There might be
times when we will have to specify a content type for a file that is programmatically
uploaded to a SharePoint library through CSOM. This blog post explains the steps
involved in setting the custom content type through CSOM code. In order to set
the content type we will be using the ParseAndSetFieldValue method of the list
item and set the id of our desired content type to the ContentTypeId property.
The first step is to get the content type if of our content type. This is done by looping through all the content types attached to the library and getting the id of the particular content type.

string serverUrl = "SharePoint
Site URL";
String login = "user name";
String password = "password";
string listUrlName = "Library
Name";
string customcontenttypename = "Content
Type Name";
ClientContext context = new ClientContext(serverUrl);
var passWord = new SecureString();
foreach (char c in password.ToCharArray()) passWord.AppendChar(c);
context.Credentials = new SharePointOnlineCredentials(login,
passWord);
List splist = context.Web.GetList(listUrlName);
context.Load(splist);
context.Load(splist.ContentTypes);
context.ExecuteQuery();
ContentType ctcustom = null;
foreach (ContentType ct in splist.ContentTypes)
{
if (ct.Name == customcontenttypename)
{
ctcustom
= ct;
break;
}
}
Then we upload the
file to the library
var folder =
context.Web.GetFolderByServerRelativeUrl(listUrlName);
context.Load(folder);
var files = folder.Files;
context.Load(files);
string filepath = @"File Path";
FileInfo fi = new FileInfo(filepath);
var fci = new FileCreationInformation
{
Url =
fi.Name,
Overwrite
= true,
Content
= System.IO.File.ReadAllBytes(filepath)
};
var file = files.Add(fci);
file.ListItemAllFields.ParseAndSetFieldValue("ContentTypeId",
ctcustom.Id.ToString());
file.ListItemAllFields.Update();
context.Load(file);
context.ExecuteQuery();
