Consuming Sharepoint web services

asp.netsharepointweb services

How can I consume Sharepoint web services so that I can be able to use Sharepoint document library in the stand alone asp.net application. I have added the web reference to http://<server-url>/_vti_bin/lists.asmx

The SharePoint web services documentation on MSDN contains several how-tos and walkthroughs. The most important ones from what you've described are:

Lists: Retrieving and updating file metadata, checking in and checking out files. Particularly look at UpdateListItems.
List Data Retrieval: Query method returns the items in a list. Use a tool such as U2U CAML Query Builder the create the CAML query.

If you have trouble finding out how to do something, search this site. Many questions about using the SharePoint web services have already been asked here, e.g. this one for uploading documents.

Be warned: relying solely on these web services will probably cause you problems at some point. They are missing a lot of functionality present in the SharePoint user interface and object model. Make sure you test all functionality required with proof of concepts before committing to this approach, or be ready to write a custom web service.

.net – WCF – How toncrease Message Size Quota

You'll want something like this to increase the message size quotas, in the App.config or Web.config file:

<bindings>
    <basicHttpBinding>
        <binding name="basicHttp" allowCookies="true"
                 maxReceivedMessageSize="20000000" 
                 maxBufferSize="20000000"
                 maxBufferPoolSize="20000000">
            <readerQuotas maxDepth="32" 
                 maxArrayLength="200000000"
                 maxStringContentLength="200000000"/>
        </binding>
    </basicHttpBinding>
</bindings>

And use the binding name in your endpoint configuration e.g.

...
bindingConfiguration="basicHttp"
...

The justification for the values is simple, they are sufficiently large to accommodate most messages. You can tune that number to fit your needs. The low default value is basically there to prevent DOS type attacks. Making it 20000000 would allow for a distributed DOS attack to be effective, the default size of 64k would require a very large number of clients to overpower most servers these days.

.net – How to get the webapp’s base URL in ASP.NET MVC

Assuming you have a Request object available, you can use:

string.Format("{0}://{1}{2}", Request.Url.Scheme, Request.Url.Authority, Url.Content("~"));

If it's not available, you can get to it via the context:

var request = HttpContext.Current.Request
