Get file names from azure blob storage

I'm using azure blobstorage in c#, is there a way, a method to get the list of files from a given specific folder?
like get all file names inside this url https://prueba.blob.core.windows.net/simem/UAL/Dato%20de%20archivo%20prueba%20No1/2022/1/16
i know that using container.GetBlobs() i would get all files but not from a specific folder

Just use
var results = await container.ListBlobsSegmentedAsync(prefix, true, BlobListingDetails.None, null, null, null, null);

You can get file names from a specific folder using BlobServiceClient and GetBlobs and by using below code in C# Console App and I followed Microsoft-Document and #Cindy Pau's answer:
using Azure.Storage.Blobs;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp4
{
class Program
{
static void Main(string[] args)
{
string cs= "Connection String of Storage Account";
string f = "test";
BlobServiceClient b = new BlobServiceClient(cs);
string c = "pool";
BlobContainerClient containerClient =b.GetBlobContainerClient(c);
var bs= containerClient.GetBlobs(prefix: f);
foreach (var x in bs)
{
Console.WriteLine(x.Name);
Console.ReadLine();
}
}
}
}
In Storage Account of pool Container:
Now inside test Folder:
Output:
Press Enter after every line to get File names one by one.

How to use PutAsJsonAsync in .NET 4.72?

I am planning to use HTTP PUT in a WPF .NET 4.7.2 application and before I get started I wanted to quickly test putting data using a console .NET 4.7.2 application but I am getting an error on var response = client.PutAsJsonAsync("api/person", p).Result;
Error:
Error CS1061 'HttpClient' does not contain a definition for 'PutAsJsonAsync' and no accessible extension method 'PutAsJsonAsync' accepting a first argument of type 'HttpClient' could be found (are you missing a using directive or an assembly reference?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using ClassLibrary;
using System.Threading;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Net.Http.Formatting;
namespace HTTP
{
class Program
{
static void Main(string[] args)
{
using (var client = new HttpClient())
{
person p = new person { name = "Sourav", surname = "Kayal" };
client.BaseAddress = new Uri("http://localhost:1565/");
var response = client.PutAsJsonAsync("api/person", p).Result;
if (response.IsSuccessStatusCode)
{
Console.Write("Success");
}
else
Console.Write("Error");
}
Console.ReadKey();
}
}
}

You can install the Newtonsoft.Json NuGet package and use it this way instead :
using Newtonsoft.Json;
using System;
using System.Net.Http;
using System.Text;
using (HttpClient client = new HttpClient())
{
Person p = new Person { name = "Sourav", surname = "Kayal" };
string jsonObject = JsonSerializer.Serialize(p);
var content = new StringContent(jsonObject, Encoding.UTF8, "application/json");
client.BaseAddress = new Uri("http://localhost:1565/");
var response = client.PutAsync("api/person", content).Result;
if (response.IsSuccessStatusCode) Console.Write("Success");
else Console.Write("Error");
}
Here is the Microsoft documentation (.NET Framework 4.7.2) :
HttpClient.PutAsync Method
Not sure the System.Net.Http.Json.HttpClientJsonExtensions.PutAsJsonAsync method is available for .NET Framework 4.7.2...

C# cannot connect to vmware

I have a project where i will have to build dual stacked virtual machines. I usually work with powershell but it does not appear to be able to do that. I may have to use C#. I am kinda rusty on this but for some reason this code give me an error "Cannot create an instance of the abstract class or interface 'VMware.Vim.VimClient'".
using System.Text;
using VMware.Vim;
namespace Vimfunctions
{
public class VimFunctions
{
protected VimClient ConnectServer(string viServer, string viUser, string viPassword)
{
**VimClient vClient = new VimClient();**
ServiceContent vimServiceContent = new ServiceContent();
UserSession vimSession = new UserSession();
vClient.Connect("https://" + viServer.Trim() + "/sdk");
vimSession = vClient.Login(viUser, viPassword);
vimServiceContent = vClient.ServiceContent;
return vClient;
}
I added the reference to the project. I must have forgot to do something.

As per https://communities.vmware.com/thread/478700:
"either stick with the PowerCLI 5.5 release as mentioned or to modify your code to use the VimClientImpl class instead of VimClient (which is now an interface)."
A complete simple example I used:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using VMware.Vim;
namespace vSphereCli
{
class Program
{
static void Main(string[] args)
{
VMware.Vim.VimClientImpl c = new VimClientImpl();
ServiceContent sc = c.Connect("https://HOSTNAME/sdk");
UserSession us = c.Login("admin#vsphere.local", "password");
IList<VMware.Vim.EntityViewBase> vms = c.FindEntityViews(typeof(VMware.Vim.VirtualMachine), null, null, null);
foreach (VMware.Vim.EntityViewBase tmp in vms)
{
VMware.Vim.VirtualMachine vm = (VMware.Vim.VirtualMachine)tmp;
Console.WriteLine((bool)(vm.Guest.GuestState.Equals("running") ? true : false));
Console.WriteLine(vm.Guest.HostName != null ? (string)vm.Guest.HostName : "");
Console.WriteLine("");
}
Console.ReadLine();
}
}
}
Add a reference to "C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\VMware.Vim.dll". Update the hostname, password; and volia!

Server unable to execute EWS autodiscover

On our testing server, EWS autodiscover does not work. To eliminate an ill-set IIS option from the list of causes, I C&P'ed together a WindowsForms Application (code below) and put it, together with the Microsoft.Exchange.Webservice.dll, into a folder on which I have write permission.
Unfortunately, neither xml nor text file are created. Instead, I get an Unhandled Exception error.
System.NullReferenceException
at System.Windows.Forms.TextBoxBase.AppendText(String text)
This does not happen on my development machine, which is in the same AD domain and on which the test app always returns that autodiscover was successful.
Question: How come no Trace output is generated?
So now, my app code:
Form1.cs
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Microsoft.Exchange.WebServices;
using Microsoft.Exchange.WebServices.Data;
namespace ADDebugWin
{
public partial class Form1 : Form
{
public static string traceData;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
ExchangeService ews = new ExchangeService(ExchangeVersion.Exchange2010);
ews.TraceListener = new TraceListener();
// Optional flags to indicate the requests and responses to trace.
ews.TraceFlags = TraceFlags.EwsRequest | TraceFlags.EwsResponse;
ews.TraceEnabled = true;
ews.UseDefaultCredentials = true;
try {
ews.AutodiscoverUrl("email#mydomain.com");
textBox1.AppendText("AutoDiscover erfolgreich.");
} catch (Exception ex) {
textBox1.AppendText(traceData);
textBox1.AppendText(ex.Message + "\r\n" + ex.StackTrace);
}
}
}
}
TraceListener.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using ADDebugMvc.Controllers;
using Microsoft.Exchange.WebServices.Data;
using System.Xml;
namespace ADDebugMvc.Models
{
class TraceListener : ITraceListener
{
public void Trace(string traceType, string traceMessage)
{
CreateXMLTextFile(traceType, traceMessage.ToString());
HomeController.traceData += traceType + " " + traceMessage.ToString() + "\r\n";
}
private void CreateXMLTextFile(string fileName, string traceContent)
{
// Create a new XML file for the trace information.
try
{
// If the trace data is valid XML, create an XmlDocument object and save.
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load(traceContent);
xmlDoc.Save(fileName + ".xml");
}
catch
{
// If the trace data is not valid XML, save it as a text document.
System.IO.File.WriteAllText(fileName + ".txt", traceContent);
}
}
}
}

One should note that
ews.TraceFlags = TraceFlags.EwsRequest | TraceFlags.EwsResponse;
is not returning any Traces during AutoDiscover.
(ews.TraceFlags = TraceFlags.All; does.)
So no string is appended to traceData, which is why traceData==null -> Exception when appending it to a TextBox.

eBay Finding API .NET SDK 'findItemsAdvanced' returns null response

I'm trying to use the eBay Finding API to send an advanced search request and return the results. I have included my code below.
For some reason when I get to the following line:
FindItemsAdvancedResponse response = service.findItemsAdvanced(request);
the object called "response" is coming back as null.
I'm not sure where I'm going wrong and no exception is being thrown from the call to service.findItemsAdvanced()
If you could take a look and offer any advice at all I would be most grateful.
Here is my program.cs up until the problem
Progam.cs
using System;
using System.ServiceModel;
using System.ServiceModel.Channels;
using EbayParser.com.ebay.developer;
using System.Net;
namespace EbayParser
{
class Program
{
static void Main(string[] args)
{
try
{
// Creating an object to the BestMatchService class
CustomFindingService service = new CustomFindingService();
service.Url = "http://svcs.sandbox.ebay.com/services/search/FindingService/v1";
com.ebay.developer.FindItemsAdvancedRequest request = new EbayParser.com.ebay.developer.FindItemsAdvancedRequest();
//Create Filter Objects
com.ebay.developer.ItemFilter filterEndTimeFrom = new EbayParser.com.ebay.developer.ItemFilter();
com.ebay.developer.ItemFilter filterEndTimeTo = new EbayParser.com.ebay.developer.ItemFilter();
com.ebay.developer.ItemFilter filterCatID = new EbayParser.com.ebay.developer.ItemFilter();
//Set Values for each filter
filterEndTimeFrom.name = EbayParser.com.ebay.developer.ItemFilterType.EndTimeFrom;
filterEndTimeFrom.value = new string[] { "" };
filterEndTimeTo.name = EbayParser.com.ebay.developer.ItemFilterType.EndTimeTo;
filterEndTimeTo.value = new string[] { "" };
filterCatID.name = EbayParser.com.ebay.developer.ItemFilterType.EndTimeFrom;
filterCatID.value = new string[] { "" };
//Create the filter array
com.ebay.developer.ItemFilter[] itemFilters = new EbayParser.com.ebay.developer.ItemFilter[3];
//Add Filters to the array
itemFilters[0] = filterCatID;
itemFilters[1] = filterEndTimeFrom;
itemFilters[2] = filterEndTimeTo;
request.itemFilter = itemFilters;
request.keywords = "ipod";
// Creating response object
FindItemsAdvancedResponse response = service.findItemsAdvanced(request);
and here is the code for the class called "CustomFindingService.cs"
CustomFindingService.cs
using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using EbayParser.com.ebay.developer;
namespace EbayParser
{
class CustomFindingService : FindingService
{
protected override System.Net.WebRequest GetWebRequest(Uri uri)
{
try
{
HttpWebRequest request = (HttpWebRequest)base.GetWebRequest(uri);
request.Headers.Add("X-EBAY-SOA-SECURITY-APPNAME", "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx");
request.Headers.Add("X-EBAY-SOA-OPERATION-NAME", "findItemsByKeywords");
request.Headers.Add("X-EBAY-SOA-SERVICE-NAME", "FindingService");
request.Headers.Add("X-EBAY-SOA-MESSAGE-PROTOCOL", "SOAP11");
request.Headers.Add("X-EBAY-SOA-SERVICE-VERSION", "1.0.0");
request.Headers.Add("X-EBAY-SOA-GLOBAL-ID", "EBAY-US");
return request;
}
catch (Exception ex)
{
throw ex;
}
}
}
}

I had exactly the same problem when I went from finding by keywords to using the advanced method. I spent a while scratching my head myself but it turned out to have a simple fix:
Your header X-EBAY-SOA-OPERATION-NAME reads findItemsByKeywords. Changing it to findItemsAdvanced should do the trick.

If you leave any of the filters blank in the filter array you will get the SOA Operation Header missing exception whether or not you have included the headers correctly.
You should check the filters are not null before applying them to your request.
