(C#)WPF保存图片，将图片提交到服务端进行保存

1、服务端代码

 private string DocumentFlowSwitchPath(byte[][] byteTuPian)

    {

        try

        {

            //按照年月日时分秒组成一个字符串

            string strFilePrefix = DateTime.Now.Year.ToString() +

                                  DateTime.Now.Month.ToString() +

                                  DateTime.Now.Day.ToString() + 

                                  DateTime.Now.Hour.ToString() +

                                  DateTime.Now.Minute.ToString() + 

                                  DateTime.Now.Second.ToString() +

                                  DateTime.Now.Millisecond.ToString();

            //图片名称变量

            string strFileName = "";

            for (int i = 0; i < byteTuPian.Length; i++)//遍历二进制的数组的数组

            {

                string strRiQiWenJian = strFilePrefix + i.ToString() + ".png";

                //获取根目录磁盘路径

                string strBaoCunLuJing = System.AppDomain.CurrentDomain.BaseDirectory;

                strBaoCunLuJing = strBaoCunLuJing + "image\\" + strRiQiWenJian;

                FileInfo fi = new System.IO.FileInfo(strBaoCunLuJing);

                FileStream fs;

                fs = fi.OpenWrite();

                fs.Write(byteTuPian[i], 0, byteTuPian[i].Length);

                fs.Close();

                strFileName += strRiQiWenJian;

            }

            return strFileName;

        }

        catch

        {

            return null;

        }

    }  

2、页面设计

 

 

3、。cs界面代码

 //声明一个byte[]类型的集合

  List<byte[]> lstBytes1 = new List<byte[]>();

 //点击保存进行员工信息的保存

    private void btnUpdate_Click(object sender, RoutedEventArgs e)

    {

            byte[][] HeadPhoto = new byte[lstBytes1.Count][];

            for (int i = 0; i < lstBytes1.Count; i++)

            {

                HeadPhoto[i] = lstBytes1[i];

            }               

            DataTable dt = bll_Emloyee.DocumentFlowSwitchPath(HeadPhoto).Tables[0];        

       

    }  

    //点击选择头像按钮事件，单开文件

    private void btn_openFile_Click(object sender, RoutedEventArgs e)

    {

        Stream checkStream = null;

        Microsoft.Win32.OpenFileDialog openFileDialog = new Microsoft.Win32.OpenFileDialog();

        openFileDialog.Multiselect = false;

        openFileDialog.Filter = "All Image Files | *.*";

        if ((bool)openFileDialog.ShowDialog())

        {

            lstBytes1.Clear();

            if ((checkStream = openFileDialog.OpenFile()) != null)

            {

                int Length = (int)checkStream.Length;

                byte[] bytes = new byte[Length];  //二进制文件存放的二进制数组

                checkStream.Read(bytes, 0, Length);

                lstBytes1.Add(bytes);

                scrolls.Source = new BitmapImage(new Uri(openFileDialog.FileName, UriKind.Absolute)).Clone();                    }

        }

    }
