我有浏览按钮，RichtextBox&表单中的Progressbar [openfiledialog，backgroundworker]。

任务

First Thread读取目录文本文件并放入多行文本框

另一个显示进度条的线程根据目录中的文件数量工作。





private void btnBrowse_Click（对象发送者，EventArgs e）

{

openFileandRead（）;

}

public void openFileandRead（）< br $>
{

流myStream = null;

OpenFileDialog Dialog = new OpenFileDialog（）;

Dialog.Title =打开文本文件;

Dialog.Filter =TXT文件| * .txt;

Dialog.Multiselect = true; //允许在openfiledialog中选择多个文件



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

{

尝试

{

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

{

使用（myStream）

{



string [] filePaths = Directory.GetFiles（@D：\ TestTxtFiles ，* .txt，SearchOption.AllDirectories）;

foreach（filePaths中的字符串文件）

{

rtxtFile.AppendText（System .IO.File.ReadAllText（file））;

Thread.Sleep（2000）;

}

}

$

}

catch（Exception ex）

{

MessageBox.Show（错误：无法从磁盘读取文件。原始错误：+ ex.Message）;

}

}
