Error while reading files from Directory with IConfiguration

I am trying to read dll's from a directory like this :
public static class CommonMethod
{
/// <summary>
/// Load dll files and read the assmbely
/// </summary>
/// <param name="a_mConfig"></param>
/// <returns>instence list of plugin</returns>
/// <exception cref="OHException"></exception>
public static List<IMessageGenerator/*INotificationSender*/> ReadAssemblies(IConfiguration a_mConfig)
{
var pluginsLists = new List<IMessageGenerator/*INotificationSender*/>();
try
{
//Read the dll files from the folder
var files = Directory.GetFiles(a_mConfig.GetSection("AppSettings:PluginFilesPath").ToString(), a_mConfig.GetSection("AppSettings:PluginFilesFormat").ToString());
if (files == null)
throw new OHException(ExceptionMessage.FILE_NOT_FOUND);
//Read the assembly from files
foreach (var file in files)
{
var d = Path.Combine(Directory.GetCurrentDirectory(), file);
var assembly = Assembly.LoadFile(Path.Combine(Directory.GetCurrentDirectory(), file));
//Exteract all the types that implements IPlugin
var pluginTypes = assembly.GetTypes().Where(t => typeof(IMessageGenerator/*INotificationSender*/).IsAssignableFrom(t) && !t.IsInterface).ToArray();
foreach (var pluginType in pluginTypes)
{
//Create an instance from the extracted type
//var pluginInstance = Activator.CreateInstance(pluginType) as IMessageGenerator;
var pluginInstance=Activator.CreateInstance(pluginType,a_mConfig) as IMessageGenerator/*INotificationSender*/;
pluginsLists.Add(pluginInstance);
}
}
}
catch (Exception ex)
{
throw new OHException($"{ExceptionMessage.UNABLE_TO_READ_DLL} because : {ex.Message}");
}
return pluginsLists;
}
.
.
.
But this error is being thrown:
Unable to read the plugin dll file because :Could not find a part of the path 'E:\dir\Project-Name\Project.QueueDataProcessor\Microsoft.Extensions.Configuration.ConfigurationSection'.=> at Project.QueueDataProcessor.CommonMethods.CommonMethod.ReadAssemblies(IConfiguration a_mConfig) in E:\dir\Project-Name\Project.QueueDataProcessor\CommonMethods\CommonMethod.cs:line 57
at Project.QueueDataProcessor.Services.ProcessQueueData.SendQueueDataToPlugin() in E:\dir\Project-Name\Project.QueueDataProcessor\Services\ProcessQueueData.cs:line 35
What am I doing wrong? Basically, previously I created a class to read appsettings but now I am trying to replace it with IConfiguration because of dependency issues.

How to get all TeamDrives, Folders, and Files with Google Drive API (using pagination)

I have to go through all team drives, folders, and files and the code I have works perfectly fine:

}
catch (Exception ex)

}
}
The problem is that I cant set PageSize to something above 100.
How can I change this code to actually to go through everything?

Assuming that you are using drives list and files list. Which is just a guess since you haven't included the code GetAllTeamDrivesAsync? GetAllFoldersFromTeamDriveAsync.
You can set the page size to max 1000 on your file.list method.
var request = service.Files.List();
request.PageSize = 1000;
But thats you are still going to need to paginate over the page. I recommend using the pageStreamer. It will loop over each of the rows for you.
var request = service.Files.List();
request.PageSize = 1000;
var pageStreamer =
new Google.Apis.Requests.PageStreamer<Google.Apis.Drive.v3.Data.File, FilesResource.ListRequest,
Google.Apis.Drive.v3.Data.FileList, string>(
(req, token) => request.PageToken = token,
response => response.NextPageToken,
response => response.Files);
// data storage
var all = new Google.Apis.Drive.v3.Data.FileList();
all.Files = new List<Google.Apis.Drive.v3.Data.File>();
// fetching data and adding it to storage
foreach (var result in await pageStreamer.FetchAllAsync(request, CancellationToken.None))
{
all.Files.Add(result);
}
I have a video up that explains how pagestreamer works How to use the nextpagetoken from the files list method in the Google Drive api v3.
You should be able to use pagestreamer with drives list as well.

Logging all unhandled exception under hosted environment

I knew that I am re-inventing the wheel. But still, I have to do it as I am instructed to do so :D.
I have to log all unhandled exception of my asp.net website. I am able to dynamically catch all exceptions but I am not able to retrieve the actual class and method name.
Everytime I got Global_asax as class name and Application_Error as the method name. Below is my code.
/// <summary>
/// Determines the log type and saves log to database. Use logtype 1 for exception logging
/// and 2 for normal audit trail.

if (declaringType != null)
{
appLog.ClassName = declaringType.FullName;
appLog.MethodName = ex.TargetSite.Name;
}
appLog.LogDetails = ex.ToString();
appLog.Message = ex.Message;
}
else
{
appLog.ClassName = stackFrame.GetMethod().DeclaringType.AssemblyQualifiedName;
appLog.MethodName = memberName;
appLog.LogDetails = obj.ToString();
appLog.Message = "User defined custom exception";
}
}
else
{
appLog.LogType = 2;
appLog.ClassName = stackFrame.GetMethod().DeclaringType.AssemblyQualifiedName;
appLog.MethodName = memberName;

appLog.Message = "User defined custom exception";
}
}

appLog.MethodName = ex.TargetSite.Name;
}
finally
{
HttpWebMethods.PostAsync(ConfigurationSettingsHelper.LoggerApiBaseAddress,
ConfigurationSettingsHelper.SaveLogEndpoint, appLog);
} // intentionally eating exception}
}
finally
{
HttpWebMethods.PostAsync(ConfigurationSettingsHelper.LoggerApiBaseAddress,
ConfigurationSettingsHelper.SaveLogEndpoint, appLog);
}
}
It's logging all good at all places. But for the case of any unhandled exceptions, I need to capture the class name and method name. But instead, its giving me the global.asax details.
Its a class library and i want it work as same as Global.asax works. Automatically recognizes all errors.
Please help.

install transport Agent (Exchange) programmatically

Is it possible to install a Transport Agent to Exchange Server within a C# programm?
Normally you create your Agent .dll, then you need to open Exchange Management Shell and execute the following commands:
Install-TransportAgent -Name "Agent Name" -TransportAgentFactory "Factory.Class.Name" -AssemblyPath "C:\Path\to\agent.dll"
and
enable-transportagent -Identity "Agent Name"
and setting the priority:
Set-TransportAgent -Identity "Agent Name" -Priority 3
How can I install the transport agent from within a C# application (either calling a PowerShell command or directly using the .NET Framework?

I found a solution using PowerShell directly from C# and calling the corresponding cmdlets:

Yes, Its possible to install\uninstall Exchange Transport agent using C#. In fact, i have done it.
What i did is, I called exchange cmdlets using PowerShell, and installed the agent on exchange hub server. I also had to stop\start MS Exchange Transport Agent service using C#. Besides, i also had to create the folder, where i had to place agent files, and also grant Network Service read\write permission on that folder.
Regards,
Laeeq Qazi

I have written a class which allows you to run exchange commands either locally or through a remote shell.
The following commands are available in this class:
GetAgentInfo : Receive the transport agent information by passing the NAme as parameter
InstallAgent : Install a transport agent by passing Name, FactoryNAme and Assembly path
EnableAgent : Enable a transport agent
UninstallAgent : Uninstall a transportagent
RestartTransportService : Restart the Microsoft Transport Service
It also verifies what version of Exchange is installed to load the correct SnapIn
Here is the code writte in C#:

Retrieve Access Information Google gdata-api C#

I am attempting to retrieve the most recent date that my users have logged into any Google app service such as Gmail (or had this done for them via mobile device/imap/pop etc). I am an administrator of the domain on Google apps for Education and using the C# gdata-api.
I would like to recycle student usernames if they have been gone for longer than a year without signing into their gmail apps and require the last accessed date to accomplish this.
Please let me know if this is possible
Thank you.

I used the gmail reporting API. I forget where I got this from but I stole it from somewhere. If you know where, please put a comment link.
