SharePoint 2010 - sharepoint-2010

Question

We are working on an assignment to create a web application using SharePoint 2010 which is totally new to all of us.
My challenge is creating a file upload form. I used SharePoint designer to drag the upload texbox and button controls from the ASP.NET tool box. I don't know what to do next because I need the files to go where I want.
Here is the code that I have for the control I palced on the page:
<form id="form1" runat="server">
<asp:FileUpload runat="server" id="FileUpload1" /><br />
<br />
<asp:Button runat="server" Text="Upload" id="Button1" Width="88px" />
</form>

This routine will upload a single file assuming you've implemented the FileUpload control on your page. the routine gets the file name from the FileUpload control and adds it to a SharePoint list:
protected void UploadButton_Click(object sender, EventArgs e)
//=================================================
// upload the file selected in the upload button to the library
//
//=================================================
{
string docLibName = "/documents/Forms/AllItems.aspx";
if (FileUpload.HasFile)
{
try
{
int orderID = Convert.ToInt32(ViewState["OrderID"].ToString());
string status = ddlDocumentStatus.SelectedValue;
string docType = ddlDocumentType.SelectedValue;
// Read the file contents into a byte stream
string filename = FileUpload.FileName;
byte[] contents = new byte[FileUpload.FileContent.Length];
System.IO.Stream myStream;
int fileLen = FileUpload.PostedFile.ContentLength;
myStream = FileUpload.FileContent;
myStream.Read(contents, 0, fileLen);
// Upload the file to "Documents" Library
using (SPSite oSite = new SPSite(_siteURL))
using (SPWeb oWeb = oSite.OpenWeb())
{
docLibName = _siteURL + docLibName;
SPWeb site = new SPSite(docLibName).OpenWeb();
// Copy the file to the sharepoint library
SPFolder myLibrary = oWeb.Folders["Documents"];
// try checking out the file, if it doesn't exist, create it:
SPFile spfile = null;
try
{
spfile = oWeb.GetFile(_siteURL + "/Documents/" + filename);
if (spfile.Exists)
{
spfile.CheckOut();
myLibrary.Files.Add(filename, myStream, true);
}
else // create a new document
{
spfile = myLibrary.Files.Add(filename, myStream, true);
}
SPListItem document = spfile.Item;
// Copy the metadata to the document
//spfile.Item;
// update the metadata for the document here
document["Columns Name"] = some_string_value;
document["Document Type"] = docType;
myLibrary.Update();
document.Update();
spfile.CheckIn("Document updated on " + DateTime.Today.ToString());
}
catch (Exception ex)
{
string errorMessage = ex.Message;
}
// update the sharepoint list
SPList docLib = oWeb.Lists["Documents"];
AddDocuments(orderID, docLib);
lblDocumentMessage.Text = "Document uploaded!";
}// using - Disposes Site and web
}// try
catch (Exception ex)
{
string errorMessage = ex.Message;
lblDocumentMessage.Text = "Document upload error: " + errorMessage;
}
}
}
