I have a document library with a custom column. I want to add a file programatically, as well as a value for the custom column. I am posting the file via an ASP.NET application page. Here is what I have:

HttpPostedFile file = Request.Files["MyFile"];
web.AllowUnsafeUpdates = true;
SPFolder library = web.Folders["MyLibrary"];
SPFile spFile = library.Files.Add(file.FileName, file.InputStream);
/* The next two lines are an attempt to add the custom column value */
spFile.Item["CustomColumn"] = "CustomColumnValue";
web.AllowUnsafeUpdates = false;

It does add the file to the document library, but it does not add the value for the custom column. What am I doing wrong?

I found out what I was going wrong.

Instead of:

spFile.Item["CustomColumn"] = "CustomColumnValue";

do this:

spFile.Item.Properties["CustomColumn"] = "CustomColumnValue";
