c# - 在 Windows 应用程序中显示结果

Question

我对如何在 Windows 窗体应用程序中显示结果感到困惑。

private void btnBrowse_Click(object sender, EventArgs e)
        {
            DialogResult result = openFileDialog1.ShowDialog();
            if (result == DialogResult.OK) 
            {
                txtFileName.Text = openFileDialog1.FileName;
            }
        }

        private void btn_search_Click(object sender, EventArgs e)
        {

            var result = File.ReadAllLines(@txtFileName.Text).Select(s => s.Contains(txt_search.Text));


        }

我想将搜索结果显示为列表。谁能帮我？

一种简单的方法是只设置一个文本框，该文本框会在搜索完成后更新。

private void richTextBox1_TextChanged(object sender, EventArgs e)
    {
        richTextBox1.SelectionStart = richTextBox1.Text.Length; //Set the current caret position at the end
        richTextBox1.ScrollToCaret(); //Now scroll it automatically
    }

private void btnBrowse_Click(object sender, EventArgs e)
    {
        DialogResult result = openFileDialog1.ShowDialog();
        if (result == DialogResult.OK) 
        {
            txtFileName.Text = openFileDialog1.FileName;
        }
    }

    private void btn_search_Click(object sender, EventArgs e)
    {

        var result = File.ReadAllLines(@txtFileName.Text).Select(s => s.Contains(txt_search.Text));

    this.richTextBox1.AppendText(result.ToString()); //---> Appends the Text to the Rich Text Box, you may want to change the variable result(i hope its not a collection)
    }
