调试后，点新建文本功能，弹跳出提示框，可不管点击确定还是取消，都会跳出保存功能，而我要实现的是只点击确定才跳出保存功能...希望大虾们能帮帮我

你根本没有对这个对话框的值进行判断DialogResult = MessageBox.Show("是否保存？", "信息提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);

            if (richTextBox1.Text != "")
            {
                if (MessageBox.Show("是否保存？", "信息提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Information)  == DialogResult.OK)
                {
                    SaveFileDialog saveFile1 = new SaveFileDialog();
                    saveFile1.InitialDirectory = "C:\\";
                    saveFile1.Filter = "文本文档(*.txt)|*.txt|所有文件(*.*)|*.txt";
                    saveFile1.FilterIndex = 2;
                    saveFile1.RestoreDirectory = true;
                    if (saveFile1.ShowDialog() == DialogResult.OK)
                    {
                        richTextBox1.SaveFile(saveFile1.FileName, RichTextBoxStreamType.PlainText);
                    }
                    else
                    {
                        richTextBox1.Clear();
                    }
                }
            }
            else
                return;

好的...谢谢你，我也是刚学编程的，属于菜虫级别的，多谢前辈指点~~~~

其实我是最近才接触C#的
