最前面的话：Smobiler是一个在VS环境中使用.Net语言来开发APP的开发平台，也许比Xamarin更方便

一、目标样式

目标样式

我们要实现上图中的效果，需要如下的操作：

1.从工具栏上的“Smobiler Components”拖动一个ResourceUploader控件和一个ImageButton控件到窗体界面上

目标样式

2.ImageButton的Click事件

VB：   Private Sub imageButton1_Click(sender As Object, e As EventArgs)Handles imageButton1.Click       resourceUploader1.Show()   End Sub

C#：   private void imageButton1_Click(object sender, EventArgs e)   {       resourceUploader1.Show();   }

3.修改ResourceUploader控件的属性

a.MaxSelectCount属性

设置资源单次上传的最大数量，默认设置为“9”，一次最多上传9张图片，如图1；

b.QualityMode属性

获取或设置相机组件上传质量的模式，默认设置为“Custom”，即表示压缩上传和原图上传都支持，如图2；

若将该属性设置为“Compressed”，则表示只能压缩上传；

若将该属性设置为“Original”，则表示只能原图上传；

图1图2

c.Uploading事件

VB：   Dim imglist As List(Of String) = New List(Of String)   Private Sub resourceUploader1_Uploading(sender As Object, e As BarcodeData)Handles resourceUploader1.Uploading       Try           If e.IsError = False Then               e.SaveFile()               imglist.Add(e.ResourceID)               getImg()            End If       Catch ex As Exception           MessageBox.Show(ex.Message)      End Try    End Sub

C#：   private List<string> imglist = new List<string>();   private void resourceUploader1_Uploading(object sender, BinaryData e)   {       try       {           if (e.IsError == false)           {               e.SaveFile();               imglist.Add(e.ResourceID);               getImg();            }       }       catch (Exception ex)       {           MessageBox.Show(ex.Message);       }   }

注：调用ResourceUploader控件来获取图片

d.其他代码

VB：   Private Sub resourceuploader1_ImageCaptured(sender As Object, e As BarcodeData)Handles resourceuploader1.ImageCaptured        If imglist.Count > 0 & imglist.Count <= 9 Then           For i = 0 To imglist.Count Step 1               Select Case i                   Case 1                       img1.Visible = true                       btndelimg1.Visible = true                       img1.ResourceID = imglist(i - 1)                       img1.Refresh()                   Case 2                       img2.Visible = true                       btndelimg2.Visible = true                       img2.ResourceID = imglist(i - 1)                       img2.Refresh()                   Case 3                       img3.Visible = true                       btndelimg3.Visible = true                       img3.ResourceID = imglist(i - 1)                       img3.Refresh()                   Case 4                       img4.Visible = true                       btndelimg4.Visible = true                       img4.ResourceID = imglist(i - 1)                       img4.Refresh()                   Case 5                       img5.Visible = true                       btndelimg5.Visible = true                       img5.ResourceID = imglist(i - 1)                       img5.Refresh()                   Case 6                       img6.Visible = true                       btndelimg6.Visible = true                       img6.ResourceID = imglist(i - 1)                       img6.Refresh()                   Case 7                       img7.Visible = true                       btndelimg7.Visible = true                       img7.ResourceID = imglist(i - 1)                       img7.Refresh()                   Case 8                       img8.Visible = true                       btndelimg8.Visible = true                       img8.ResourceID = imglist(i - 1)                       img8.Refresh()                                          Case 9                       img9.Visible = true                       btndelimg9.Visible = true                       img9.ResourceID = imglist(i - 1)                       img9.Refresh()              End Select            Next       End If   End Sub

C#：   private void getImg()   {       if (imglist.Count > 0 & imglist.Count <= 9)       {           for (int i = 1; i <= imglist.Count; i++)           {               switch (i)               {                   case 1:                       img1.Visible = true;                       btndelimg1.Visible = true;                       img1.ResourceID = imglist[i - 1];                       img1.Refresh();                       break;                   case 2:                       img2.Visible = true;                       btndelimg2.Visible = true;                       img2.ResourceID = imglist[i - 1];                       img2.Refresh();                       break;                   case 3:                       img3.Visible = true;                       btndelimg3.Visible = true;                       img3.ResourceID = imglist[i - 1];                       img3.Refresh();                       break;                   case 4:                       img4.Visible = true;                       btndelimg4.Visible = true;                       img4.ResourceID = imglist[i - 1];                       img4.Refresh();                       break;                   case 5:                       img5.Visible = true;                       btndelimg5.Visible = true;                       img5.ResourceID = imglist[i - 1];                       img5.Refresh();                       break;                   case 6:                       img6.Visible = true;                       btndelimg6.Visible = true;                       img6.ResourceID = imglist[i - 1];                       img6.Refresh();                       break;                   case 7:                       img7.Visible = true;                       btndelimg7.Visible = true;                       img7.ResourceID = imglist[i - 1];                       img7.Refresh();                       break;                   case 8:                       img8.Visible = true;                       btndelimg8.Visible = true;                       img8.ResourceID = imglist[i - 1];                       img8.Refresh();                       break;                   case 9:                       img9.Visible = true;                       btndelimg9.Visible = true;                       img9.ResourceID = imglist[i - 1];                       img9.Refresh();                       break;               }           }       }   }
