我在关闭saveFileDialog时遇到问题。当我单击"取消"时,窗口再次出现。这是我的代码:

        private void SaveAsItem_Click(object sender, EventArgs e)
    {
        saveFileDialog1.FileName = "untitled";
        saveFileDialog1.Filter = "Text (*.txt)|*.txt";
        saveFileDialog1.ShowDialog();
        System.IO.StreamWriter SaveFile = new System.IO.StreamWriter(saveFileDialog1.FileName);
        if (saveFileDialog1.ShowDialog()==DialogResult.Cancel)
        {
            richTextBox1.Text = "CANCEL";
            issaved = false;
        }
        else
        {
            issaved = true;
            SaveFile.WriteLine(richTextBox1.Text);
        }
        SaveFile.Close();
    }

您调用saveFileDialog1.ShowDialog()两次,一次显示它,一次获取结果。你只需要打一次电话。去掉这样一行:saveFileDialog1.ShowDialog();本身,你已经在if条件中这样做了。

编辑:您还需要将所有FileStream操作移动到else块中,以便在删除该行后使其正常工作。这是我编辑过的版本:

    private void SaveAsItem_Click(object sender, EventArgs e)
{
    saveFileDialog1.FileName = "untitled";
    saveFileDialog1.Filter = "Text (*.txt)|*.txt";
    if (saveFileDialog1.ShowDialog()==DialogResult.Cancel)
    {
        richTextBox1.Text = "CANCEL";
        issaved = false;
    }
    else
    {
        System.IO.StreamWriter SaveFile = new System.IO.StreamWriter(saveFileDialog1.FileName);
        issaved = true;
        SaveFile.WriteLine(richTextBox1.Text);
        SaveFile.Close();
    }
}

你也可以完全跳过FileStream,只做一个File.WriteAlltext(saveFileDialog1.FileName, richTextBox1.Text)
