**1. 界面HTML**

**2. JavaScript代码（记得引用Jquery文件哦！！！）**

**3. Webservice代码**

[WebMethod]
    public string UploadExcel()
    {
           string result = "1";
           string filePath = "D:\\";//保存文件的地址
           var file = HttpContext.Current.Request.Files;
            try
            {
                for (int i = 0; i < file.Count; i++)
                {
                    var f = file[i];
    
                     filePath = Path.Combine(filePath, f.FileName);
    
                      f.SaveAs(filePath);
                }
                    result = "0";
                }
                catch(Exception ex)
                {
                    throw new Exception(ex.Message);
                }
                return result;
    }
