(C#) SharePoint -- Check In a File

In SharePoint, you can check out a file to make sure nobody can change it before you update it. After updating, you can check in the file. This example shows how to check in a SharePoint file.

Chilkat .NET Downloads Chilkat .NET Framework Chilkat for .NET Core

// 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 check in the file named "penguins2.jpg" 
// which is located in the "/Documents" folder.

Chilkat.HttpRequest req = new Chilkat.HttpRequest();
req.HttpVerb = "POST";
// Note that our path uses GetFileByServerRelativeUrl and not GetFolderByServerRelativeUrl
// Also, if your Sharepoint site is within a site collection, the URL is formatted like this (where "teamA" is the name of the site)
// /sites/teamA/_api/web/GetFileByServerRelativeUrl('/sites/teamA/Documents/penguins2.jpg')/CheckIn(comment='Comment',checkintype=0)
req.Path = "/_api/web/GetFileByServerRelativeUrl('/Documents/penguins2.jpg')/CheckIn(comment='Comment',checkintype=0)";

// 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");

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

// 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());
    Debug.WriteLine("Failed");

    return;
}

// Show the successful XML response.
Debug.WriteLine(xml.GetXml());
Debug.WriteLine("Success.");

// A successful XML response looks like this:
// <?xml version="1.0" encoding="utf-8" ?>
