大家好！小弟有个问题，OpenFileDialog这个类我指定了目录但是，程序其他的地方我获取应用程序路径就是这个路径了不知道为什么？

Question

比如我用OpenFileDialog的InitialDirectory指定了路径C:\\ ，但是我其他的窗体使用的是（"文件名"）获取的是应用程序的路径下，但这个文件就直接找我刚才制定的路径下了，这是为什么啊？我试过把InitialDirectory 指定Application.StartupPath但是还是不行，还是原来指定的路径

Answer 1

            OpenFileDialog ofd = new OpenFileDialog();
            ofd.InitialDirectory = Application.StartupPath;
            ofd.RestoreDirectory = true;
            ofd.ShowDialog();

Answer 2

真的没有修改 要不我吧代码给你拿来看看？
private void BtnFileFind_Click(object sender, EventArgs e)
        {
            
                dt.Rows.Clear();
                OpenFileDialog OpenFile = new OpenFileDialog();
                OpenFile.InitialDirectory = @"C:\Program Files\锦研XT-JZ型测水系统校准软件\配置文件";
                OpenFile.Filter = "ini files (*.ini)|*.ini|All files (*.*)|*.*";
                if (OpenFile.ShowDialog() == DialogResult.OK)
                {
                    this.textBox1.Text = OpenFile.FileName;
                    StreamReader stRead = new StreamReader(this.textBox1.Text, System.Text.Encoding.Default);
                    string str = "";
                    int count = 0;
                    try
                    {
                        while (str != null)
                        {
                            str = stRead.ReadLine();
                            if (count > 6 && count < 39)
                            {
                                if (count < 16)
                                {
                                    string[] Tablestr = new string[3];
                                    Tablestr[0] = str.Substring(str.IndexOf("=") + 1, 5);
                                    Tablestr[1] = str.Substring(str.IndexOf(",") + 1, 5);
                                    Tablestr[2] = str.Substring(str.IndexOf(",") + 7, 4);
                                    DataRow newrow = dt.NewRow();
                                    dt.Rows.Add(newrow);
                                    dt.Rows[count - 7][0] = Tablestr[0];
                                    dt.Rows[count - 7][1] = Tablestr[1];
                                    dt.Rows[count - 7][2] = Tablestr[2];
                                }
                                else
                                {

                                    dt.Rows[count - 7][2] = Tablestr[2];
                                }                            }
                            count = count + 1;                        }
                        stRead.Close();
                        this.cbx_OilDischarge.Items.Clear();
                        for (int i = 0; i < dt.Rows.Count; i++)
                        {
                            this.cbx_OilDischarge.Items.Add(dt.Rows[i][0].ToString());
                        }
                        dataGridView1.RowHeadersVisible = false;
                        dataGridView1.DataSource = dt.DefaultView;
                        dataGridView1.ShowCellToolTips = true;
                        dataGridView1.RowHeadersWidthSizeMode = DataGridViewRowHeadersWidthSizeMode.DisableResizing;
                    }
                    catch (Exception)
                    {
                        OpenFile.InitialDirectory = Application.StartupPath;
                        OpenFile.RestoreDirectory = true;
                        stRead.Close();
                        MessageBox.Show("读取配置文件异常!请确认配置文件是否正确", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                    }
                }
                OpenFile.InitialDirectory = Application.StartupPath;
                OpenFile.RestoreDirectory = true;
        }

Answer 3

一楼正解   ofd.RestoreDirectory = true;  //此属性为关闭对话框是否恢复当前设置

Answer 4

你的代码这么给你说吧，你每次执行这个事件肯定都会先打开第一次初始化的目录(@"C:\Program Files\锦研XT-JZ型测水系统校准软件\配置文件";
)因为每次先执行上面的代码.执行顺序和逻辑判断位置的问题，你好好想想

Answer 5

谢谢你 我找到原因了 
OpenFile.RestoreDirectory = true;
这个语句应该放在 if (OpenFile.ShowDialog() == DialogResult.OK) 上面 
也不知道为什么，至于你说的我是在打开按钮里面做的，我关闭这个画面后，打开别的画面就出现这种情况直接找我指定的路径了，没有在关闭前指定恢复吧
