How to get a clients computer name in asp net core

Introduction

ASP.NET is a popular used for web . In this article, we will discuss how to get a client's computer name in ASP.NET Core.

Using Request.UserHostName

One way to get the client's computer name is by using the Request.UserHostName property. This property returns the client's IP address or the client's DNS name if it is available.


string clientComputerName = Request.UserHostName;

The clientComputerName variable will now contain the client's computer name.

Using Dns.GetHostEntry

If the Request.UserHostName property does not the desired , we can use the Dns.GetHostEntry method to get the client's computer name.


string clientIPAddress = Request.UserHostAddress;
string clientComputerName = Dns.GetHostEntry(clientIPAddress).HostName;

In this example, we first obtain the client's IP address using the Request.UserHostAddress property. Then, we pass this IP address to the Dns.GetHostEntry method to retrieve the client's computer name.

Handling Exceptions

It is important to handle exceptions when retrieving the client's computer name, as it may not always be available or accessible. For example, if the client is behind a proxy server, the computer name may not be retrievable.


try
{
    string clientComputerName = Request.UserHostName;
    // or
    string clientIPAddress = Request.UserHostAddress;
    string clientComputerName = Dns.GetHostEntry(clientIPAddress).HostName;
}
catch (Exception ex)
{
    // Handle the exception
    Console.WriteLine("Error retrieving client computer name: " + ex.);
}

By wrapping the code in a try-catch block, we can gracefully handle any exceptions that may occur during the retrieval of the client's computer name.
