具有“浏览"窗口

问题描述

您好，
我正在尝试提供一个提示窗口，供您使用按钮进一步选择文件. 这里是corr.按钮单击的事件.现在，在我单击corr之后.按钮，会话将结束.

私有 无效 bt_browse_Clicked( 对象 发送者， EventArgs e)

Hi,
I'm trying to have a prompt window for further choosing a file using a button. Here is the corr. button-clicked event. Now after I've clicked the corr. button to go further, the session will just end.

private void bt_browse_Clicked(object sender, EventArgs e)

{

Stream myStream = 空 ;

Stream myStream = null;

OpenFileDialog openFileDialog1 = 新 OpenFileDialog ();

OpenFileDialog openFileDialog1 = new OpenFileDialog();

openFileDialog1.InitialDirectory = " c:\\" ;

openFileDialog1.InitialDirectory = "c:\\";

openFileDialog1.Filter = " JPG文件(* .jpg)| * .jpg |全部文件(*.*)| *.*" ;

openFileDialog1.Filter = "JPG files (*.jpg)|*.jpg|All files (*.*)|*.*";

openFileDialog1.FilterIndex = 2;

openFileDialog1.FilterIndex = 2;

openFileDialog1.RestoreDirectory = true ;

openFileDialog1.RestoreDirectory = true;

if (openFileDialog1.ShowDialog ()== DialogResult .确定)

if (openFileDialog1.ShowDialog() == DialogResult.OK)

{

尝试

try

{

if (((myStream = openFileDialog1.OpenFile())！= null )

if ((myStream = openFileDialog1.OpenFile()) != null)

{

使用 (myStream)

using (myStream)

{

tb_photo_fl.Text = openFileDialog1.FileName;

tb_photo_fl.Text = openFileDialog1.FileName;

}

}

}

捕获 ( 例外 例如)

catch (Exception ex)

{

MessageBox .Show( "错误:无法从磁盘读取文件.原始错误:" +例如消息)；

MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);

}

}

}

有人知道这个问题的原因吗? (我使用的是2008 Express版本)

Does anyone know the reason of this issue? (I'm using version 2008 Express)
