1.前端用ListBox載入顯示多張圖片
1 <ListBox Name="lbHeadImages" Grid.Row="1" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
2 <ListBox.ItemTemplate>
3 <DataTemplate>
4 <Grid >
5 <Rectangle Fill="#fff">
6 <Rectangle.Effect>
7 <DropShadowEffect Opacity="0.5" ShadowDepth="0"/>
8 </Rectangle.Effect>
9 </Rectangle>
10 <StackPanel Margin="2">
11 <Image Stretch="UniformToFill" Width="100" Height="120" VerticalAlignment="Center" HorizontalAlignment="Center"
12 Source="{Binding Image,Mode=TwoWay,NotifyOnSourceUpdated=True}"
13 MouseLeftButtonDown="Image_MouseLeftButtonDown"></Image>
14 </StackPanel>
15 </Grid>
16 </DataTemplate>
17 </ListBox.ItemTemplate>
18 <ListBox.ItemsPanel>
19 <ItemsPanelTemplate>
20 <WrapPanel Name="wrapPanel" HorizontalAlignment="Stretch" />
21 <!--<UniformGrid Columns="6"></UniformGrid>-->
22 </ItemsPanelTemplate>
23 </ListBox.ItemsPanel>
24 </ListBox>
2.客戶端——選擇圖片(可選擇多張)，前臺載入顯示
1 private void btnSelectBehindImage_Click(object sender, RoutedEventArgs e)
2 {
3 OpenFileDialog openFileDialog = new OpenFileDialog();
4 openFileDialog.Multiselect = true;
5 openFileDialog.Filter = "All Image Files|*.jpg;*.png";
6 if ((bool)openFileDialog.ShowDialog()) {
7 if (openFileDialog.OpenFile() != null) {
8 behindImages.Clear();
9 string[] fileNames = openFileDialog.FileNames;
10 List<FinishProRptCheckVM.ImageRow> items = new List<FinishProRptCheckVM.ImageRow>();
11 for (int i = 0; i < fileNames.Count(); i ++) {
12 string filePath = fileNames[i];
13 var size = new FileInfo(filePath).Length / 1024 /1024; //獲取檔案大小（M）
14 if (size >= 1) { MessageBox.Show("上傳圖片大小不能超過1M!");return; }
15 byte[] bytes = File.ReadAllBytes(filePath);
16 behindImages.Add(bytes);
17
18 FinishProRptCheckVM.ImageRow row = new FinishProRptCheckVM.ImageRow() { Image = new BitmapImage(new Uri(filePath))};
19 items.Add(row);
20 }
21 lbBehindImages.ItemsSource = items;
22 }
23 }
24 }
3.客戶端上傳圖片
1 private bool UploadImage(string bill_no)
2 {
3 //上傳伺服器資料夾
4 string url = "/api/qc/iqc/experimentrptservice/uploadfile";
5 var result = Framework.PostData(url, lstBytes1, behindImages, bill_no);
6 if (result.success && result.data)
7 {
8 return true;
9 }
10 else
11 {
12 return false;
13 }
14 }
4.服務端儲存圖片到伺服器資料夾
1 public static object UploadFile(List<byte[]> headerPhoto,List<byte[]> behindPhoto,string billNo) {
2 try
3 {
4 //獲取儲存檔案的資料夾路徑
5 string filePath = "D:\\image\\";
6 if (!System.IO.Directory.Exists(filePath))//資料夾不存在建立資料夾
7 {
8 Directory.CreateDirectory(filePath);
9 }
10 else {//資料夾存在，找對應實驗是否存在上傳過的圖片,存在則刪除
11 string[] strDataFiles = Directory.GetFiles(filePath);
12 var imageFiles = from a in strDataFiles where a.Contains(billNo) && (a.EndsWith(".png") || a.EndsWith(".jpg")) select a;
13 foreach (string imagePath in imageFiles) {
14 File.Delete(imagePath);
15 }
16 }
17 //儲存實驗前圖片
18 for (int i = 0; i < headerPhoto.Count; i++)//遍歷二進位制的陣列的陣列
19 {
20 string strRiQiWenJian = "實驗前" + i.ToString() + "_" + billNo + ".png";
21 string strBaoCunLuJing = "D:\\image\\" + strRiQiWenJian;
22 FileInfo fi = new FileInfo(strBaoCunLuJing);
23 FileStream fs;
24 fs = fi.OpenWrite();
25 fs.Write(headerPhoto[i], 0, headerPhoto[i].Length);
26 fs.Flush();
27 fs.Close();
28 }
29 return true;
30 }
31 catch
32 {
33 return false;
34 }
35 }
5.客戶端，進入介面，初始化從伺服器載入對應圖片顯示
1 public void LoadImages (){
2 string url = "/api/qc/iqc/experimentrptservice/loadimages?bill_no=" + ParamModel.BILL_NO;
3 var result = Framework.GetData(url);
4 if (result.success){
5 lstBytes1 = JsonConvert.DeserializeObject<List<byte[]>>(result.data.HeaderBytePic.ToString());
6 behindImages = JsonConvert.DeserializeObject<List<byte[]>>(result.data.BehindBytePic.ToString());
7
8 //載入實驗前圖片
9 List<FinishProRptCheckVM.ImageRow> headerImages = new List<FinishProRptCheckVM.ImageRow>();
10 for (int i = 0; i < lstBytes1.Count;i++) {
11 BitmapImage img = new BitmapImage();
12 img.BeginInit();
13 img.StreamSource = new MemoryStream(lstBytes1[i]);
14 img.EndInit();
15 //img.Freeze();
16 FinishProRptCheckVM.ImageRow row = new FinishProRptCheckVM.ImageRow() { Image = img };
17 headerImages.Add(row);
18 }
19 lbHeadImages.ItemsSource = headerImages;
20 }
21 }
6.效果圖
