WPF中的图像问题。 [英] Problem with image in WPF.

问题描述

大家好



我有一个WPF应用程序，我想看一个图像到图像框。

我用这个代码来赢取表格来执行此操作

Hi guys

I have a WPF application and I want to see an image to image box.
I used this code to win forms to do this

 Public Sub picshow()
        Using cmd As New SqlCommand("Select * From Staff where StaffID='" & txtAA.Text & "'", GlobalClass.con)
            Using dr As SqlDataReader = cmd.ExecuteReader()
                Using dt As New DataTable
                    dt.Load(dr)
                    Try
                        Dim row As DataRow = dt.Rows(0)
                        Using ms As New MemoryStream(CType(row("Photo"), Byte()))
                            Dim img As Image = Image.FromStream(ms)
                            PictBox.Image = img '<-- Here is the problem "with Image"
                        End Using
                    Catch ex As Exception
                        GoTo err
                    End Try
                    Exit Sub
                End Using
            End Using
        End Using
        GlobalClass.con.Close()
err:
    End Sub

但它在WPF中不起作用

有人可以帮忙吗？

推荐答案

在WPF中使用图片



< Image Height = 305Horizo​​ntalAlignment =LeftMargin =14,53,0,0

Name =ImageControlStretch =FillVerticalAlignment =TopWidth =390/>



请看看进入下面的链接，知道如何从字节数组中获取BitmapImage

设置位图图像如下



ImageViewer1.Source = bitmap;
