C# program to call existing web API - c#

How can I call / use web API that supports SOAP and REST? I want to write a program in C# that will use this web API. I didn't get much information on the internet. So far, I have created C# project and added the web service reference (WSDL) to my program. Now how can I use the web API. How to send request or receive response? Can you please refer me some good tutorials ?

The HttpClient class is a good starting point. Also there is the EasyHttp library.
Code sample HttpClient: http://code.msdn.microsoft.com/Introduction-to-HttpClient-4a2d9cee

Adding web service reference creates client classes that can be used to communicate with web service. All created classes will be in new namespace, You have to look for client proxy class (full name depends on WebService name). Create instance of this class. Calling its methods will call WebService. Here you can read about using Web Services in C#

The easiest way I know to consume a SOAP API is to create a C# project and add a service reference.
Then add the address of your website and Visual Studio will generate a proxy for your WebService.
You will be able to call it in your project (Website/ConsoleApp).
You can have a sample of how to call the client when you call the svc of your WebSite if you use WCF.
ex: http://<host>[/route]/<name of svc>.svc

TFS Extension Data Service C#

Does the TFS Extension Data web service have a similar service in C#? I am trying to get custom TFS extension data through C# instead of REST API.
I assume you want to use C# instead of JavaScript, as REST API (httprequest) can be called in any language.
There are two ways to interact with the data storage service: REST APIs or a Microsoft-provided client service available as part of the VSS SDK. Please check the rest api in the following link, and call this api in your code:
https://learn.microsoft.com/en-us/vsts/extend/develop/data-storage#advanced
The getValue method is a wrapper around the REST APIs, issuing a GET request to the following endpoint:
GET _apis/ExtensionManagement/InstalledExtensions/{publisherName}/{extensionName}/Data/Scopes/User/Me/Collections/%24settings/Documents/myKey

SOAP WebService... How?

I have a sharepoint web service running at specified host + "/_vti_bin/UserProfileWebService.asmx". I would like to instantiate a web service client, so that i could interact with this service. This is basically what I am trying to do: http://msdn.microsoft.com/en-us/library/ms550407.aspx.
How is this done in .NET? And do I have to use the MOSS API to know what functions it supports?
EDIT:
I guess I should add that I want to connect programmatically, not through a web reference, because that seems to be static.
In VS (2008/2010) you can add a web service reference to your console project for example. It will auto-generate the proxy classes for you to use in your code.

Calling basic authentication java webservice with C# Client

I have a c# client application calling java web services. Everything works great but now i need to send some authentication data since we are trying to restrict who calls the web service. The java web service expects basic authentication.
How do i go about providing this in my c# client? I am not using WCF or WSE, just plain webservice (using Add Web Reference).
Here's a link for the solution i found in case some one needs it. I was able to fix my issue by modifying some of the stuff in the suggested article.

Call WebService using HTTPWebRequest object

i want to consuming a web service with HTTPWebRequest object the web service may be written using java.(doon't want to consume adding web reference)
Marcin provides a sample in his blog: Link .
Though it's consuming a .net based web service, but it doesn't make difference from the consumer's point of view.
The basic idea is you need to compose a soap request message and send it to server properly.
