推荐答案

您可以使用以下代码放置表单按钮并为其创建单击处理程序:

You can put on your form button and create click handler to it with the following code:

private void buttonGetFile_Click(object sender, EventArgs e)
{
    OpenFileDialog dialog = new OpenFileDialog();
    dialog.Filter = "Text files | *.txt"; // file types, that will be allowed to upload
    dialog.Multiselect = false; // allow/deny user to upload more than one file at a time
    if (dialog.ShowDialog() == DialogResult.OK) // if user clicked OK
    {
        String path = dialog.FileName; // get name of file
        using (StreamReader reader = new StreamReader(new FileStream(path, FileMode.Open), new UTF8Encoding())) // do anything you want, e.g. read it
        {
                // ...
        }
    }
}
