Silverlight将Excel导入到SQLserver数据库

最近纠结于读取Excel模板数据，将数据导入SQLServer的Silverlight实现，本文将实现代码贴出，作为一个简单的例子，方便各位：

1.先设计前台界面新建Silverlight5.0应用程序，出现MainPage.xaml，代码如下所示：

<UserControl x:Class="Excel导入SQLServer数据库.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    Width="400" Height="117">

    <Grid x:Name="LayoutRoot" Background="White">
        <ListBox Name="listBox1" HorizontalAlignment="Right" VerticalAlignment="Center" Width="239" Height="23" Margin="0,9,11,47">
        </ListBox>
        <Button x:Name="UploadButton" Content="确认上传" Click="UploadButton_Click" Width="75" Height="23" HorizontalAlignment="Right" Margin="0,37,12,18" />
        <Button x:Name="OpenButton" Content="选择本地Excel文件" Click="OpenButton_Click" Width="116" Height="23" HorizontalAlignment="Right" Margin="0,8,258,47" />
    </Grid>
</UserControl>

其效果图，如下所示：

其后台MainPage.xaml.cs代码,如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using System.IO;

namespace Excel导入SQLServer数据库
{
    public partial class MainPage : UserControl
    {
        //在此先定义一个List;
        List<FileInfo> filesToUpload;
        public MainPage()
        {
            InitializeComponent();
        }

        /// <summary>
        /// 确认上传
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void UploadButton_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                if (filesToUpload == null)
                {
                    return;
                }
                foreach (FileInfo file in filesToUpload)
                {
                    //Define the Url object for the Handler
                    UriBuilder handlerUrl = new UriBuilder("http://localhost:5952/UploadFileHandler.ashx");//自己的端口
                    //Set the QueryString
                    handlerUrl.Query = "InputFile=" + file.Name;
                    FileStream FsInputFile = file.OpenRead();
                    //Define the WebClient for Uploading the Data
                    WebClient webClient = new WebClient();
                    //Now make an async class for writing the file to the server
                    //Here I am using Lambda Expression
                    webClient.OpenWriteCompleted += (s, evt) =>
                    {
                        UploadFileData(FsInputFile, evt.Result);
                        evt.Result.Close();
                        FsInputFile.Close();
                        MessageBox.Show("上传成功！");
                        listBox1.ItemsSource = "";

                    };
                    webClient.OpenWriteAsync(handlerUrl.Uri);
                }

            }
            catch (System.Exception)
            {

                throw;
            }
        }

        private void UploadFileData(Stream inputFile, Stream resultFile)
        {
            byte[] fileData = new byte[4096];
            int fileDataToRead;
            while ((fileDataToRead = inputFile.Read(fileData, 0, fileData.Length)) != 0)
            {
                resultFile.Write(fileData, 0, fileDataToRead);
            }
        }

        /// <summary>
        /// 打开文件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void OpenButton_Click(object sender, RoutedEventArgs e)
        {
            try
            {
                OpenFileDialog fileDialog = new OpenFileDialog();
                fileDialog.Multiselect = false;
                //这里只写了Excel有关格式，可以根据需要添加其他格式
                fileDialog.Filter = "Excel Files(*.xls,*.xlsx)|*.xls";
                bool? result = fileDialog.ShowDialog();
                if (result != null)
                {
                    if (result == true)
                    {
                        filesToUpload = fileDialog.Files.ToList();
                        listBox1.ItemsSource = filesToUpload;
                    }
                    else
                        return;
                }
            }
            catch (System.Exception)
            {

                throw;
            }
        }
    }
}

注意：将其中的端口号跟自己的程序相对应，如下图：

接着，在.web目录下，新建FilesServer文件夹，和UploadFileHandler.ashx的一般处理程序，如下图：

其中，UploadFileHandler.ashx.cs中内容如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Data.OleDb;
using System.Data;
using System.Data.SqlClient;
using System.IO;

namespace Excel导入SQLServer数据库.Web
{
    /// <summary>
    /// UploadFileHandler 的摘要说明
    /// </summary>
    public class UploadFileHandler : IHttpHandler
    {

        public void ProcessRequest(HttpContext context)
        {
            try
            {
                string filename = context.Request.QueryString["InputFile"].ToString();
                using (FileStream fileStream = File.Create(context.Server.MapPath("~/FilesServer/" + filename)))
                {
                    byte[] bufferData = new byte[4096];
                    int bytesToBeRead;
                    while ((bytesToBeRead = context.Request.InputStream.Read(bufferData, 0, bufferData.Length)) != 0)
                    {
                        fileStream.Write(bufferData, 0, bytesToBeRead);
                    }
                    fileStream.Close();

                }
                //===========用于对上传的EXCEL文件插入到SQL数据库中===============

                string strPath = context.Server.MapPath("~/FilesServer/" + filename);
                //string mystring = "Provider = Microsoft.Jet.OleDb.4.0 ; Data Source = ‘" + strPath + "‘;Extended Properties=Excel 8.0";//之前版本链接格式
                string mystring = "Provider =  Microsoft.ACE.OLEDB.12.0 ; Data Source = ‘" + strPath + "‘;Extended Properties=‘Excel 12.0;HDR=Yes;IMEX=1;‘";//office2010链接格式
                OleDbConnection cnnxls = new OleDbConnection(mystring);
                if (cnnxls.State == ConnectionState.Closed)
                {
                    cnnxls.Open();
                }
                OleDbDataAdapter myDa = new OleDbDataAdapter("select * from [Sheet1$]", cnnxls);
                DataSet myDs = new DataSet();
                myDa.Fill(myDs);
                string ConnStr = "Data Source=WIN-FKM3JDGK01I\\MYSQLR2;Initial Catalog=CDDB;Persist Security Info=True;User ID=sa;Password=123456";
                SqlConnection MyConn = new SqlConnection(ConnStr);
                MyConn.Open();
                //读取Excel中的数据
                string xuehao = myDs.Tables[0].Rows[0][0].ToString();
                string xingming = myDs.Tables[0].Rows[0][1].ToString();
                string strSQL = "insert into CDDB.dbo.Student(XUEHAO,NAME) values (‘" + xuehao + "‘,‘" + xingming + "‘)";
                SqlCommand myComm1 = new SqlCommand(strSQL, MyConn);
                myComm1.ExecuteNonQuery();
                MyConn.Close();
                cnnxls.Close();
            }
            catch (Exception)
            {

                throw;
            }

        }

        public bool IsReusable
        {
            get
            {
                return false;
            }
        }
    }
}

注意事项，参考下图：

如此，可以将Excel中的数据写入SQLserver数据库中，经测试，可行，附上代码，仅供参考！
