Get complete table with all datasets from Azure Table Storage with v4 Function Apps in C#

With older versions of .NET and Azure Function Apps v2 it was possible to get all datasets from an Azure Table Storage table using (among other things) a TableContinuationToken:
Get more than 1000 datasets from an Azure Table Storage
Since the underlying Microsoft.Azure.Cosmos.Table packages are deprecated:
What is the new, current way in an .NET 6 based v4 Azure Function App to get all datasets from a table in an Azure Table Storage?

I have reproduced the issue in my environment and able to fetch the data list.
Thanks #Gaurav Mantri for the comment.
create a storage account and table in azure.
I used the below code and able to fetch the data list
private void tableInsert()
{
CloudStorageAccount storage_Account = CloudStorageAccount.Parse(storageAccount_connectionString);
CloudTableClient tableClient = storage_Account.CreateCloudTableClient();
CloudTable table = tableClient.GetTableReference("table1");
for (int ctr = 0; ctr < 1000; ctr++)
{
EmployeeEntity employeeEntity = new EmployeeEntity("Fname"+ctr, "LName"+ctr)
{
Email = "something#something.com",
PhoneNumber = "123456789"
};
TableOperation insertOperation = TableOperation.Insert(employeeEntity);
table.ExecuteAsync(insertOperation);
}
}
for fetching
public async Task<List<TableEntity>> GetList()
{
CloudTable table = await GetTableAsync();
TableQuery<TableEntity> query = new TableQuery<TableEntity>();
List<TableEntity> results = new List<TableEntity>();
TableContinuationToken continuationToken = null;
do
{
TableQuerySegment<TableEntity> queryResults = await table.ExecuteQuerySegmentedAsync(query, continuationToken);
continuationToken = queryResults.ContinuationToken;
results.AddRange(queryResults.Results);
} while (continuationToken != null);
return results;
}
private async Task<CloudTable> GetTableAsync()
{
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(storageAccount_connectionString);
CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
CloudTable table = tableClient.GetTableReference("table1");
await table.CreateIfNotExistsAsync();
return table;
}

Microsoft Graph - Filtering in SDK C#

Based on another post, I can filter via HTTP requests as follows:
https://graph.microsoft.com/v1.0/me/events?
$filter=categories/any(a:a+eq+'Red+Category')
I am not sure what the a:a stands for here but it works.
I want to replicate this in Microsoft Graph SDK, I am using a query option as per below which does not return any results:
List<QueryOption> options = new List<QueryOption>
{
new QueryOption("$filter",
"categories/any(a:a+eq+'Red+Category'")
};

You seem to be executing a search instead of a filter in your c# code.
Try using:
var request = graphClient.Users[userId].Events.Request().Filter("categories/any(a:a+eq+'Red+Category')");
var result = await request.GetAsync();
Or alternatively:
List<QueryOption> options = new List<QueryOption>
{
new QueryOption("$filter",
"categories/any(a:a+eq+'Red+Category')")
};

CosmosDB with MongoDB API

Hi I am a newbie on MongoDB and CosmosDB and I try to this in c#
MongoClientSettings settings = MongoClientSettings.FromUrl(
new MongoUrl(connectionString)
);
settings.SslSettings =
new SslSettings() { EnabledSslProtocols = SslProtocols.Tls12 };
var mongoClient = new MongoClient(settings);
var mongoDatabase = mongoClient.GetDatabase("MYDATABASE");
var mongoCollection = mongoDatabase.GetCollection<BsonDocument>("MYCOLLECTION");
var builder = Builders<BsonDocument>.Filter;
var filter = builder.Lt("mac", "001BC50670101BB8") & builder.Gte("date", "2016-09-18T00:00:00Z") & builder.Gte("date", "2017-09-22T00:00:00Z");
var query = mongoCollection.Find<BsonDocument>(filter).ToList<BsonDocument>();
But when it runs the query on the server I get this error:
Errors":["An invalid query has been specified with filters against path(s) that are not range-indexed. Consider adding allow scan header in the request."
I have found that I should add the "x-ms-documentdb-query-enable-scan" header to my request. But how I can do this?

Solution found in comment section:
Query changed from
builder.Lt("mac", "001BC50670101BB8")
to
builder.Eq("mac", "001BC50670101BB8")

mongodb - unable to insert record

I have this code:
public async void SaveAuditLog(AuditLog a)
{
var db = new MongoDBContext();
var o = db.GetMongoDatabase(Common.Common.MongoDbConnectionString);
var audit = o.GetCollection<AuditLog>("AuditLog");
await audit.InsertOneAsync(a);
}
public IMongoDatabase GetMongoDatabase(string connectionstring)
{
MongoClient client = new MongoClient(connectionstring);
return client.GetDatabase("test");
}
this is the connection string from web.config:
<add connectionString="mongodb://localhost:27017" name="mongodb"></add>
when I check the data through robomongo, it does not show me any data inserted.
I have tried the following code as well and no data is inserted:
public async void SaveAuditLog(AuditLog a)
{
var client = new MongoClient(Common.Common.MongoDbConnectionString);
var o = client.GetDatabase("test");
var audit = o.GetCollection<BsonDocument>("AuditLog");
var document = new BsonDocument { {"Test", "test"} };
await audit.InsertOneAsync(document);
}
I am using csharpdriver for mongo with 2.2. What am I doing wrong?

found out that the data is getting inserted in mongodb and there is a bug in robomongo version 0.8.5 itself which does not show collections/documents for mongodb version 3 and above.
ran some scripts (in robomongo) which do return the data:
db.stats()
db.CollectionName.find()
downloaded mongochef and it displayed the data straight away.

Connect CouchDB with asp.net C# application

How to connect couchDB with ASP.NET C# application? If any one can you give a sample application.

I had the same need and after evaluating the options available, to meet the requirements of my application, I created any components that helped me a lot and maybe they can help you and also others. I make it clear that I have no intention of promoting myself here, just sharing something that may be useful.
The detailed explanation of how to configure and use it is on Github.

Example of use for retrieving documents with mango-querie:
IList<User> users;
var sts = new List<String> { "ACTIVE", "LOCKED" };
using (UserRepository db = new UserRepository())
{
var query = db.FindOf("list-status", new { id = "OwnerIdloop.user.7", statuses = sts });
users = db.List<User>(query);
}
Array.ForEach(users.ToArray(), Console.WriteLine);
Example of adding documents:
User user = createUser("email#email.com");
using (UserRepository db = new UserRepository())
{
var result = db.Insert<User>(user); // add document and return instance changed with operation revision id
Console.WriteLine(result.Revision);
}
Example of changing documents:
using (UserRepository db = new UserRepository())
{
// Load document data by ID
var user = db.Get<User>("email#email.com");
user.Name = user.Name + "::CHANGED";
var result = db.Update<User>(user); // update document and return instance changed with operation revision id
Console.WriteLine(result.Revision);
}
Example of deleting documents:
using (UserRepository db = new UserRepository())
{
// Load document data by ID
var user = db.Get<User>("email#email.com");
var result = db.Delete<User>(user); // delete document from database. Return true case sucess or false case not deleted
Console.WriteLine($"Sucesso: {result}");
}

After installing the NuGet, just create an instance of MyCouch.Client and pass it the URL of your database.
using (var client = new MyCouchClient("http://127.0.0.1:5984/test"))
{
//Consume here
}
The format is: {scheme}://[{username}:{password}]/{authority}/{localpath}. From v0.11.0, there's a specific MyCouchUriBuilder that you can use for building the Uri. It will automatically e.g. apply Uri.EscapeDataString to username and password when calling SetBasicCredentials.
var uriBuilder = new MyCouchUriBuilder("http://localhost:5984/")
.SetDbName(TestConstants.TestDbName)
.SetBasicCredentials("foob#r", "p#ssword");
return new MyCouchClient(uriBuilder.Build());
