本文介绍了txt文件的循环槽线通过FileUpload控件上传的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我要选择包含使用FileUpload控件弦线一个简单的.txt文件。但是,而不是实际保存文件我想环槽的每一行文本,并显示在ListBox控件中的每一行。

一个文本文件的例子:

的test.txt

123jhg345
182bdh774
473ypo433
129iiu454

什么是实现这一目标的最佳方式?

我到目前为止有:

 私人无效populateListBox()
{
  文件上传福= FileUpload1;  如果(fu.HasFile)
  {
    //循环槽的txt文件,并添加行ListBox1的
   }
 }


解决方案

 私人无效populateListBox()
{
    文件上传福= FileUpload1;
    如果(fu.HasFile)
    {
        StreamReader的读者=新的StreamReader(fu.FileContent);
        做
        {
            字符串TEXTLINE = reader.ReadLine();            //做你的编码
            //循环槽的txt文件,并添加行ListBox1的        }而(reader.Peek()!= -1);
        reader.Close();
    }
}

I want to select a simple .txt file that contains lines of strings using a FileUpload control. But instead of actually saving the file I want to loop trough each line of text and display each line in a ListBox control.

Example of a text file:

test.txt

123jhg345
182bdh774
473ypo433
129iiu454

What is the best way to accomplish this?

What I have so far:

private void populateListBox()
{
  FileUpload fu = FileUpload1;

  if (fu.HasFile)
  {
    //Loop trough txt file and add lines to ListBox1
   }
 }

解决方案

private void populateListBox() 
{
    FileUpload fu = FileUpload1; 
    if (fu.HasFile)  
    {
        StreamReader reader = new StreamReader(fu.FileContent);
        do
        {
            string textLine = reader.ReadLine();

            // do your coding 
            //Loop trough txt file and add lines to ListBox1  

        } while (reader.Peek() != -1);
        reader.Close();
    }
}
