1、服務端程式碼
private string DocumentFlowSwitchPath(byte[][] byteTuPian)
{
try
{
//按照年月日時分秒組成一個字串
string strFilePrefix = DateTime.Now.Year.ToString() +
DateTime.Now.Month.ToString() +
DateTime
2、頁面設計
3、。cs介面程式碼
//宣告一個byte[]型別的集合 List<byte[]> lstBytes1 = new List<byte[]>(); //點選儲存進行員工資訊的儲存 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]; } //點選選擇頭像按鈕事件，單開檔案 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]; //二進位制檔案存放的二進位制陣列 checkStream.Read(bytes, 0, Length); lstBytes1.Add(bytes); scrolls.Source = new BitmapImage(new Uri(openFileDialog.FileName, UriKind.Absolute)).Clone(); } } }
