获取单击按钮时显示的文本文件列表 [英] Getting a list of text files to show when clicked on a button

问题描述

我希望当我点击一个名为Dutch的按钮时，它会加载到指定路径中的所有文件中，并在下拉列表中显示它们，您可以在其中选择其中一个文件，然后将其加载到固定文本框。

问题是，当我尝试这个时，它根本没有显示下拉列表中的文件名。

我用的是我从网站上获得的自定义控件：使用自定义控件的ButtonDropDown（ButtonDropDownMenu控件） [ ^ ]

但我不知道如何实施这些文本文件的自动加载。

所以我需要的是一种在下拉菜单中自动加载文件名的方法，当我点击它时，它会将其加载到文本框中。



这是我到目前为止所得到的。

I would like that when I click on a button called "Dutch" that it loads in all the files in a specified path and show them in a drop down list where you can chose 1 of those files that it then loads into a fixed textbox.
The problem is that when I try this, it doesn''t show me the file names in the drop down list at all.
I do use a custom control I got from the website : ButtonDropDown using Custom Control (ButtonDropDownMenu Control)[^]
But I don''t know how to implement the automatic loading of those text files.
So what I need is a way to automaticly load the file-names in the drop down menu and when I click on one it loads it into a text box.

This is what I got so far.

private void Dutch_Click(object sender, EventArgs e)
        {
            string[] dirs = Directory.GetFileSystemEntries(@"C:\Users\a961835\Programming","*.txt");
            foreach (string dir in dirs)
            {
                textBox1.Text = dir;
            }
            //string s = File.ReadAllText(@"C:\Users\a961835\Programming");
            //textBox1.Text = s;
        }

推荐答案

现在试试这段代码，

now try this code,

string[] Filelistarray = Directory.GetFiles(@"D:\", "*.txt");
DataTable dt = new DataTable();
dt.Columns.Add("FileName");
foreach (string FileName in Filelistarray)
{
    DataRow dr = dt.NewRow();
    string filenameWithoutPath = Path.GetFileName(FileName);
    dr["FileName"] = filenameWithoutPath;
    dt.Rows.Add(dr);
}

DropDownList1.DataSource = dt;
DropDownList1.DataBind();

最终我使用了SoMad中的代码，但稍微调整了一下;）仍然感谢man：D

Eventually I used the code from SoMad but adjusted it a little bit ;) Still loads of thanks man :D

private void Dutch_Click(object sender, EventArgs e)
        {
            
            string[] Filelistarray = Directory.GetFiles(@"C:\Users\a961835\Programming", "*.txt");
            DataTable dt = new DataTable();
            dt.Columns.Add("FileName");
            foreach (string FileName in Filelistarray)
            {
                DataRow dr = dt.NewRow();
                string filenameWithoutPath = Path.GetFileName(FileName);
                dr["FileName"] = filenameWithoutPath;
                dt.Rows.Add(dr);
            }

            DropDownList.DataSource = dt;            
            DropDownList.DisplayMember = "FileName";            

        }

hi，

试试这个..



添加命名空间



使用System.IO;

try this..

add namespace

using System.IO;

string[] Filelistarray = Directory.GetFiles(@"D:\", "*.txt");

foreach (string FileName in Filelistarray)
{
    textBox1.Text += FileName;
}
