C# 打开文件和打开文件夹（含源码工程）

一、演示

二、打开文件

private void chooseFileBtn_Click(object sender, EventArgs e)
{
    
    
    OpenFileDialog openFileDialog = new OpenFileDialog();
    openFileDialog.Title = "请选择文件";
    //openFileDialog.Filter = "文本文件(*.txt)|*.txt|所有文件(*.*)|*.*";
    openFileDialog.FilterIndex = 1;
    openFileDialog.Multiselect = false;
    if (openFileDialog.ShowDialog() == DialogResult.OK)
    {
    
    
        label1.Text = openFileDialog.FileName;
    }
}

三、打开文件夹

private void chooseFilePathBtn_Click(object sender, EventArgs e)
{
    
    
    FolderBrowserDialog folderBrowserDialog = new FolderBrowserDialog();
    folderBrowserDialog.Description = "请选择文件夹";
    if (folderBrowserDialog.ShowDialog() == DialogResult.OK)
    {
    
    
        label1.Text = folderBrowserDialog.SelectedPath;
    }
}

四、获取当前文件目录

private void Form1_Load(object sender, EventArgs e)
{
    
    
    label1.Text = Environment.CurrentDirectory;
}
