Unable to open OST file in C# [.net]

I’m working as a Junior Application Developer in MNC. I’m trying to develop an application where I have to open OST file in C# programming. I’m using C# 7.0 version in Visual Studio 2017. In the latest version, I can easily use local functions while developing an application. While writing code I’m facing errors in code. The following code I’ve used:

try

{

mail = OutlookApp.CreateItem(Outlook.OlItemType.olMailItem)

as Outlook.MailItem;

mail.Subject = “A programatically generated e-mail”;

mailRecipients = mail.Recipients;

mailRecipient = mailRecipients.Add(“Eugene Astafiev”);

mailRecipient.Resolve();

if (mailRecipient.Resolved)

{

mail.Send();

}

else

{

System.Windows.Forms.MessageBox.Show(

“There is no such record in your address book.”);

}

}

catch (Exception ex)

{

System.Windows.Forms.MessageBox.Show(ex.Message,

“An exception is occured in the code of add-in.”);

}


 

After searching a lot about this error on this forum. I have found one topic related to OST.

I can’t get a solution on above thread. Then I searched on other forums and found few references. Please refer these references and provide your suggestion.

First question: What errors are you actually seeing when trying that code?
Second up: Are you trying to reimplement this in PowerShell? If not, you may find more luck posting on a more C# heavy forum, or on Stack Overflow (or one of their subsites). You may notice that you’ve posted this in the “General PowerShell Q&A”, which doesn’t really seem to cover this question.
