(C# UWP/WinRT) SharePoint -- Delete a File

Demonstrates how to delete a SharePoint file.

Chilkat Universal Windows Platform (UWP) / WinRT Downloads

Chilkat for the Universal Windows Platform (UWP)

//  This requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();

//  If SharePoint Windows classic authentication is used, then set the
//  Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = "SHAREPOINT_USERNAME";
http.Password = "SHAREPOINT_PASSWORD";
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN";
http.NtlmAuth = true;

//  The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
//  If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
//  establish the cookie as shown at SharePoint Online Authentication

//  This example will delete the file named "penguins2.jpg"
//  which is located in the "/Documents" folder.

Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.HttpVerb = "POST";
req.Path = "/_api/web/GetFileByServerRelativeUrl('/Documents/penguins2.jpg')";

//  We need to add a form digest value in the X-RequestDigest header field.
//  See this example for details on
//  how to get (and cache) a form digest value
req.AddHeader("X-RequestDigest","SHAREPOINT_FORM_DIGEST");

//  Add additional required headers.
req.AddHeader("IF-MATCH","*");
req.AddHeader("X-HTTP-Method","DELETE");

//  Send the POST using https (TLS). Port 443 is the default port for https.
bool bUseTls = true;
Chilkat.HttpResponse resp = await http.SynchronousRequestAsync("SHAREPOINT_HTTPS_DOMAIN",443,bUseTls,req);
if (http.LastMethodSuccess != true) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

//  If failed, the response body contains XML
Chilkat.Xml xml = new Chilkat.Xml();
xml.LoadXml(resp.BodyStr);

if (resp.StatusCode != 200) {
    Debug.WriteLine("Response status code = " + Convert.ToString(resp.StatusCode));
    Debug.WriteLine(xml.GetXml());

    //  For example, if the file did not exist, this would be the XML response:
    //  <?xml version="1.0" encoding="utf-8" ?>
    //  <m:error xmlns:m="http://schemas.microsoft.com/ado/2007/08/dataservices/metadata">
    //      <m:code>-2146232832, Microsoft.SharePoint.SPException</m:code>
    //      <m:message xml:lang="en-US">The file /Documents/penguins2.jpg does not exist.</m:message>
    //  </m:error>
    // 

    Debug.WriteLine("Failed");

    return;
}

//  If successful, the response body is empty.
Debug.WriteLine("Success.");
