问题描述

如果我们点击btnfolderdailog然后选择文件然后点击Ok然后它的井。

如果我们点击取消按钮然后发生错误：-ArgumentException was未处理



路径不合法。

Hi,
If we click btnfolderdailog then select the file and click "Ok" then its well.
If we click cancel button then occurred Error:-ArgumentException was Unhandled

The path is not of a legal form.

folderBrowserDialog1.ShowDialog();

            totalfolderfileCount = System.IO.Directory.GetFiles(folderBrowserDialog1.SelectedPath, "*").Length;
            string[] array = Directory.GetFiles(folderBrowserDialog1.SelectedPath, "*.bdf*");
            txtInputPath.Text = folderBrowserDialog1.SelectedPath;

推荐答案

你调用ShowDialog，然后使用folderBrowserDialog1.SelectedPath属性。



你没有处理取消 - 你就好像一切都好。每当你在任何事情上调用ShowDialog时，你应该处理对话结果并根据结果工作。

You call ShowDialog and then use folderBrowserDialog1.SelectedPath property.

You didn't handle the canceling - you're just going as if everything is fine. Every time you call ShowDialog on anything, you should process dialog result and work depending on that result.

if (folderBrowserDialog1.ShowDialog() == DialogResult.OK) {
    totalfolderfileCount = System.IO.Directory.GetFiles(folderBrowserDialog1.SelectedPath, "*").Length;
            string[] array = Directory.GetFiles(folderBrowserDialog1.SelectedPath, "*.bdf*");
            txtInputPath.Text = folderBrowserDialog1.SelectedPath;

}
