using CosmosDB API to perform this operations. Unfortunately, it is not available in .NET Core, therefore I came up with this solution.

My thoughts: I am concerned about authentication part as well, since I can't determine if it was successful or not. It goes through Auth() well without problems. I would appreciate if anyone could give me the right direction to the solution of this problem. Thanks!

    static CloudStorageAccount _storageAccount;
    static void Main(string[] args)
    {
        Auth();
        CreateTable();
    }
    static void Auth()
    {
         _storageAccount = new CloudStorageAccount(
             new Microsoft.WindowsAzure.Storage.Auth.StorageCredentials(
                 "MyResource", "MyKey"),true);
    }

    async static void CreateTable()
    {
        CloudTableClient tableClient = _storageAccount.CreateCloudTableClient();
        CloudTable peopleTable = tableClient.GetTableReference("XYZ");
        try
        {
            await peopleTable.CreateIfNotExistsAsync();
        }
        catch(Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        People customer = new People("Garry", "Johnson");
        customer.Email = "xxx@yyy.zzz";
        customer.PhoneNumber = "123456789";
        TableOperation insertOperation = TableOperation.Insert(customer);
        var result = await peopleTable.ExecuteAsync(insertOperation);
    }

}

Answer 1

I wrote the same type of code by it reaches try-catch statement in CreateTable() and stop for no reason.

As the CreateTable() is an async method, the program will exit with no wait to get exectution result.

I would appreciate if anyone could give me the right direction to the solution of this problem

Please have a try to use the following demo code. If get the 204 in the console meanings that create table and insert record to the table successfully, or you will get the exception information in the console.

static void Main(string[] args)
        {
            Auth();
            var result = CreateTable().Result;
            Console.WriteLine(result);
            Console.ReadKey();
        }

async static Task<string> CreateTable()
{
      CloudTableClient tableClient = _storageAccount.CreateCloudTableClient();
      CloudTable peopleTable = tableClient.GetTableReference("XYZ");
      try
         {
                await peopleTable.CreateIfNotExistsAsync();
                People customer = new People("Garry", "Johnson");
                customer.Email = "xxx@yyy.zzz";
                customer.PhoneNumber = "123456789";
                TableOperation insertOperation = TableOperation.Insert(customer);
                var result = await peopleTable.ExecuteAsync(insertOperation);
                return result.HttpStatusCode.ToString();
        }
        catch (Exception ex)
        {
             Console.WriteLine(ex.Message);
        }
        return null;

  }
