使用此代码浏览后，如何在我的表单上显示图像？ [英] How to display image on my form after browsing for it using this code?

问题描述

大家好

我正在使用这段代码来浏览图片。现在，如果有人知道 如何在浏览后在我的表单上显示图像 它使用此代码？ 

P.S。我不希望图像上传到服务器只是为了显示在用户的页面上

< input id =" fileInput"类型= QUOT;文件"风格= QUOT;显示：无;" /> 
< input type =" button" value ="选择文件！的onclick = QUOT;的document.getElementById（"的FileInput"）点击（）;" /> 

我的意思是以下编码的字形

 Dim ofd New OpenFileDialog 
 ofd.AddExtension = True 
 ofd.CheckFileExists = True 
 ofd.CheckPathExists = True 
 ofd.Filter =" Image Files | * .jpg; * .bmp; * .PNG; *&GIF QUOT。 
 
 ofd.FilterIndex = 1 
 ofd.InitialDirectory = My.Computer.FileSystem.SpecialDirectories.Desktop 
 ofd.Multiselect = True 
 ofd.RestoreDirectory = True 
 ofd.Title ="选择要添加到列表中的文件" 
 
如果ofd.ShowDialog（）= DialogResult.OK然后
 PictureBox1.Image = Image.FromFile（ofd.FileName）
结束如果

谢谢高级，我非常感谢任何帮助。

解决方案

< img> 元素的
src 属性可以设置为指向服务器上的图像文件。

Hi all

I am using this piece of code to browse for image. And now if any one know How to display image on my form after browsing for  it using this code? 

P.S. I do't want image to upload to server just to be displayed on user's page 

<input id="fileInput" type="file" style="display:none;" />
<input type="button" value="Choose Files!" onclick="document.getElementById('fileInput').click();" />

What I meant is simillar to the the following coded

Dim ofd As New OpenFileDialog
        ofd.AddExtension = True
        ofd.CheckFileExists = True
        ofd.CheckPathExists = True
        ofd.Filter = "Image Files|*.jpg;*.bmp;*.png;*.gif"

        ofd.FilterIndex = 1
        ofd.InitialDirectory = My.Computer.FileSystem.SpecialDirectories.Desktop
        ofd.Multiselect = True
        ofd.RestoreDirectory = True
        ofd.Title = "Select the files that you want to add to the the list"

        If ofd.ShowDialog() = DialogResult.OK Then
            PictureBox1.Image = Image.FromFile(ofd.FileName)
        End If

Thanks advanced and I really appreciate any help

解决方案

I think that the image has to be transferred (uploaded) to the server. Then the src attribute of an <img> element can be set to point to the image file on the server.
