前台：

<div id="Upload">

    <asp:FileUpload ID="FileUpload1" runat="server" />

    <asp:Button ID="Button1" runat="server" Text="上载到文档库" onclick="Button1_Click" />
        <br />
        <asp:Panel ID="Panel1" runat="server"></asp:Panel>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
     
    </div>

Button1_Click事件：

   protected void Button1_Click(object sender, EventArgs e)
        {
            this.UploadFileToDocLib(SPContext.Current.Web, "456", this.FileUpload1, 1);
        }

UploadFileToDocLib的方法：

public void UploadFileToDocLib(SPWeb web, string docLibName, FileUpload fUpload, int itemId)
        {
            string FileName = FileUpload1.PostedFile.FileName;
            if (FileName == "")
            {
                Page.ClientScript.RegisterClientScriptBlock(this.GetType(), Guid.NewGuid().ToString(), string.Format("<script>alert('上传文件不能为空!')</script>"));

            }
            else
            { 
            SPList list = web.Lists.TryGetList(docLibName);

            SPDocumentLibrary docLib = (SPDocumentLibrary)list;

            if (fUpload.HasFile)
            {


                string file_type = FileUpload1.PostedFile.ContentType;
                string file_KB = FileUpload1.PostedFile.ContentLength.ToString() + "KB<br>";
                string fn = System.IO.Path.GetFileName(fUpload.PostedFile.FileName);

                System.IO.Stream stm = fUpload.PostedFile.InputStream;
                int iLength = (int)stm.Length;

                if (iLength > 0)
                {

                    SPFolder rootFolder = docLib.RootFolder;

                    Byte[] filecontent = new byte[iLength];

                    stm.Read(filecontent, 0, iLength);
                    try
                    {

                        SPFile f = rootFolder.Files.Add(fn, filecontent);

                        SPListItem item = f.Item;

                        item["ItemID"] = itemId;

                        item.SystemUpdate();
                        stm.Close();


                        Page.ClientScript.RegisterClientScriptBlock(this.GetType(), Guid.NewGuid().ToString(), string.Format("<script>alert('成功上传!')</script>"));

                        string URL = "http://amid01110/456/" + FileName + " ";
                        ////循环添加label
                        for (int i = 0; i < 1; i++)
                        {
                            Label l = new Label();
                            l.ID = "lbl" + i;
                            l.Text = "</br>" + "<a  href='" + URL + "' target='_blank' >" + fn + "</a>" + "大小" + file_KB + "上传文件成功";//label属性texbox的值
                            Panel1.Controls.Add(l);
                        }
                      

                    }

                    catch (Exception) { Page.ClientScript.RegisterClientScriptBlock(this.GetType(), Guid.NewGuid().ToString(), string.Format("<script>alert('文件名存在!')</script>")); }
