Question

我想在点击按钮时打开文件选择窗口。

如何在不使用文件上传器控件的情况下打开文件选择窗口？

Answer 1

请尝试以下代码：

private void button1_Click(object sender, EventArgs e)
    {
        OpenFileDialog openFileDialog1 = new OpenFileDialog();

        // Set filter options and filter index.
        openFileDialog1.Filter = "Text Files (.txt)|*.txt|All Files (*.*)|*.*";
        openFileDialog1.FilterIndex = 1;

        openFileDialog1.Multiselect = true;

        // Call the ShowDialog method to show the dialog box.
         openFileDialog1.ShowDialog();

        // Process input if the user clicked OK.

    }

如果对您有帮助，请将答案标记为正确。
