请参考以下代码：

SPWeb oWeb = SPContext.Current.Web;
SPList lstTarget = oWeb.Lists.TryGetList("DDC");

Hashtable metaData = new Hashtable();

metaData.Add("Field1 Name", "Field1 Value");
metaData.Add("Field2 Name", "Field2 Value");
metaData.Add("Field3 Name", "Field3 Value");

byte[] bytes = File.ReadAllBytes("c:\folder\myfile.txt"); //Set path to file to be uploaded in document library.

oWeb.AllowUnsafeUpdates = true;
SPFile destfile = lstTarget.RootFolder.Files.Add("myfile.txt", bytes, metaData, true);
oWeb.AllowUnsafeUpdates = false;
